Method of increasing growth of lateral roots of Malus hupehensis

Abstract

The invention discloses a method of increasing growth of lateral roots of Malus hupehensis. The method of increasing growth of lateral roots of Malus hupehensis includes the steps: after storing seeds of Malus hupehensis in sand for one month, planting the seeds of Malus hupehensis in a nutrition pot; selecting 8-10 leaves and 60-days old and insect-disease-free seedlings of Malus hupehensis, and taking the seedlings of Malus hupehensis away from the nutrition pot, rinsing the matrix by means of clean water, and transplanting the seedlings of Malus hupehensis to a greenhouse; transplanting the seedlings of Malus hupehensis to 1 / 2Hoagland water planting nutrient solution for seedling recovering for half a month, and exchanging the nutrient solution once a week; and performing BR (brassinosteroid) processing, wherein the BR processing concentration is 0.5mg / l, normally managing after one week of processing, exchanging the nutrient solution once a week, and cultivating for one month. For the method of increasing growth of lateral roots of Malus hupehensis, the BR processing increases the number of roots, the length of roots, the surface area of roots, the volume of roots, the height of plants, and the thickness of stems of the seedlings of Malus hupehensis. In a word, the RB processing is conductive to growth of lateral roots, and especially increases growth of fine roots. The method of increasing growth of lateral roots of Malus hupehensis can provide certain theoretical basis for growth of lateral roots of apple, and has important meaning for guiding practical production.

Description

technical field [0001] The invention belongs to the technical field of planting economic crops, and in particular relates to a method for increasing the development of lateral roots of Pingyi sweet tea. Background technique [0002] The plant root system is an important organ for absorbing water and nutrients, and the lateral roots are an important part of the plant root system. There is a long history of research on lateral root development, most of which focus on the herbaceous plant Arabidopsis (Meyerowitz, 2001). However, in woody plants, especially in economic crops, research on lateral root and root system development lags behind , which to a certain extent has caused difficulties in carrying out practical work such as breeding of economic crops targeting the excellent trait of root system. The woody plant apple and the herbaceous plant Arabidopsis have great differences in the root cell structure. Although the development process is relatively similar, they may have ...
