水稻虽是喜温作物,但在开花期遇上高温,便会产生热害,严重影响开花授粉、受精结实。为了寻找耐热性较强的稳产高产良种供生产应用,给筛选耐热性良种提供鉴定指标,我们于1980—1981年在桃源县进行了本试验。 水稻开花期高温对授粉影响的细胞学观察以中稻“盐籼203”和迟熟早稻“
Although rice is a thermophilic crop, it encounters high temperature in the flowering period, which will cause heat damage and seriously affect the flowering and pollination and fertilization. In order to find a stable, high-yielding and heat-tolerant elite for the production and application, and to provide identification index for selecting heat-tolerant elite, we conducted this experiment in Taoyuan County from 1980 to 1981. Cytological observations of the effects of high temperature on pollination during flowering stage in rice “Salt and indica 203” and late mature rice "
