不同种源雷公藤叶片营养元素及甲素含量的差异分析
Variance Analyses of Nutrient Elements and Tripolide Content in Leaves of Different Tripterygium wilfordii Hook.f.Provenances
摘要
Abstract
In this study,we analyzed the difference in nutrients and tripolide (TR) contents in leaves of Tripterygium wilfordii Hook.f.among 13 different provenances,which were planted in the same environment,in order to reveal the correlations between geographical variability,nutrients elements and TR contents among different provenances.The results showed as following:1) Among the 13 provenances,there are 8 provenances (3A,36A,32,4,X37,J73,90,94) with nutrient elements in the leaves in the order of C>K>N>Mg>Ca>P,and the other 5 provenances with nutrient elements (8,20A,59,86,97) in the leaves in the order of C>K>N>Mg>P>Ca.The contents of limiting elements,N and P,were significantly lower than the national averages,which showed that there was serious restriction of N and P in this area.2) There was significant difference between different provenances in the nutrient elements and TR contents in leaves,with provenance 94 having the highest content of TR (10.98 mg/g).Meanwhile,the degree of variation in the nutrient elements and TR contents in leaves is different,where the amplitude of Mg is the biggest (CV=40.86%),but N is the smallest (CV=8.61%).3) The correlation analysis of nutrient elements and TR indicated that the correlations between Mg and C and between Mg and Ca were significantly positive,but K and Ca,C and N,and Mg and N were negatively correlated.C has a negative and P has a positive correlation with TR.Comprehensive analysis of 13 provenances demonstrated that 13A,4,and X37 were affected by N and P double restriction,but the stable N/P ratios indicated that the three provenances′ adaptation to the environment was stronger than those of the others.In addition,the TR content of X37 (8.81 mg/g) was higher than that of the 13A and 4 provenances.Through comparing the difference in nutrient elements and TR content in leaves and geographic variation regularity among different provenances,this study would provide foundation for selecting appropriate T.wilfordii Hook.f.geographical provenances,which can be cultivated in Fujian forests.关键词
