摘要: 以血糯(乌黑色,粳稻)和矮秆黄板所(红黑色,籼稻)两个有色稻品种为材料,研究了颖果发育过程中色素沉积以及外界环境因素对色素沉积的影响。除果皮沉积花色素等色素外,有色稻颖果的生长、胚乳发育与常规水稻品种基本相同。花后4~5 d花色素在颖果顶端果皮中开始沉积,接着在颖果两端及背部维管束处的果皮中沉积,然后向整个颖果的果皮扩展,花后10 d整个颖果着色。颖果中花色素主要在花后7~20 d大量积累,花后20 d停止增加。遮光影响颖果着色,且遮光越早颖果着色越差。过高的气温不利于颖果着色,适度的低温能延长颖果的着色时间。

Abstract: The effects of environmental factors on accumulation of anthocyanidin during the development of caryopsis were studied with two colored rice cultivars, Xuenuo(japonica)  and  Aiganhuangbansuo(indica) as materials. The caryopsis growth and endosperm development of colored rice were basically the same as conventional rice, with the exception in its anthocyanidin accumulation in the pericarp. Anthocyanidin first accumulated in the pericarp close to awn(4-5 days after flowering), then to both sides and to dorsal vascular bundle,and last gradually expanded to the whole pericarp at 10 days after flowering. The accumulation of anthocyanidin mainly occurred at  7~20 days after flowering. Shading inhibited the accumulation of anthocyanidin, especially  at early stage.  High temperature went against the accumulation of anthocyanidin and relatively low  temperature  extended   accumulation duration.
