New use of sodium hydrosulfide for promoting plant root morphogenesis

Abstract

The invention relates to a new application of sodium hydrosulfide for promoting the morphogenesis of plant roots, namely, the application is that the sodium hydrosulfide is taken as root stimulate to promote the morphogenesis of side roots and adventitious roots of the seedling of the plant and the morphogenesis of the adventitious roots of cutting branches of the plant. The sodium hydrosulfide has obvious root-promoting effect to the seedlings of the plant such as rapes, mung beans, soybeans, cucumbers and the like, the hypocotyledonary axis of the cut segment thereof and the cutting branches of the plant such as willow branches, peach branches, grapes, batatas and the like, promotes the formation and growth of the side roots and the adventitious roots of the plant, enhances the water absorbing capacity of the plant, maintains the water balance in the body of the plant, reduces membrane lipid overoxidation damage of the hypocotyledonary axis of the cut segment and the cutting branches, maintains the relative stability of membrane structure of the explant and promotes the growth and propagation of the plant. The root-promoting agent can be used for growing roots of various plant seedlings, the hypocotyledonary axis of the cut segment and the cutting branches and is applicable to the root-promoting effect of promoting and culturing the seedlings of transplanting and cutting and the like, in the agriculture, forestry and gardening.

Description

1. Technical field [0001] The present invention relates to a new use of a known compound, specifically a new use of sodium hydrosulfide (NaHS) to promote plant root morphogenesis. 2. Background technology [0002] There are two kinds of roots in plants, one is the embryonic root derived from the embryo that forms a strong root system in the plant; the other is the adventitious root, which does not follow the normal sequence and appears in abnormal positions such as stems and leaves. The adventitious roots formed on non-root tissues such as plant tender stems, branches, aerial stems, underground stems, and leaves have two ways of occurrence. The way of forming adventitious roots directly from cuttings is direct generation; and from cuttings, calluses are first produced, and then The formation of quasi-meristems and the final generation of adventitious root primordia are indirect. Plants have great differences in the difficulty of rooting depending on the way in which adventi...
