Resource Types and Fertility of Pistacia chinensis Bunge in Tang County of Hebei Province
摘要
Abstract
Pistacia chinensis Bunge plays an important role in the aspects of greening,timber, sightseeing,officinal and fuel supply.To know the distribution traits of P .chinensis Bunge in Tang county of Hebei province,explore and make good use of P .chinensis Bunge resource, resources investigation through calls,interview and field survey were done in Tang county between 2012 and 2013,and the fertility and fruit traits among different resources were also studied.The results showed that the exceptional monoecious P .chinensis Bunge trees were found for the first time in Tang county.The distribution of staminate and pistillate inflorescences was highly complex in monoecious P .chinensis Bunge trees.Inflorescences borne on the branches were divided into three categories:staminate and pistillate inflorescences borne on different branches of the same tree,staminate and pistillate inflorescences borne on the same branch, staminate and pistillate flowers borne in the same inflorescence.Four types of inflorescence formation were found:staminate and pistillate flowers formed their own inflorescences,mixed inflorescences,hermaphrodite flower,single-sex flowers and hermaphrodite flower consisted of an inflorescence.Experiments on fertility and fruit traits showed that pollen and ovary from monoecious resource were fertile;male tree as male parent,monoecious trees as female parent got bigger fruit than female tree as female parent.P .chinensis Bunge were monoecious or dioecious, gametophyte of male trees,female trees,the first and the third categories above were fertile. Maybe female parent influenced merits of fruits more largely,there were significant correlation between transverse diameter,longitudinal diameter and per seed weight of a fruit.关键词
