Effects of Formulated Fertilizer Synergist on Abscisic Acid Accumulation, 
Proline Content and Photosynthetic Characteristics of Rice under Drought

摘要/Abstract

摘要： To investigate the effects of formulated fertilizer synergist on the drought tolerance in rice, pot experiment was
conducted to analyze the photosynthetic characteristics and the accumulation of abscisic acid (ABA) and proline in
middle-season rice variety Peiliangyou 93. The synergist could improve the net photosynthetic rate, and coordination
between the water loss and the CO₂ absorption as well as reduce the harmful effect on photosynthetic process under drought
conditions. Under drought, the ABA accumulated massively both in roots and leaves, while the ABA content in roots was far
higher than that in leaves. The results indicate that synergist could increase the ABA accumulation, but reduce the proline
accumulation in rice plant under drought.
