摘要
通过在江西山区引种10个不同钙果品系,对其种植后保存率、株高、分枝数和花芽数指标进行调查分析,并采取隶属函数法综合比较了不同钙果品系的生长表现,结果表明:(1)钙果各品系生长表现差异较大,其中保存率较高的是钙果4号和钙果6号,较低的有02-16、钙果3号、S-D和Y08-22;株高钙果4号和03-35最高,最矮的为02-16;分枝数钙果4号、03-35、9号和钙果6号较多,而02-16和Y08-22较少;发芽数较多的有钙果3号、钙果6号、钙果4号和03-35,较少的为钙果5号S-D、9号、02-16等;(2)各生长指标中,变异系数最大的是花芽数,较小的为分枝数和株高,表明分枝数和株高性状在不同钙果品系中表现比较稳定。(3)以株高、分枝数、花芽数和保存率4个指标进行隶属函数值综合比较,可知钙果引种生长表现好的排序依次为钙果4号>03-35>钙果6号>9号>钙果3号>欧李7号>钙果5号>S-D>Y08-22>02-16。
10 different strains of Cerasus humilis were introduced and planting in mountain area of Jiangxi Province, and the survival rate, plant height, branch number and flower bud number index were investigated, besides, the growth performance of different C. humilis were comprehensive evaluated with method of subordinate function values, the results showed that： （1） There are large difference of the growth performance among different strains, C. humilis 4 and C. humilis 4 with higher survival rate while 02-16, C. humilis 3, S-D and Y08-22 with low survival rate, C. humilis 4 and 03-35 with higher plant height while 02-16 with low height, C. humilis 4, 03-35, C. humilis 9, C. humilis 6 with higher branch number while 02-16, Y08-22 with low branch number, C. humilis 3, C. humilis 6, C. humilis 4 and 03-35 with higher flower bud number while C. humilis 5, S-D, C. humilis 9 and 02-16 with low flower bud number. （2） Among the growth index, the largest coefficient of variation was flower bud number and the low coefficient of variation were plant height and branch number, it indicated that the stable performance of plant height and branch number for C. humilis. （3） According to the comprehensive comparison of subordinate function values from four indexes （the survival rate, plant height, branch number and flower bud number）, the order of planting performance form the high to low was： C. humilis 4〉03-35〉C. humilis 6〉C. humilis 9〉C. humilis 3〉C. humilis 7〉C. humilis 5〉S-D〉Y08-22〉02-16.
