极低、高范围内的温度影响小穗生成、熟和最终籽粒产量。

Temperature within extremely low and high levels, affected spikelet formation, ripening, and final grain yield.

结果表明，我国多数杂交水稻的直链淀粉含量较高，胶稠度硬，糊化温度和籽粒伸长率中等；

The results indicated that most of the Indica hybrids had high amylose content (AC), hard gel consistency (GC), intermediate gelatinization temperature (GT), and medium grain elongation (GE);

籽粒灌浆速度主要受温度调控，但前提条件是需有充足的光照。

The study also suggested that the grain-filling rate of rice was mainly adapted by temperature under the condition of enough light.
