油橄榄雄花分化比例与花序轴、叶片内源激素含量及产量的关系
Relationship between male flower differentiation ratio and inflorescence axis, endogenous hormone content and yield of Olea europaea
摘要
Abstract
In the area of Bailongjiang Valley in southern Gansu, 10 year old olive variety 'Laixing', 'Fu'ao', 'Ezhi 8' and'Chenggu 32' were taken as test materials. In flowering period(May),flower bud leaves,leaf bud and inflorescence axis were col-lected,respectively. High performance liquid chromatography (HPLC) was used to determine GA3, ZR, ABA and IAA. The per-centage of male flower differentiation and the yield per plant were collected during the flowering season. Among the 4 varieties,'Ezhi 8' and 'Chenggu 32' showed a typical male complete monoecious phenomenon. 'Laixing' and 'Fu'ao' have little or no differentiation of male flowers. The proportion of male flowers for 2 years was:'Chenggu 32'(37.5%±18.91%,31.74%±13.24%),'Ezhi 8' (18.73%±8.74%,21.31%±6.66%),'Laixing'and 'Fu'ao' no male flower differentiation. The content of endogenous hormones in flowering period showed that except for GA3,the contents of other 3 kinds of hormones in inflorescence axes were higher than those in leaves. A certain proportion of male flowers on the inflorescence axis 'Ezhi 8'and'Chenggu 32'showed higher levels of IAA and ZR in 3 sampling sites,and lower ABA levels.The high ZR/IAA and ZR/ABA values in the inflorescence axis promoted male flower differentiation. The yield test showed that the'Chenggu 32' and'Ezhi 8' which had the phenomenon of male complete plant were more stable.关键词
