【摘要】 豆科牧草既是重要的饲料作物,又在土壤改良、水土保持,以及生态环境保护方面发挥着积极作用。随着分子生物学和植物转化技术的发展和改进,通过基因工程技术对豆科牧草进行改良和培育已成为可能。本文就近几年来基因工程技术在各种豆科牧草的高产、抗病虫害、抗逆及品质改良等方面的研究进展进行了较全面的综述。更多还原

【Abstract】 As important forage crops,legume forage plants can play an important role in improving natural environment, ma-intenins water and soil. With development of molecular biology and improvement of plant transformation techniques, molecular breeding of legume forage plants by biotechnology is possible. This review summarized recent progress on improvement of several forage crops,including improvement of nutrient quality,increase of biomass,enhancement of the assimilation and efficient absorb of nutrient element,and enhancement of abiotic and biotic stress resistance.更多还原
