研究多年生禾本科牧草的发育生物学,对于制定和正确运用旨在提高该作物产量的各种农业技术措施方面,以及对于揭明决定植物越冬性的规律性方面,都具有重大的意义,因为大家都知道,多年生禾本科牧草对於冬季的不良条件,具有惊人的适应性。植物阶段发育理论是揭明多年生禾本科牧草发育特性的基础。在许多学者的著作中,企图将禾本科谷类作物的阶段发育的某些方面,机械地搬用到多年生牧草的发育上来。例如,根据А.Ф.切皮考娃(А.Ф.
Studying the developmental biology of perennial grasses is of great importance in formulating and correctly applying the various agro-technical measures aimed at increasing the crop yield and in revealing the regularities that determine plant overwintering as everyone All know that perennial grasses have amazing adaptability to winter conditions. The theory of plant stage development is the basis for revealing the developmental characteristics of perennial grasses. In the writings of many scholars, attempts are made to mechanically transfer certain aspects of the stage development of gramineous cereal crops to the development of perennial grasses. For example, according to А.Ф. Cecilia Ka (А.Ф.
