日本垂枝樱花在武汉的生物学性状观测

Observation of Biological Characteristics of Drooping Branch Cherries Introduced from Japan in Wuhan City

摘要:

摘要：本文观测了从日本引进的5个垂枝樱花品种在武汉2014年和2015年两年间的部分生物学性状变化，包括对成活率、成枝力、生长势、落叶期、叶芽萌动期、展叶期、抽梢期、花芽萌动期、初花期、盛花期和落花期等指标的观测结果。研究表明：重瓣品种‘八重红枝垂’成活率最高，‘枝垂樱’和‘红枝垂’两个单瓣品种花期较早，‘枝垂樱’与‘菊枝垂’一起搭配应用于园林工程，可使垂枝樱花的赏花期持续达40多天。

Abstract:We observed the growth characteristics of five varieties of drooping branch cherries in Wuhan during 2014 and 2015, which were introduced from Japan, including survival rate, branching ability, growth potential, defoliation period, leaf bud germination period, leaf expansion period, shooting period, slightly drawn flower bud sprout period, early flowering period, flowering period and flower fallen stage. The results showed that the survival rate of  Prunus pendula ‘Pleno rosea’ was the highest, and Prunus pendula‘Pendula’ and Prunus pendula‘Rosea’were two earlier floweringvarieties with single petal,and the collocation application of  Prunus pendula ‘Pendula’ and Prunus jamasakura ‘Plena pendula’ in landscape engineering, the flower period of Chui branch Sakuracould last for more than 40 days.
