Abstract
Using leaves from annual branches of grape cultiver Beta as material,the change in hydrogen peroxide(H2O2) and abscisic acid(ABA) content in leaves of Beta under low temperature were measured,the effects of exogenous H2O2 and ascorbic acid(AsA) on endogenous ABA content were studied meanwhile.The results showed that the H2O2 and ABA content in leaves of Beta under low temperature increased firstly then decreased,H2O2 and ABA burst can be seen,the burst of H2O2 was more early than ABA.Exogenous H2O2 promoted the increase of ABA content,on the other hand,AsA had inhibitory effect on the increase of ABA content,these results indicated that H2O2 and ABA all participated in the response of Beta to low temperature and H2O2 lies in the upstream of ABA.

Claim · model-written summary
The authors conclude that H2O2 and ABA both participate in the response of grape to low temperature and that H2O2 lies upstream of ABA.
