| 摘 要： | 通过对云南省元江县红河流域干热河谷地区相同立地条件下的印度和缅甸两种源多油辣木苗期生长量的连续观测,比较实生苗株高、地径、枝下高、冠幅、开花数和结实量等指标,研究多油辣木苗期生长规律的变化。结果表明,从播种到1年生期间两种源多油辣木的株高、地径、枝下高和开花数在种源间无显著差异,各个时期的生长速率略微不同。两种源多油辣木的冠幅和结实量有较大的差别,印度种源1年生实生苗的冠幅东西向、南北向分别比缅甸种源高12.5%、16.9%,结实量是缅甸种源的5倍,t检验结果显示,两种源多油辣木的冠幅和结实量差异显著(P<0.05)。

| Abstract: | Seedling mass growth from two provenances(India and Myanmar) of Moringa oleifera Lam.under the same site and culturing condition was observated.Seedlings were planted in Yuanjiang county,Yunnan province,which was basically in dry-hot valley of Red River basin.By comparing the plant height,ground diameter,under branch height,crown breadth,the number of flowers and fruit yield,the results showed that:From sowing to annual period,there were no significant differences in plant height,ground diameter,under branch height and flowering numbers between two provenances.For the two provenances,growth rate of each period was slightly different,but between provenances,crown breadth and fruit yield were significantly different.After plantation for a year,for the crown breadth of south to north direction and east to west direction,India provenance produced 12.5% and 16.9% respectively more than Burma provenance.For fruit yield,India provenance produced four times more than Burma provenance.Variance analysis showed that a significant difference(P<0.05) was between the two provenances of crown breadth and fruit yield. |
