摘  要：
许多生态因子可影响作物缺铁失绿,例如:介质缺铁,高pH,多HCO_3、CO_2、水分,重金属元素盈亏,某些常量元素过多或形态的差异,以及光照,温度等。本文根据最近研究进展,对各种因子的特点及其影响失绿的作用条件加以阐述。

ADVANCES IN THE RESEARCH OF IRON CHLOROSIS OF APPLE PLANTSⅠ.The Influence of Ecological Factors on the Severity of Chlorosis

摘  要：
Many environmental factors influenced the occurrence or severity of chlorosis. Iron stress was known as the main factor inducing chlorosis. High levels of HCO_3, pH, CO_2, Cu, Mn, and/or Zn under low iron condition increased the severity of chlorotic symptoms. The presence of ethylene in the medium also caused chlorosis. High potassium with high levels of HCO_3 strengthened the degree of the disorder, but there was no chlorotic effect without HCO_3. High chelator to iron ratio performed advantages for correcting the symptom and stimulating the transport of iron in the plant, High phosphoroas and NO_3-N sometimes intensified the severity of symptoms, but the former was proved to be a mild factor. Light quantity showed some effect on the occurrence of chlorosis.
