摘 要
通過室內窗邊培養和黑暗培養粵選1號匍匐翦股穎及矮生品系1613-01、1613-02、1613-4、1613-5、1613-6、1614-3、3603、3605-2，測定株高、根長、葉片長、分蘗數、生物量、葉片存活天數、葉片枯黃率、葉片老化指數等指標，以自然光照培養材料為對照，并進行草坪質量、草毯室內應用及草毯草種評分。結果說明，室內窗邊培養和黑暗培養，匍匐翦股穎表現出徒長趨勢，葉片增長、根短、分蘗少；葉色淺、枯黃，老化；生物量減少等。窗邊培養的矮生品系1613-02、1613-4、1613-5、3603與粵選1號匍匐翦股穎相比，其株高、根長、生物量、葉片枯黃率、葉片老化指數變化值較�。缓诎蹬囵B的矮生品系1613-02、1613-4、1613-5、3603與粵選1號匍匐翦股穎相比，其株高、生物量、葉片老化指數變化值較小；匍匐翦股穎矮生品系1613-02在室內生長速度慢，植株存活能力強、并且具備較高的草坪和草毯質量，表現出最好的室內草毯應用潛力。

eva luation of Shade-tolerance to Agrostis stolonifera Dwarf Strains
Abstract：The plant height, the length of roots and leaf, the number of tiller, biomass, survival time of leaf, rate of yellow leaf, leaf senescence index of Yuexuan No. 1 and new Agrostis stolonifera dwarf stain 1613-01、1613-02、1613-4、1613-5、1613-6、1614-3、3603、3605-2 were determined by cultivated beside windows indoor and in dark indoor. The results indicated that when cultivated beside windows indoor and in dark indoor, Agrostis stolonifera appeared a trend of excessive growth, and the length of leaf increased, the length of roots shortened, the number of tiller reduced, the color of leaf became light and yellow, the leaf became senescence, and the biomass was reduced, etc. Compared with Yuexuan No.1, the change of plant height, the length of roots, biomass, rate of yellow leaf, leaf senescence index of Agrostis stolonifera dwarf strain 1613-02、1613-4、1613-5、3603 cultivated beside windows indoor were less. By cultivated in dark indoor, compared with Yue xuan No. 1, the change of plant height, biomass, rate of yellow leaf, leaf senescence index of Agrostis stolonifera dwarf strain 1613-4、1613-5、3603、3605-2 were less too. When Agrostis stolonifera dwarf strain 1613-02 was cultivated indoor, the growing speed was slow, and the survivability was strong. It was also became an excellent quality grass blanket, and expressed a best potential of grass blanket indoor application.
Key words：Agrostis stolonifera; dwarf strain; grass blanket; shade-tolerance
