水稻生殖生长阶段不同时期高温热害对产量损失的影响
Effects of High Temperature during Reproductive Growth Phase on Yield of Rice
摘要
Abstract
A pot experiment was conducted in phytotron to simulate the high temperature stress at reproductive growth phase, yield and yield characters were investigated under the high temperature stress with different occurring periods and duration. The results showed, the heading and flowering day was identified as 0 d, high temperature stress has been imposed at the period -9 d、-6 d、-3 d、0 d、3 d、6 d、9 d、12 d across reproductive growth phase and the lasted two duration were 3 days and 5 days, respectively, the sp-kilets setting rate performed same variation tendency between the super hybrid rice variety Y Liangyou 1 and inbred perfect quality rice variety Guiyu 9. The lowest spkilets setting rate appeared at the heading and flowering day, namely 0 d, high temperature damage became more serious as the duration increased. Under the duration 5 days, high temperature stress occurred at the period -3 d re-duced the spkilets setting rate seriously and even more than that of at the heading and flowering day with the duration 3 days. The dif-ferent tolerance to high temperature stress among varieties existed, high temperature tolerance rice varieties should be employed to en-counter the heat damage weather at locality ecological sit where high temperature stress is incident.关键词
