Abstract

The invention discloses a compound for promoting blooming of male and female parent glumous flowers of hybrid rice, which is prepared from jasmones and analogues thereof, 1, 2-propylene glycol and triton X-100 according to a certain proportion. 1, 2-propylene glycol and triton X-100 are added, so that the induction effect of the jasmones and analogues thereof on the expression of osmoregulation substance accumulation related genes, the expression of moisture transport related genes and the expression of cell expansion related genes in the slurry tablet can be enhanced; further, by promoting accumulation and permeation of regulating substances in the pulp and promoting water absorption and swelling of the pulp, early and concentrated blooming of male and female parent spikelet of hybrid rice is promoted, and the promoting effect of jasmones and analogues thereof on blooming of rice spikelet is remarkably enhanced. Even if the dosage of jasmones and analogues thereof is low, the compounded agent can still promote the hybrid rice male and female parent spikelet to bloom in advance and in a concentrated manner by reasonably applying the compounded agent, so that the hybrid rice male and female parent outcrossing maturing rate is increased by solving the problem that the hybrid rice male and female parent spikelet does not meet with each other when the hybrid rice male and female parent spikelet is bloomed.

Description

Technical field [0001] The present invention belongs to the field of plant growth regulator technology, specifically relates to a compound agent that promotes the opening of hybrid rice parents ben ying flower, suitable for solving the problem of hybrid rice parents this flower. Background [0002] Hybrid rice has the advantages of high yield and strong resistance, and the promotion and planting of hybrid rice has made outstanding contributions to solving China's grain problems. However, in the process of hybrid rice propagation, it is often encountered that the parents do not encounter problems when they are flowers. Flowering does not meet mainly refers to the cross-breeding rice within 1d of the parents of the peak of flowering do not meet, that is, the parents of the peak of flowering are misplaced. The absence of flowering is one of the main limiting factors for increasing the yield of hybrid rice breeding. The lack of flowering results in low yield and low efficiency of hyb...
