亚麻耐盐碱性研究进展
Research Progress on Salt and Alkali Tolerance of Flax
摘要
Abstract
Soil salinization seriously threatens agricultural production.Flax,as an important economic crop,its salt-tolerant and alkali-tolerant characteristics have attracted much attention.This research aims to comprehensively review the research progress of flax's tolerance to salt and alkali,providing a theoretical basis for improving the adaptability of flax in saline-alkali soil and promoting the development and utilization of saline-alkali land.By consulting relevant domestic and foreign literature,a comprehensive analysis was conducted on aspects such as the characteristic performance,mechanism research,germplasm resource screening,breeding progress of flax's tolerance to salt and alkali,and practical application in planting in saline-alkali land.The response mechanism of flax to salt-alkali stress and the ways to enhance its salt and alkali tolerance were deeply discussed.Some flax varieties can grow in mild to moderate saline-alkali environments,but the growth rate slows down compared to normal soil conditions.With the increase of salinity and alkalinity,indicators such as plant height,branch number,and biomass of flax decrease significantly.Under salt-alkali stress,the expression levels of genes related to flax's salt and alkali tolerance change significantly.Different varieties of flax have significant differences in salt and alkali tolerance.Currently,several flax varieties with strong salt and alkali tolerance have been identified,and these varieties have greater potential in planting in saline-alkali land.Some progress has been made in the research of flax's salt and alkali tolerance,but it still faces many challenges.The mechanism of flax's salt and alkali tolerance is not yet fully clear,breeding techniques need to be further improved,and environmental factors have a great influence on flax's salt and alkali tolerance.In the future,it is necessary to conduct in-depth research on the salt and alkali tolerance mechanism,innovate breeding techniques,strengthen multidisciplinary cooperation,increase the promotion and application of salt and alkali-tolerant flax varieties,to achieve efficient planting of flax in saline-alkali land and the sustainable development and utilization of saline-alkali land,and contribute to the sustainable development of agriculture.关键词
