The Influence of Water Stress on cAMP Content in Leaves and Young Ears of Maize

Hu Anchang;Shen Xiuying;Dai Junying;Zhao Rundong;Zheng Bo (Shenyang Agricultural University)  
The experiments on variation of cAMP contents in leaves, young tassels and ears in maize under stress were conducted in Shenyang. The results indicated that cAMP content in full extension leaves varied with growth stages. It rearched the peak value at floret differentiation and decreased with aging of leaves. The cAMP contents were higher in fast growing organs, such as very young leaves,tassels and ears. Drought resulted in decrease of cAMP content. The tendency of changes was that the higher the cAMP content, the greater it decreascd with water stress. Ca~(2+) and BR (brassinolide) had effects on increasing cAMP content in leaves, and the changes of ATP content were similar to that of cAMP.
