Wang Yu-xiang;Zhang Bo;Key Laboratony of Grassland Resource and Ecology of Xingjiang,Pratacultural Institute of Xinjiang Agricultural University;  
To understand tripping phenomenon and reproductive characteristics of Xinjiang Trifolium,flowering habit,pollen spreading time and the influence of different mating pattern on reproductive characteristic were studied.The results as followed:1)flower from budding to wilting maintained 50~52h,pollen display belongs to keel valvular insufficiency;2)the pistil stigma crazed when wing petal grow to 1/2of flag petal;3)the podding rate of Trifoliumfrom Changji desert steppe in the autonomous selfing was highest(98.61%);the podding rate of Trifoliumfrom Urumqi Nanshan mountain meadow under homologous strain cross-pollination was the highest(100%);the podding rate of Hutubi Trifoliumunder forest belt with free pollination was the lowest(96.30%).The results of this study can provide some references for further study on breeding system and reproductive biology of Trifolium repens.
