引言柑桔种子具有多胚的特性,因其有性胚在种子发育过程中多数败育,播种所得植株大多数由无性胚发育而成,能保持母本植株的特性,所以,大面积发展柑桔可以进行实生播种而保存品种固有特性,这也是栽培柑桔与一般果树的特异之处。生产上的需要,促使人们对柑桔种子质量的重视,开展有关柑桔种子生活力的保持与测定等一系列种子生理的研究。 Introduction Citrus seeds have the characteristics of multiple embryos. Because most of their sexual embryos are aborted in the process of seed development, most of the plants obtained from sowing are developed from vegetative embryos, which can maintain the characteristics of female plants. Therefore, Oranges can be sown to preserve the inherent characteristics of varieties, which is also the cultivation of oranges and the general fruit of the peculiarities. Production needs, prompting people’s attention on the quality of citrus seeds, to carry out the maintenance and determination of citrus seed vigor and a series of researches on seed physiology.
