This trial studied the effects of prometrgne on the young shoot growth,leaf chlorophyll content,MDA content and electrical conductivity of membrane of Ziziphus jujuba Mill.

This trial studied the effects of pendimethalin on the young shoot growth,leaf chlorophyll content,MDA content and conductance rate of Zizphus jujuba Mill.

In order to study the effects of supplemental lighting with different light quality on the growth of greenhouse grape,2-year-old potted jinxiu grape plants growing in a solar greenhouse were used to evaluate shoot growth dynamic after 30d supplemental lighting(4 h each day) with red,blue and ultraviolet(UVA and UVB) light,which started to work from leaf unfolding stage.

Growth dynamics, shoot growth vigor, fruit setting, and yield of sea buckthom cultivars from Russia, Mongolia and China(ck), which are growing in the same orchard, were studied.

The experiment studied different plant growth regulator to shoot growth relation of leaves and water, photosynthesis , transpire rete and resist oxidize ability of potted or field plant grapevine (Vitis Vinifera) small tree, during water stress period and detached leaves to natural drying in air was effect.

When NaHSO 3 is sprayed three times to the leaves of the peach tree at stage of fruit expanding, it can raise fruit set percentage and single fruit weight and promote new shoot growth, improve quality.
