<h1 class="pgc-h-arrow-right" data-track="133" > uses the middle branch cuttings to maintain typical traits</h1>
l, morphology, inclusion composition typical: tea leaves are mostly oval, the middle is wider, corresponding to the plant as a whole, is also the middle is wider, the growth potential is more vigorous. A branch, the largest middle piece, take the middle of the branch cuttings, the highest survival rate, and the new plant grows fast.
The reason for this is the heterogeneity of the branches. It can be seen from experiments that this heterogeneity is manifested in the starch content, the amount of sugar, the ratio of disaccharides to monosaccharides, the types of hormones, and the ratio between each other and affect the hair roots. At various stages of growth and development in new shoots. The leaves of different parts of the same new shoot are the largest in the middle, while the two sides descend according to a certain physiological gradient. Leaf changes are not only manifested in morphological size, but also in growth period length and inclusion changes.
2. The central branches can increase production, which lies in the strong function of physiological and biochemical aspects:
(1) The photosynthesis of the middle branches of the tea plant is the strongest: according to Huang Jingchun in Zhaoqing, Guangdong Province, the photosynthetic intensity of leaves in different parts of Yunda was measured. Although the light intensity received by the middle leaf is not as good as that of the upper leaf, the photosynthesis is higher than that of the upper and lower leaves. This is due to the fact that tea plants grow under forest shading conditions during phylogeny, forming habits with strong use and absorption of diffuse light. From a genetic point of view, due to the heterogeneity of the branches affecting the differences in leaves, this difference is related to the activity of genes. Gene activity not only varies with cell type, but also the same cell type at different stages of development.
(2) The middle layer of the leaf is a mature leaf, which is the best in terms of leaf area and leaf dry weight; the internal anatomy and the ratio of chlorophyll A and B are superior to the upper layer. Therefore, the viability of the central leaves is high.
(3) The photosynthesis of a branch relative to the whole is also the most central leaf of the branch. The actual and net photosynthetic rates of the branches are the strongest in the upper middle and middle parts, further indicating that the internal physiological functions are similar not only in appearance to the middle of the plant.
(4) The middle buds of the tea plant are dense. The leaf area is the largest, the physiological activity is vigorous, the closer to the center of the tea tent, the number of leaves is large, the yield is high, and the growth potential is strong. In general, the production of the center increases by 20-50% compared with the surrounding area, and the root rate of cuttings is also higher than that of the edges.

<h1 class="pgc-h-arrow-right" data-track="131" > the genetic potential of asexual offspring at different sites of plants</h1>
According to the biological holographic law, if asexual reproduction is carried out from a certain point, then the resulting asexual individual has a strong genetic potential for the specific trait of this point. As far as a branch and the whole tea tree are concerned, the new plants that take the lower branches and cut the roots and the upper branches reproduce are easy to flower, which is caused by the heterogeneity of the branches. It manifests itself in:
1. Heterogeneity of branches from anatomical structure:
(1) The base number of the leaf original decreases with the increase of the branch part. The degree of differentiation of young leaves also tends to weaken as the branch area increases.
(2) Differences in the tissue structure of the cross-sectional surface of the stem: the thickness of the stem in the transverse section, the thickness of the cortex, the thickness of the phloem and the original formation layer, and the thickness of the primary xylem all show a trend of gradual reduction from the low branch to the primary branch. The thicker the original formation layer, the stronger its meristem capacity, the faster the phloem and xylem, and the higher the efficiency of material transportation. The amount and state of the cytoplasm content can also reflect the strength of cell metabolism, and the nucleoplasm content of low-ended cells is large and clear, indicating that its metabolism is vigorous.
(3) Difference in the number of flowers: Huang Yihuan observed that the number of flowers on different new shoots of tea plants varies greatly, and there are almost no flowers on the new shoots of 20 and 50cm, but with the increase of the branches, the number of flowers also increases. In summary, the lower the part of the tea plant, the stem tissue appears as a typical "juvenile type", and as the part increases, the cells gradually age.
2. Causes of branch heterogeneity:
(1) Holographic embryos are specialized embryos on an organism that are at a certain stage towards new ontology, and are units of biological structure, such as leaves and branches, and take cells as the least developed holographic embryos. At the beginning of the development timeline, and the whole itself is the most developed holographic embryo, the development degree of other holographic embryos is located between the starting point of the development timeline and the development stage of the individual as a whole, and its development is stopped at a certain stage, simply growing or specializing. This is why the branches appear heterogeneous.
Genetics believes that the individual development age is different, so the differentiation of cells is different, it is related to the activity and regulation of genes in the cell, in a certain stage of development some genes are in a state of not being inhibited and transcribed, the formation of mR-NA may also be some of the translation of a large number, and some of them are less translated or temporarily not translated, which can make the original same cells gradually tend to be different, so that their physiological activities, metabolism have changed.
(2) Heterogeneity of branches due to different stagnation points of holographic embryo development, that is, stages. This makes the central branch typical. When the branches are in the cuttings, due to the different lag points of each part, the adjustment ability of the growing plants is different, and the time of the flowers of the roots and newly grown plants is different. During ontology, the ability to adjust weakens with development, and during phylogenetic development, the ability of holographic embryo fragments to adjust new intact holographic embryos and develop into new plants weakens with evolution. If cuttings propagate with branches with typical traits according to these laws, then these cells with staged qualitative changes pass on the qualitative changes to the daughter cells. The nascent organization also has certain stage characteristics. Make cuttings typical and prevent premature aging that enters the reproductive stage prematurely. Then the use of directional cultivation and selection methods, to maintain favorable traits, through generation by generation selection, consolidation, strengthening will make the traits more suitable for people's needs. This is also the reason why some plants are particularly typical in asexual reproduction. It has some significance for the purification of clones in the future.

