摘要 对贵州省荔波县野生梅的适应性、果实的理化性质、开花结果习性、物候期等园艺性状进行了研究。结果表明, 荔波野生梅抗旱耐瘠, 适合喀斯特山地发展。在整个野生梅群体内, 果实性状变异较大, 有些单株平均单果重仅104g, 而有些高达28g; 可食部分百分率最低7774% , 最高达8820% 。完全花比例高者达58% ,低者仅98% , 并随年份不同而有差异。以短果枝和针刺状果枝结果为主, 两者占结果枝总数的80% 以上, 并随树龄的增长比例更高, 最高可达99% 。荔波野生梅一般在12 月下旬至1 月上中旬开花, 4 月底至5 月初成熟。 The ecological adaptability,physical chemical characteristics of fruits,habit of flowering and fruiting and phenological phase etc.of wild plum grown in Libo,Guizhou province were observed.The results showed that the wild plum are adaptable to the Carst mountainous area because of its drought and barren resistance.In whole wild plum population,fruit characteristics varied greatly and average fruit weight ranges between 10 4g and 28g,the minimum rate of edible fruit part is 77 74% and the maximum is 88 20%,complete flower rate varies from 58% to 8 8%.Both short and needle like fruit branches are the main fruiting branch which account for 80% of the total,even reaches to 99% for the highest one.The stage of flower is from late December to early January next year and mature from late April to early May.
