马尾松插穗生根能力的家系变异与选择效应
Variation among families on rooting ability of masson pine cuttings and selection effects
摘要
Abstract
Semi-lignified cuttings collected from cutting orchard of masson pine ( Pinus massonian Lamb. ) , which established by la(19 families) , 3a(18 families) seedlings as the ortet, were used for cutting test at intelligent greenhouse. Rooting rate, number of roots per cutting, the longest root length, average root length as weii as height of la steckiings were studied at the level of family. The results showed that;there were significant differences between each rooting property and all properties under strong genetic control. Rooting effect index was a preferable factor for rooting ability evaluation. Through the result of correlation analysis of different rooting indicators, however, rooting rate maybe more practicable and reasonable. On the base of family selection, cutting orchard establishment can obviously enhance the ability of cutting propagation. Choose the superior families with high rooting rates for cutting orchard establishment is the effective way of cutting propagation of masson pine.关键词
