Characteristics of floral dynamic and breeding system of Lycium ruthenicum
摘要
Abstract
Field investigation was performed on the floral syndrome ,pollination characteristics and breeding system of L ycium ruthenicum by continuous observations and analyzing data of out‐crossing index ,pollen‐ovule ratio ,fruit‐set ratio and seed‐set ratio .The results were as follows :under natural conditions ,the flowering stage of populations was about 120 days from May to September ,the life span of a single flower was about 2 - 3 days .The results showed that pollen viability of L .ruthenicum was more than 93 .2% during the period after flowering .Pollen viability decreased 2 .97% after the 15th day ,stigma receptivity was in the strongest condition on the first and second day after bloom ‐ing ,and then decreased after the third day .It showed that the breeding system was out‐crossing ,part self‐compatibili‐ty ,when comparing the results of pollination experiments with the results of out‐crossing index and pollen‐ovule rati‐o .Hand pollinations improved reproductive success ,suggesting that sexual reproduction may be influenced by pollen limitation and less pollinators in nature .关键词
