摘　　要：BMR(褐色中脉)基因型饲草高粱因低木质素含量、高消化率而广泛受到重视,但这类品种在生产中往往更易发生倒伏。为进一步明确BMR(褐色中脉)基因型饲草高粱茎秆特征与抗倒性关系,本文从与茎秆相关的农艺性状、力学特性、解剖结构、化学组成等方面综述了BMR基因型饲草高粱茎秆特征与抗倒性关系的研究进展,旨为进一步研究BMR基因型饲草高粱茎秆特征与抗倒性关系,改良BMR基因型饲草高粱的抗倒性提供理论参考。The BMR(brown midrib)genotype forage Sorghum is widely attached importance due to its low lignin content and high digestibility,but these varieties tend to be more prone to lodging in production.In order to further clear the relationships of stems and lodging resistance in the BMR genotype forage Sorghum,this paper reviewed the research progress on the relationship between stem characteristics and lodging resistance from the agronomic traits,mechanical characteristics,anatomical structure and chemical composition of the BMR genotype forage Sorghum.Which aiming to provide theoretical reference for further studying the relationship between stem traits and lodging resistance and improving the lodging resistance for BMR genotype forage Sorghum.
