| 摘 要： | 观察了10个黄麻圆果种(Corchorus capsularis)和4个黄麻长果种(C.olitorus)选系材料在不同光周期处理下的开花习性.方差分析表明各材料对光周期的反应存在显著差异,在12.5小时光周期下,圆果种材料UO/MC8122和长果种材料IJO/X/087的开花天数明显较长,而且在12.5小时、13.0小时和13.5小时三种光周期处理下的变幅较小.这一结果表明,IJO/MC8122和IJO/X/087可作亲本材料用于黄麻品种改良以选育对日长广适应的新品种.

| Abstract: | Ten selected accessions of white jute ( Corchorus capsularis )and four selected accessions of tossa jute ( C.olitorius ) were grown in pot culture for observing their flowering behavior under different treatments of photoperiods. The variance analysis showed that the response of accessions to photoperiod was significantly different. Days to flower of white jute accession IJO/MC-8122 and tossa jute accession IJO/X/087 were obviously longer under 12.5 hrs photoperiod and showed narrower fluctuation among the three photoperiodic treatments of 12.5 hrs, 13.0 hrs and 13.5 hrs. The results obtained suggested that accessions IJO/MC-8122 and IJO/X/087 can be utilized as donors in varietal improvement program for developing wide adaptable varieties to day length. |
