On the relationship between the formation of orchid buds and deduction of water

Buds grow from bud primordia, which differentiate into leaf buds and flower buds. Once the bud primordia is differentiated, it is impossible to change it. No matter how you deal with it, you can only make it continue to grow or die. It is impossible to turn flower buds into leaf buds, or vice versa. So how do flower buds form? According to the current research, it is known that the flower bud formation of plants is mainly affected by the ratio of carbon to nitrogen, hormones, accumulated temperature, light length, temperature difference between day and night, high and low temperature and other factors, such as Cymbidium, flower formation factors are mainly diurnal temperature difference, Phalaenopsis is mainly low temperature, rhododendron is mainly accumulated temperature, chrysanthemum is mainly sunshine length, and so on. Of course, any factor of flower formation must be vegetative growth to a certain extent, photosynthate in addition to their own growth, but also have surplus, so as to ensure the smooth completion of reproductive growth. As for the flowering factors of our farmed spring, Hui, Jian and Muran, I personally think: all are affected by the carbon-nitrogen ratio, Jianlan may also be affected by high temperature, why do you say so? Because the flowers of Jian orchid are all in high temperature in summer, and although the flowers of spring and cymbidium are more concentrated, flower buds are found all the year round after domestication, and deducting water into flowers also proves this point. The so-called shade bud Yang flower and aquatic bud xerophytic flower mainly refer to this kind of flower affected by the ratio of carbon to nitrogen. After deducting water, the vegetative growth is inhibited by the lack of water, and the carbohydrate concentration increases and the carbon-nitrogen ratio increases, forcing the bud primordium to differentiate into flower buds. When the light is strong, on the one hand, the production of carbohydrates increases, on the other hand, the water loss is faster, so that the carbon-nitrogen ratio increases and flowers become flowers. As for spraying phosphorus and potassium fertilizer, it is easy to form flowers because phosphorus and potassium fertilizer can promote the formation of carbohydrates and reduce the proportion of nitrogen. Similarly, too much spraying nitrogen fertilizer will increase the proportion of nitrogen but lower the ratio of carbon to nitrogen, thus making the bud primordia differentiate into leaf buds. Long-winded so much, also do not know whether it is clear, improper, please correct, the above content is for reference only.
