14个核桃品种的开花习性及花期物候观察

摘要

The flowering behavior and phenology of 14 walnut varieties grown in Kunming arboretum were observed continuously from 2011 to 2013 .The results showed that the flowering periods of a majority of walnut varieties did not or merely encounter between male flowers and female ones.Accordingly these walnut varieties needed pollinizer. The period of female flowers blooming of Juglans sigilltata cv.‘Dapao’ and ‘Santai’ , which were main cultivated varieties in Yunnan Province, could mostly match the ones of cv.‘Chandler’, ‘Hartley’ and ‘Zijiao 9’.Then these three varieties could be considered as pollination parents of ‘Dapao’ and ‘Santai’.%2011～2013年连续3年在昆明树木园对14个核桃品种进行开花习性和花期物候观察，结果表明，多数核桃品种雌雄花期不相遇或相遇时间较短，需要配置授粉树；云南主栽品种大泡核桃、三台核桃的雌花期与自交9号、强特勒和哈特利的雄花期相遇时间较长，这3个品种可以考虑作为大泡核桃与三台核桃的授粉品种进行配置。
