不同油橄榄品种扦插育苗效果及容器苗生长特性

Seedling Cultivation by Cutting and Growth Characteristics of Container Seedlings of Olive Cultivars

对Frantoio、Leccino、Pendolino、Maurino、Moraiolo、Coratina和城固32共7个油橄榄品种进行扦插育苗试验,结果表明:不同品种绿枝扦插生根难易程度不一,其中城固32、Frantoio和Pendolino自然生根率分别为82.3%、69.2%和50.8%,为较易生根品种,Leccino、Moraiolo、Maurino和Coratina4个品种的生根率均低于30%,为生根困难品种;油橄榄容器苗普遍具有生长快的特性,两年生容器苗一般都能达到壮苗标准,特别是城固32、Frantoio和Coratina3品种主干生长健壮、新枝抽发有力,具有明显的速生特性;油橄榄容器苗1年中根系有2次生长高峰期,树冠有3次生长高峰期,根冠比随苗龄的增长而逐渐降低。

Experiment was conducted on seedling cultivation by cutting of seven olive cultivars （Olea europaea）. The result showed that it had different rooting capability, among them, Chenggu 32, Frantoio, and Pendolino had rooting rate of 82.3%, 69.2% and 50.8% respectively, whereas Leccino, Moraiolo, Maurino and Coratina had rooting rate below 30%. Container seedlings of tested cultivars had advantage of fast growth and strong in two years, especially Chenggu 32, Frantoio and Coratina with strong stem and new shoot. Olive container seedlings had two root growth peaks and three shoot growth peaks in a year. The root/shoot ratio gradually reduced with seedling age.
