陕北黄土丘陵区6种植物冠层种子库的初步研究

Canopy Seed Bank of Six Species in the Hilly-gullied Loess Plateau of Northern Shaanxi

  • 摘要: 对陕北黄土丘陵区猪毛蒿(Artemisia scoparia)、铁杆蒿(Artemisia gmelinii)、茭蒿(Artemisia giraldii)、杠柳(Periploca sepium)、狼牙刺(Sophora viciifolia)和黄刺玫(Rosa xanthina)6种植物不同时期的冠层种子宿存量进行了调查。结果显示,6种植物均有不同程度的植冠种子宿存量,翌年4月,黄刺玫的宿存量可达57.60%,狼牙刺的宿存量达31.56%,杠柳的宿存量为6.30%,铁杆蒿的宿存量为2.42%,猪毛蒿的宿存量为1.86%,茭蒿的宿存量为1.16%。猪毛蒿、铁杆蒿、茭蒿、黄刺玫的种子宿存时间可长达7个月之久,狼牙刺、杠柳的宿存时间为5~7个月。

     

    Abstract: This research investigated the canopy seed bank size of six species(Artemisia scoparia,Artemisia gmelinii,Artemisia giraldii,Sophora viciifolia,Periploca sepium,and Rosa xanthina) during different times of the year.The results showed that the six species have canopy seeds more or less,with 57.60%,31.56%,6.30%,2.42%,1.86%,and 1.16% seeds from Rosa xanthina,Sophora viciifolia,Periploca sepium,Artemisia gmelinii,Artemisia scoparia,and Artemisia giraldii storing in canopy until April of the following year,respectively.Artemisia scoparia,Artemisia gmelinii,Artemisia giraldii,and Rosa xanthina can maintain seeds for longer(more than 7 months) than Sophora viciifolia and Periploca sepium(5-7 months).
