把花药培养作为育种手段,我国首先在烟草、水稻、小麦方面应用,并育成了新品种,目前仍处于世界领先地位。近年来,为了提高花粉植株的诱导频率,许多科学工作者,在雄核发育的途径、外源、激素、变温处理等方面进行了研究,并取得了一定的进展。为了探索目前小麦花粉植株诱导频率低的原因,我们在培养条件的温度因素对小麦雄核初始发育的影响方面进行了研究,为进一步提高诱导频率提供依据。 Anther culture as a means of breeding, China’s first tobacco, rice, wheat applications, and bred new varieties, is still in the world’s leading position. In recent years, in order to improve the induction frequency of pollen plants, many scientists have made some research in the ways of the male nucleus development, exogenous, hormones and temperature-changing treatment, and have made some progress. In order to explore the reason of the low induction frequency of wheat pollen plants, we studied the influence of temperature factors on the initial development of wheat nuclei, and provided the basis for further improving the induction frequency.
