摘要

将稻穗置不同种类、浓度的酸溶液中浸泡后,观察其对颖花开花及颖花活性的影响,发现0.5%-10%的甲酸、乙酸和丙酸均能显著地诱导水稻开颖。当甲酸浓度在0.5%-1.5%、乙酸和丙酸浓度在0.5%-2%的范围内对颖花无不良影响。硝酸、盐酸和硫酸等在一定的浓度下能诱导开颖,但同时又对颖花产生伤害。

Abstract

The effects of immersing rice panicles in various concentrations of several acids on the glume opening and vitality of pollens were observed. We found that glume opening could be promoted by formic acid, acetic acid and propanoic acid between 0.5%-8% concentration. Formic acid (0.5%-1.5%) acetic acid (0.5%-2%) and propanoic acid (0.5%-2%) had no bad effect on glumes. Though hydrochoric acid, nitric acid and sulphuric acid could also promote glume opening at certain concentration, their acidity were so strong that the glumes were damaged seriously and the pollens would lose vitality.
