牧草种子生产中落粒性的影响因素与防控技术

摘要

Sh attering is one of the main restraint factors in forage seed production, which often caused serious loss of the seed production of many quality forage containing Bromue inermis、Agropyron cristatum、 Elymus sibiricus、 Festuca arundinacea、 Poa pretensis、 Brachiaria ruziziensis. This paper is mainly analyzed and disscussed the influence factors of seed shattering, its influence on seed production and controlling measures on seed shattering, which can supply the strong reference for reducing seed shattering in future forage seed production.%落粒性是牧草种子生产中的关键制约因素，通常造成无芒雀麦(Bromue inermis)、冰草(Agropyron cristatum)、老芒麦(Elymus sibiricus)、高羊茅(Festuca arundinacea)、草地早熟禾(Poa pretensis)、路氏臂形草(Brachiaria ruziziensis)等优良牧草种子严重减产。本文重点阐述种子生产中影响落粒性的因素，种子落粒性对种子生产的影响，相关减少种子落粒性的研究进展及措施，为今后在生产中降低牧草种子落粒性提供参考。
