What is the main structure of Zanthoxylum bungeanum flower?
Pepper flowers are small, white or green-white, and the flower structure can be divided into calyx, corolla, stamen, pistil and other parts. After 4 ~ 5 days of flowering, it gradually falls off with the growth of ovary. Stamens are composed of five. Anthers around the pistil, flush with or slightly higher than the stigma of the pistil, are called normal flowers or long-column flowers. Pepper flowers open downwards, the anthers crack when they are mature, and the pollen is scattered and falls on the stigma close to each other for pollination.
After flowering, fruit can only be produced through two physiological processes: pollination and fertilization. There is a lot of pollen in the anther of stamens, which will be scattered from the anther when the flowers mature.
Root characteristics of pepper
The root system of pepper is not as developed as tomato and eggplant. The taproot elongates downward, and the lateral root branches around to form the root system. The main function of roots is to absorb, store and transport water and nutrients in the soil for the growth and development of pepper. In addition, it also plays the role of fixing plants and supporting main stems to prevent lodging.
The main root of pepper is thick on the top and thin on the bottom. In loose soil, it can generally enter the soil layer 40 ~ 50 cm. The growth of transplanted pepper is inhibited because the main root is cut off, and the depth is generally 25 ~ 30 cm. With the growth of taproots, lateral roots are constantly produced. The lateral roots are the most in the depth of 5 ~ 20 cm underground, generally about 30 ~ 40 cm long, and small branches are regenerated on the lateral roots to form root systems.
