Yellowing (etiolation)

most plants show yellow and other perverted features as they grow in the dark. Plants are unable to synthesize cophylotin in the dark, showing the yellowness of carotenoids, fast-growing between sections, insufficient leaf spread and growth, and underdeveloped roots, tube bundles, and mechanical
tissues
The top of the yellowing seedling embryo shaft of the gemstone plant bends into a hook-shaped shape, the top bud unfolds very slowly, and the sub-leaf does not puff. The yellowing embryo shaft of the cereal plant elongates, and the leaves roll up into a barrel without expanding. In addition, young buds, such as 1000s growing in potato tubers, also appear yellowing when growing in the dark. Yellowing is widespread in bee plants and is not evident in moss plants and naked plants.there is a small colorless mass, the progenitor, in the leaf meat cells of yellowed seedlings. The progena begins to form and accumulate after lighting, and develops into a leafy body for photosynthelial use. Very weak light can eliminate the yellowing phenomenon of seedlings, so that the leaves expand and turn green, return to normal growth. This action occurs through photomines, which is completely different from photogenics through curlytin. The phenomenon of yellowing is an adaptation of plants to the environment. When seeds or other extended organs germinate under the lightless soil layer, the
alsoly
nutrients with limited storage can be used most effectively for the elongation of the embryo shaft or stem, ensuring that the seedlings are unearthed for light. People often use the method of blackout to produce yellow seedlings as food, such as jaundol, garlic yellow and bean sprouts, because cellulose is small and tender and delicious.
