果树缺铁性黄化植株诊断方法的研究进展

Advance in Research on Diagnose of Iron-deficient Chlorosis in Fruits

该文主要评述了果树缺铁性黄化诊断中叶分析的不足和花分析的可行性。通过对国内外文献分析可知,叶分析存在滞后性和矛盾性两方面不足,而花分析能更好地了解果树铁营养状况,比叶分析具有一定的优越性。今后应加强花诊断指标和采样部位的研究。

The present paper discussed the shortcoming of leaf analysis and the probability of flower analysis as a tool to diagnosis Fe nutritional status of fruit trees.Througout reviewing lots of literatures,Leaf analysis has shortcoming in two sides:one hand is that the sampling time is lag;the other hand is that Fe-chlorotic leaves may have considerable concentrations of total Fe per dry matter(the 'Fe-chlorosis paradox'),sometimes higher than green leaves.flower analysis is superior to leaf analysis in fruits,we should concentrate on the research of the sampling site and flower analysis index.
