政和杏开花物候期观测

The Study Flowering Phenology of Armeniaca zhengheensis

2020年在福建省政和县外屯乡稠岭村,对仅存的6株政和杏野生植株的生长分布情况、生物学特征及开花物候期等进行观测研究。结果表明:政和杏盛花期时间在3月中旬,现存的6棵政和杏始花期存在较大差异,始花期最早的是3月6日,最迟的是3月19日,相差13 d;政和杏开花持续时间14~19 d,盛花持续时间9~15 d,开花持续时间和盛花持续时间,呈现早开花则持续时间长、迟开花则持续时间短的特点。同一植株的东方位、南方位和北方位的枝条开花时间比西方位早1~2 d,同一植株树冠下层花枝开花时间要比上层早2~3 d,观测结果可为政和杏的花期预报、种群繁育提供参考。

The growth distribution,biological characteristics and flowering phonological period of the only remaining 6 wild plants of Armeniaca zhengheensis were observed and studied in ChouLing Village,Waitun Township,Zhenghe County,Fujian Province in 2020.The results showed that the full-bloom stage of Armeniaca zhengheensis was in the middle of March,and there were great difference in the initial flowering period of 6 wild plants of Armeniaca zhengheensis.The earliest flowering time was March 6,the latest was March 19,the difference was 13 days.The flowering duration of Armeniaca zhengheensis was 14~19 days,and the duration time of full-bloom was 9~15 days.The flowering duration and full blooming duration show the characteristics of the time of flowering will lasts longer when Armeniaca zhengheensis early bloom,conversely,the time of flowering lasts shorter when late bloom.The flowering time of the branches in the east,south and north directions of the same Armeniaca zhengheensis plant was 1~2 days earlier than that in the west direction,and the flowering time of the lower flower branches in different canopies of the same Armeniaca zhengheensis was 2~3 days earlier than that in the upper layer.The observation results can provide a reference for the prediction of flowering period and population breeding of Armeniaca zhengheensis.
