Abstract:
Using ‘Korla’ fragrant pear as material，the variations of N,P,K,Ca,Mg content in the leaves and fruits of fragrant pear were investigated during the development.The results showed that the contents of P，K，Ca presented downward trend and the content of Mg was on the rise in the leaves of fragrant pear.But the content of N changed largely.The prominent negative correlation were presented between the content of P with Mg，and the negative correlation were presented between the contents of K and Mg.In the fruits of fragrant pear，the contents of N,P,K,Ca,Mg reduced gradually with fruit development.The prominent positive correlation were presented between the contents of P,K,Ca,Mg and the content of N，the positive correlation were presented between the content of P and K content，the prominent positive correlation were presented between the content of K and Ca，and the prominent positive correlation were presented between the content of Ca and the content of Mg.
