一、番茄花芽分化的生理生态 (一)番茄花芽分化的过程番茄苗在真叶展开2～3片到分化8～9片时,生长点就停止叶的继续分化,而分化出花芽(即第一花穗的第一个花)。紧接着在其侧下方分化出第二花,同时,在最终叶和这个花穗之间形成了作为花穗腋芽的新的生长点,进而与第二花的侧下方形成第三花的同时,生长点也生长,分化出叶来。就这样,花逐次地分化,在同一花穗从分化一个花芽到分化下一个花芽,一般约隔2～3天,大约在前一花的萼片形成期就可以看出下一个花的分化。花芽分化约在播种后的25～30天开始,花芽分化节位一般在7～13节叶间,平均第8至第9节。第二花穗的分化是在播种后34～38天,第一花穗分化后9～13天左右。这时在第一花穗已经分化
First, the physiological and ecological differentiation of tomato flower buds (A) tomato flower bud differentiation process Tomato seedlings in true leaves expand 2-3 tablets to differentiate 8 to 9, the growing point to stop the continued differentiation of the leaves, and the differentiation of flower buds (ie the first The first flower of a flower). Followed by differentiation of the second flower from the lower side thereof and at the same time a new growing point is formed between the final leaf and the flower spike as an axillary bud of the flower bud and at the same time a third flower is formed at the side below the second flower, The growth point also grows, differentiating leaves. In this way, the flowers differentiate one after another. From the time a flower bud divides a flower bud to the next flower bud, it usually takes about 2 to 3 days. The differentiation of the next flower can be seen about the sepal formation of the previous flower. Flower bud differentiation about 25-30 days after sowing, flower bud differentiation node is generally 7 to 13 leaves, the average section 8 to 9. Differentiation of the second flower is 34 to 38 days after sowing, the first spike after differentiation about 9 to 13 days. At this moment the first flower spike has differentiated