<h1 class="pgc-h-arrow-right" data-track="129" > the holographic relationship between the root system and the aboveground part</h1>
As mentioned earlier, rhizomes and leaves have a holographic relationship with each other, the leaf veins are the planarization of branches, and the roots correspond to each other one by one. Generally, the tree-type main pole is upright and tall, and its main root is also deep and the root system is more vertical; while the shrub-type variety has a more extensive tree posture, its root distribution is also wider, and the main root is shallower. Throughout the growth cycle of the tea plant, the seedlings are mainly straight roots, and the main roots are obvious. At this time, the branching form of the tea tree is basically uniaxial branching; after that, the root width continues to expand, and the tree width also increases. The two are closely related. In production practice, the fertilization of single-bush tea trees is often based on the outer edge of the branches to dig a trench to fertilize, in order to facilitate the absorption of roots to absorb nutrients.
In order to limit the height of the tea plant, in addition to pruning, its main root is often broken to reduce the height. From the holographic law point of view, the taproot is shortened, and the growth of the main rod is correspondingly weakened. After several years of colonization, the branches are aging due to picking, and their main roots are broken by the method of deep ploughing, so that the weight of the fine roots (dry matter) and the weight of the lignified roots are improved, and the fertility of the upper part of the ground is exuberant, a large number of new shoots germinate, and the dry matter is increased accordingly, and high yield is achieved.

<h1 class="pgc-h-arrow-right" data-track="92" > use tea cell culture to produce secondary metabolites</h1>
Tissue culture using plant cells. To cultivate a large number of secondary metabolites. It is an integral part of bioengineering technology, and is currently mainly used for the production of drugs, pigments and aromatic raw materials. It is developing into an emerging scientific research industry system.
The content of tea polyphenol compounds is as high as 15%-35% of the dry weight of fresh leaves, which is the main substance constituting the style and quality of tea, and also has important application value in medicine and health care, food industry and so on. However, most of them are directly extracted from tea leaves, so the price is very high. At present, China, Japan, the United States, South Korea, Singapore and other countries are stepping up research.
Tea leaf cell is a holographic embryo, and is a holographic embryo with the lowest developmental stage, which not only has the totipotency of cell development into a plant, but also has the biochemical pathway of the overall synthesis of secondary metabolic chemical components of tea plants. Under certain culture conditions, it can be carried out along the biosynthetic and metabolic pathways. According to Wang Li et al., the culture cells of tea plants can maintain the ability to synthesize phenolic compounds, but most of them are simple catechins, and very few ester catechins are synthesized, which is similar to the initial metabolic pathway of catechin gallates in the new shoots of tea trees in which polyphenols in young leaves are formed under esterification. However, free gallic acid banks may be a major factor limiting the formation of complex catechins in cultured cells.
In order for the bioabolic pathway of tea polyphenols to proceed smoothly under in vitro conditions, it is necessary to pay attention to the required external conditions, such as light, nitrogen levels, hormone concentrations, types and ratios between each other. This allows the metabolic pathway to proceed in the direction required by humans under specific environmental conditions.

<h1 class="pgc-h-arrow-right" data-track="146" > directly multiply organs using holographic muscles</h1>
A plant is not all it needs, but some of its organs. If the tree needs its fruit, the tea tree needs its buds and leaves to produce tea. The current tissue culture is to use the totipotency of the cell to obtain the entire plant and reuse its organs, resulting in waste. According to holographic theory, an organ is a holographic embryo, a specialized embryo with a certain stage of development, which can be directly obtained under specific conditions through the development and specialization of cells. It has been reported that the United States has been able to use the cells of cotton leaves, stems, and roots and fruits to first form a nodular guaiac group in semi-solid medium, and then put it into a solid suspension incubator, and the cells grow to form cotton fibers. without forming other parts of the cotton. This cotton fiber can be directly used to make gauze and bandages for use in the infirmary.
From this point of view, the conditions for direct reproduction of organs are: conditions that promote the development of cells to new ontology; trophic and hormonal conditions that holographic embryos specialize to a certain organ. It may be more direct and faster to grow this organ directly from cells from holographic embryo-organs that have been specialized. Therefore, the use of tea leaf leaf cells (or other somatic cells) to directly reproduce leaves, the utilized part of humans, is entirely possible and far-reaching.
