Abstract

Three antioxidants of 0.1% concentration were used to pretreat for different time on rice in vitro embryos to study their effects on inhibiting callus browning of two quality varieties of Indica rice,Guihuazhan and Youzhan No.8.The optimum pretreated times of citric acid were 18 h and 24 h,vitamin C and polyvinylpyrrolidone (PVP) was 3 h.Citric acid had the greatest effect on inhibiting callus browning,but it would reduce callus induction at the same time.Vitamin C not only inhibited callus browning but also improved callus induction and callus growing.PVP had general effect on inhibiting callus from browning.
