【摘要】 对广东省高州野生稻原生境群体的形态性状进行了详细调查,应用可变类平均法对植株形态性状进行聚类分析.结果表明广东省高州野生稻群体内植株存在丰富的变异,大岭村、福石村、泊水村和朋山村4个野生稻群体之间在表征、种子生产潜力等方面的性状上存在差异,这种差异可能是由于野生稻群落具有不同水分稳定性、水位和干扰强度所造成的.更多还原

【Abstract】 The morphological traits from Gaozhou wild rice populations in Guangdong Province were collected and clustered by using a variable-average method. The results indicated that there were abundant variations of traits in the natural populations, especially significant differences in vegetative organs and seed production potentiality among the populations of Daling village, Fushi village, Boshui village and Pengshan village. These differences may be due to the different water stability, the water line and disturbance strength among the populations.更多还原
