The correlations of TI and TO with weather factors were similar in different years,differing only in 2012(Table 4),and were not statistically significant in 2012.Accordingly,the overall results of the four years were used.It was concluded that TI,TO,and TP were negatively correlated with AT15,and MDT(P<0.05)but positively correlated with DTR and HS(P<0.01;Table 4)on a national scale.TO was negatively correlated with RF(P<0.01).Neither TI nor TP showed a significant correlation with RF.TS was negatively correlated with MDT(P<0.05)and positively correlated with RF(P<0.01),and showed no significant correlation with AT15,HS,and DTR.Similar to TI,daidzin and genistin were also negatively correlated with AT15,and MDT(P<0.01)but positively correlated with HS and DTR(P<0.01;Table 5).MD showed a positive correlation with HS and DTR(P<0.05).Sucrose and raffinose showed a negative correlation with MDT and RF(P<0.05),and a positive correlation with HS and DTR(P<0.01;Table 5),which was consistent with TO.Raffinose content was negatively correlated with AT15(P<0.05),whereas no such correlation was observed for sucrose.PC and PI showed a relationship that was similar to that between TP and weather factors.They were negatively correlated with AT15and MDT(P<0.01)but positively correlated with DTR and HS(P<0.05).In contrast,PE showed a positive correlation with AT15and MDT(P<0.01)but a negative correlation with HS(P<0.05).Consistent with TS,saponin I and saponinαg showed negative relationships with MDT(P<0.05);inconsistently,they showed a significant negative correlation with RF(P<0.01).saponin I,saponin II,and saponinαg were positively correlated with DTR and HS(P<0.01),whereas TS showed no relationship with DTR and HS.Like TS,saponinβg and saponinβαshowed significantly positive correlations with RF(P<0.01);however,they were not correlated with AT15,MDT,or DTR.
