植物无融合生殖鉴定方法的研究进展

由于利用无融合生殖途径可以固定杂种优势，从而改良现有植物的育种策略，因此对无融合生殖的研究已成为生物学科的新生长点，为了利用植物的无融合生殖，首先必须建立，发展和完善一套简单，准确的鉴定体系，目前有关植物无融合生殖的鉴定的方法，主要可以分为5大类型：（1）形态学观察法；（2）显微观察法；（3）生化鉴定法；（4）分子生物学的方法；（5）其它方法，主要对以上5类方法的各各鉴定方法进行了介绍，对几种已被证实有效方法的优缺点进行了比较，并就今后的改进方向进行了探讨。

The methods for identification of apomixis in plant

Apomixis is a mode of reproduction (asexual propagation through seeds) that exists in many plants from different botanical families.By producing crops that produce asexually through seeds,we can greatly hasten the development of new higher yielding hybrid varieties,therefore,apomixis attracts considerable theoretical interest.Breeding and manipulating apomictic species will require reliable and efficient procedures to screen for mode of reproduction.This paper presented five screening procedures for apomixis,i.e.morphological methods,cytological sectioning methods,biochemistry approaches,molecular approaches and other methods.The relative advantages or disadvantages of the screening procedures presented here are discussed.
