Comparisons on seedlings growth traits of five alder genus species
Seedlings period growth traits of three exotic alder including Alnus glutinosa,A.cordata,A.nitida and two domestic alder,A.formosana and A.cremastogyne were studied with comparative-method.The growth traits including thousand kernels weight,germination rate and germination potential of seed,relative content of chlorophyll (SPAD),photosynthetic traits,rooting parameters and biomass among the five tree species were compared,and the affected factors for seedlings growth were studied with principal component analysis.The results show that among five alders,the plant pattern of A.glutinosa was the best,its biomass was the maximum;the root system,total leaf area of per plant and SPAD were the main factors affected the biomass composition of A.glutinosa.So,A.glutinosa has certain application potential in forestry production.
