Abstract

The invention discloses a chemical regulation method for increasing the quality and resistance of sandalwood seedlings and belongs to the field of plant growth regulation. The chemical regulation method includes: selecting and preparing a growth regulation agent, isolating host plants, applying the growth regulation agent, performing seedling management and the like. The chemical regulation methodhas the advantages that the ground diameter and canopy growth of the sandalwood seedlings can be promoted evidently, biomass accumulation is increased, seedling quality indexes (QI) are increased, the synthesizing of leaf photosynthetic pigment is promoted, the content of soluble sugar and soluble protein in leaves is increased, the net photosynthetic rate of the leaves is enhanced, the activityof antioxidant enzymes (catalase, peroxidase and superoxide dismutase) is increased evidently, membrane lipid peroxidation is reduced, stress resistance is enhanced, and economic benefits are increased to the maximum degree; the method is simple to operate, quick in action, practicable and the like.

Description

technical field

[0001] The invention belongs to the field of plant growth regulation, and in particular relates to a chemical regulation method for improving the quality and resistance of sandalwood seedlings. Background technique

[0002] Sandalwood (Santalum album L.) is a root semi-parasitic evergreen small tree of the genus Sandalwood in the family Sandalaceae. Perfume essence, essential oil, medicine and other industries are widely used, and its main economic value lies in the heartwood with aromatic smell and the sandalwood essential oil extracted from the heartwood. my country's mainland began to introduce sandalwood as early as 1962 (Li Yinglan, 2003). After years of repeated research and practice, it has achieved success and formed a heartwood with economic value and sandalwood essential oil that meets international quality standards (Liu Xiaojin et al. , 2013; 2016a).

[0003] The cultivation of strong seedlings is one of the most important links throughout the en...
