秦岭壳斗科四种植物种子雨组成及其动态变化
Composition and dynamics of seed rain in four species of Fagaceae in Qinling Mountains
摘要
Abstract
The composition and dynamic of seed rain is a key stage in plant regeneration.From August to De-cember in 2011 and 2012,the seed rain of four Fagaceae species(Castanea mollissima,Quercus variabilis,Q. aliena,Q.glandulifera )were investigated in the Foping Nature Reserve in southern slope of Qinling Mountains.The results were as follows:(1)The seed rain of these four species began in the middle of August, and finished in the end of November.The fall peaks of seed rain were in late September to middle October,and the fall peak of each seed rain category in C.mollissima was earlier than other three species;(2)Whether in 2011 or 2012,there were significant differences in each seed rain category dynamics among Q.variabilis,Q. aliena and Q.glandulifera,but each seed rain category dynamic in C.mollissima was not significantly differ-ent;(3)There were significant differences in seed rain dynamics of these four species between years,and the seed rain density of each category was higher in 2011 than in 2012(except for Q.variabilis).This result con-jectured that 2011 might be the relatively mast seeding year for these species.关键词
