北京东灵山地区等齿委陵菜(Potentilla simulatrix)的传粉生物学
《北京师范大学学报(自然科学版)》2009年第2期183-187,共5页张玉芬 鲍蕾 
国家自然科学基金重点资助项目(30430160)
对北京东灵山地区克隆植物等齿委陵菜(Potentilla simulatrix)自然种群的开花行为观察发现:等齿委陵菜种群花期较长(约3个月),但单花花期较短(1~2d),每个基株的花期平均(14.6±0.7091)d(n=15),同一基株内不同花的花期完全...

Variation in Floral Sex Allocation and Reproductive Success in Sequentially Flowering Inflorescence of Corydalis remota var. lineariloba(Fumariaceae)被引量:6
《Journal of Integrative Plant Biology》2009年第3期299-307,共9页Yan-Fei Zeng Wei-Ning Bai Yu Zhou Da-Yong Zhang 
Supported by the National Natural Science Foundation of China (30430160).
In hermaphroditic plants, female reproductive success often varies among different positions within an inflorescence. However, few studies have evaluated the relative importance of underlying causes such as pollen lim...

Increased Maleness at Flowering Stage and Femaleness at Fruiting Stage with Size in an Andromonoecious Perennial, Veratrum nigrum被引量:6
《Journal of Integrative Plant Biology》2008年第8期1024-1030,共7页Wan-Jin Liao Da-Yong Zhang

虫媒传粉植物与其传粉者之间的相互作用被认为是被子植物花多样性的一个重要选择压力。这种相互作用体现在植物对传粉者的吸引以及传粉者行为对花粉的转运两个方面。本项研究通过去除不同的花部器官研究了草乌(Aconitum kusnezoffii)对...

Pollen and Resource Limitation in Veratrum nigrum L. (Liliaceae), an Andromonoecious Herb被引量:5
《Journal of Integrative Plant Biology》2006年第12期1401-1408,共8页Wan-Jin Liao Qing-Fa Song Da-Yong Zhang 
Supported by the Natfonal Natural Science Foundation of China (30125008 and 30430160).We thank Tian-Xiang Wang (Beijing Normal University, China) for field assistance and Quan-Guo Zhang (Beijing Normal University, China) for comments on the manuscript.
Pollen limitation and resource limitation were invoked to account for the pattern that flowering plants produce more flowers and ovules than fruits and seeds. This study aimed to determine their relative importance in...
