嫁接提高园艺作物耐热性的研究进展
The research progress on improving the heat resistance of horticultural crops by grafting
摘要
Abstract
As a long and emerging asexual reproduction technology, grafting has been widely used in propagation, new cultivar breeding and quality improvement of horticultural crops. This article focused on the application of grafting technology to improve the heat resistance of horticultural crops and reviewed the latest research progress on the mechanism of improving heat resistance by grafting. After grafting, the root activity, photosynthetic rate and enzyme activity of the leaves were enhanced obviously. The contents of endogenous hormones in different parts of the plant were changed significantly. Horizontal gene transfer (HGT) and RNA long distance transport were happened to modify gene expression. At the same time, the problems that still need to be solved and the development prospect of grafting technology were also discussed. Popularizing grafting technology and studying the mechanism of enhancing plant heat resistance by grafting will greatly promote the cultivation and breeding of horticultural crops.关键词
