杂交水(禾刀)增产明显,可是目前制种与繁殖产量仍然不高,其原因虽多,但花期不迂是主要的。在予测花期的摸索中,我们发现“重生叶”的出现与幼穗分化发育的时间有密切的关系。什么是“重生时”?水(禾刀)在生长发育过程中,叶片一般是互生的,可是在从营养生长转入生殖生长时期,则出现一些植株,其叶片着生在茎的一边,表现为重生,我们称之为“重生叶”。
Hybridization (Wo knife) yield significantly, but the current production and breeding yield is still not high, although its many reasons, but the flowering is not important. In exploring the flowering period, we found that the emergence of “rebirth” is closely related to the development of young spike differentiation. What is “rebirth time”? Water (Wo knife) in the process of growth and development, the leaves are generally alternate, but in the period from vegetative growth to reproductive growth, there are some plants, the leaves were born in the side of the stem, the performance For rebirth, we call it a “rebirth.”
