草坪植物持绿性及相关研究进展

Advances in Stay-green Characteristics in Turfgrass and Related Research

草坪是景观绿化的主要组成元素,具有重要的生态功能和美学价值。草坪草色泽和持绿性是衡量草坪质量的重要指标,选择和培育绿期长、叶色浓绿的草坪草品种对草坪生产有重要意义。对国内外植物持绿性的功能和机理、持绿功能基因调控草坪草色泽的机制研究进展进行系统综述,并提出了研究建议。

Turf is the main component of landscape greening,which has important ecological function and aesthetic value.The color and greenness of turfgrass are important indicators to measure the quality of turf.Therefore,it is necessary for turf production and application to select and cultivate new turfgrass cultivars with long green period and dark green leaves.In this paper,we systematically reviewed the research on the function and mechanism of plant stay-green traits at home and abroad,and the mechanism of stay-green function genes regulating turfgrass color,and put forward some suggestions for improving the stay-green trait of turfgrass.
