摘要
2005年12月在昆明呈贡七甸进行美国黑樱桃与冬樱花生长量及适应性对比试验,通过4年的观测试验结果表明:美国黑樱桃的平均树高、平均地径和平均冠幅生长量均大于冬樱花,美国黑樱桃和冬樱花的树高生长和冠幅生长差异显著,但地径生长差异较小。冬樱花在2009年3月14日的特大晚霜中所有植株梢头严重受冻,而美国黑樱桃未受冻害,美国黑樱桃的抗霜冻能力显著优于冬樱花。
An experiment of adaptation and growth of Prunus cerasoides and P. serotjna was carried out in Qidian of Chenggong of Kunming City in December 2005. After 4 years＇ observation, it showed that the average tree height, average diameter at base and average canopy increment of P. serotjna were larger than that of P. cerasoides. There was significant variation between both type of trees in height and canopy increment, but not so with diameter at base increment. The trees of P. cerasoides suffered severe freeze injury in ld, March 2009, but that of P. serotjna escaped from it, showing better resistance to coldness.
