| 摘 要： | 冬季干旱的果园,幼年桃树早修剪能提高花芽越冬力(即减轻冻花芽)早剪比晚剪提高了冬季和早春花芽中17种氨基酸总量、与早剪提高了花芽越冬力一致。17种氨基酸中有14种其含量变化趋势与总量相同,另外3种其含量变化趋势与总量则不同、早剪对其影响无规律性表现。

| Abstract: | This study goes on in the winter 1982//83 and 1983//84.It was observed that overwinfering of the flower buds,and was analysed that 17 amino a- cids content in the flower buds,xylem and phloem of annual branch in the different period during winter. Early pruning(in 11 mon)on the young peach trees can be lighten inju- ry of flnwlr buds in the spring,and increased total amino acid content be- fore sprouting during spring,this is identical with early pruning enhance the overwintering ability and else is one of ... |
