摘要
采用来自53—24°N野生大豆(Glycine soja)26份为材料,在8—18小时八种光照条件下研究并提出了来自各纬度材料在控光条件下的开花临界光周期(CFCP)。分析代表性纬度野生大豆在当地自然条件下的光周期变化动态与开花的关系,提出了自然条件下的开花临界光周期(NFCP)。CFCP与NFCP数值近似。50°N材料为16—16.5小时;45°N材料为15—15.5小时;40°N材料为14.5小时左右;35°N材料为14.0小时左右;30°N材料为13.5小时左右;25°N材料为13小时左右;还提出了控光开花临界光周期与结荚期、成熟期、营养器官、结实器官生长之间的密度关系。讨论了确定开花临界光周期的方法和意义。
The flowering coritical photoperiod (FCP) of wild soybean (G·soja) from various latitudes under photo -controlled conditions (8, 13, 13.5, 14,14. 5, 15, 16.5, 18hr./day) were analysed. The FCP consisted of CFCP (FCP under controlled conditions), NFCP (FCP under natural conditions). Synthesizing the data of CFCP and NFCP, it was summerized that the FCP of accessions from different latitudes were approximately as follows: 50°N: 16-16. 5hr. ,45° N:15-15.5hr. , 40°N:about 14.5hr. , 35°N:about 14hr. , 30°N:about 13. 5hr. , and 25°N: about 13hr. CFCP not only restricted flowering but restricted the days from flowering to podding, the days from flowering to maturity and the vegetative and reproductive growth also. The method of FCP determination of soybean was discussed.
