[Effects of exogenous nitric oxide donor on germination and activities of hydrolytic enzymes in wheat seed under osmotic stress].
Zhi Wu Sheng Li Yu Fen Zi Sheng Wu Xue Xue Bao. 2005 Jun; 31(3):241-6.ZW

Abstract

Results in this paper showed that the effect of nitric oxide (NO) donor, sodium nitroprusside (SNP), which could promote the germination of wheat seeds under osmotic stress, was through enhancing imbibition using water content determination and imbibition analysis of wheat seed. SNP could also enhance amylase isozyme I activities, accelerate the liquefaction of endosperms, while have no effect on esterase. Moreover, SNP could strongly increase the sugars, such as the fructose, glucose and sucrose contents in wheat seeds during early germination (12 h) under normal conditions. When the seeds were treated with SNP with or without PTIO, an NO scavenger, and different exogenous sugars, i.e. fructose, glucose and sucrose, it was found that these sugars might activate amylase isozyme I activity mediated by the signal molecule NO to start the early stage of germination.
