The results showed that: high night temperature can accelerate leaf appearance of early-season rice seedlings obviously,and improve the quality of seedlings significantly,accelerate tillering and enhance the effective panicles.

与夜间常温对照相比,夜间高温处理明显加快早稻的秧苗出叶速率,显著提高秧苗素质;有利于分蘖的发生和生长,提高有效穗数。

The results showed that there was not a significant difference between early maturing hybrids and late maturing ones in leafing rate,young panicle differentiation duration(from young panicle initiation to heading) and young panicle differentiating rate,and grain filling duration(from head.

结果表明:早熟组与迟熟组在抽穗灌浆历期、幼穗分化历期及速率、相对出叶速率方面差异不显著,其全生育期的显著差异主要是营养生长期长短不同造成的;早熟组因为幼穗分化起始时间早、营养生长期短而表现早熟;早熟组的有效穗、每穗总粒数、每穗实粒数、结实率与迟熟组无显著差异,但经济产量与单株生物产量均极显著低于迟熟组,其主要原因分别是千粒重较低和植株较矮。

Quantitative trait loci (QTLs) affecting total leaf number of the main stem, leafing rate at two different growth stages, heading date, and plant height in a recombinant inbred lines (RIL)population from the cross Lemont (japonica)×Teqing (indica) were investigated using a complete RFLP map with 182 marker loci.

用一张具有 182个 RFL P标记的分子连锁图谱和一套重组自交系 ( RIL)群体 ,对水稻植株主茎总叶片数、叶片生长速率、抽穗期和株高等数量性状进行 QTL区间作图研究 ,定位了影响水稻出叶速率的 8个 QTL ,主茎总叶片数的 2个QTL、抽穗期的 3个 QTL和株高的 4个 QTL。

Leaf phenology has long been thought to evolve to maximize plant carbon gains, and it reflects plant life history strategies for exploiting resources.

3)相关分析和回归分析都表明,叶寿命与出叶时间和落叶时间显著关联,但早出叶对叶寿命的延长可能更为重要,因为早出叶相对于晚落叶在物种资源利用上比较具有优势。

The leafing rate of fourteen cultivars were estimated based on the interval sowing experiments and the rapid leafing genotype at the vegetative growth stage in an indica cultivar Yanhui 559 was discovered.

通过对14个水稻品种分期播种试验,发现在籼稻品种盐恢559中存在一种营养生长期快速出叶基因型。
