库尔勒香梨3种枝型开花动态研究
Study on Flowering Dynamics of Three Clades in Korla Fragrant Pears
摘要
Abstract
Korla fragrant pear is a unique pear cultivar native to Xinjiang,and its flowering dynamics and responses to temperature and humidity changes are crucial for ensuring effective pollination.This study aimed to investigate the flowering dynamics at the tip,middle,and basal parts of branches,as well as the correlations between temperature,humidity,and branch flowering behavior,to provide theoretical and data support for improving pollination efficiency during the flowering period.The flowering dynamics of three clades,i.e.long,medium-long,and short,were observed,and the number of open flowers was recorded.The flowering status of different parts of the inflorescence and branches(base,middle,and tip)was analyzed,together with the correlations between flowering and environmental factors.Results showed that long branches had higher numbers of open flowers per branch and per inflorescence compared with medium-long and short branches.From April 6 to 12,the number of open flowers increased significantly in all 3 types,with over 95%of flowers in full bloom,marking the peak flowering period.At this stage,flowering dynamics showed a highly significant correlation with temperature(correlation coefficient>0.85)and a moderate correlation with humidity(correlation coefficient≈0.50).Therefore,monitoring temperature changes during this critical flowering period is of great theoretical importance for improving pollination efficiency and yield in Korla fragrant pear.关键词
