the tolerance to heat induced spikelet sterility of rice cultivars is closely related to the length of dehiscence at the basal part of thecae. In general, the longer the basal dehiscence, the larger the number of pollen grains on the stigma; this reduces the risk of floret sterility. The length of basal dehiscence, therefore, is the key trait for stable pollination under heat conditions. 如上,關(guān)于水稻高溫?zé)岷χ聻?zāi)機理的描述,本人農(nóng)學(xué)基礎(chǔ)薄弱,求準確解讀,謝謝! |

| 耐熱誘導(dǎo)的水稻品種小穗不育與孢子膜基底部位開裂長度密切相關(guān)。通常,基底部位開裂越長,柱頭上的花粉數(shù)量越大,這就降低了小花不育的風(fēng)險。因此,基底部位的開裂長度是高溫條件下穩(wěn)定授粉的關(guān)鍵特征。 |
