Effect of water extracts of larch on growth of Manchurian walnut seedlings

研究被进行从象根那样的不同部分检测水摘录的效果，吠叫，分叉并且长叶，在二树种之间的成年落叶松， Larix gmelini，核桃树长果核桃树的生长上的树， Juglans mandshurica，幼苗和他感酌。四集中(100g · k g^(-1), 50 g · k g^(-1), 25 g · k g^(-1) 和 12.5 g · k g^(-1)) 为每种摘录作好准备。结果证明有低、中等的集中的水摘录加速了领子直径的生长并且增加了生物资源和核桃幼苗的根 / 射击比率。水从树枝提取并且与低、中等的集中吠叫加速了幼苗的高度生长，当那些稍微从叶子和根减少了时幼苗的高度生长。水的申请落叶松提取的事实可能改进了核桃树长果核桃树属性的生长到在二树种之间的他感酌。

A study was conducted to detect the effect of water extracts from different parts such as root, bark, branch and leaf, of adult larch, Larix gmelini, trees on growth of Manchurian walnut, Juglans mandshudca, seedlings and the allelopathy between the two tree species. Four concentrations （100 g. kg i, 50 g. kg^-1, 25 g. kg^-1 and 12.5 g. kg^-1） were prepared for each kind of extracts. Result showed that the water extracts with low and moderate concentrations accelerated the growth of collar diameter and increased biomass and root/shoot ratio of walnut seedlings. The water extracts from branches and barks with low and moderate concentrations accelerated the height growth of the seedlings, while those from leaves and roots slightly decreased the height growth of seedlings. The fact that application of water extracts of larch improved the growth of Manchurian walnut attributes possibly to the allelopathy between the two tree species.
