possible role of nitric oxide in budbreak in pistachio (pistaciavera l.): a novel method

In this study, one product derived from sodium nitroprusside (snp) was used as a nitric oxide (no) donor and evaluated as a stimulant bud break agent of ahmad-aghaei pistachio. trees were treated by snp 0, 0.30, 0.60, 0.90 and 1.20 mm in two stages (4 and 8 weeks before normal budbreak (february 1 and january 1, respectively)) with a factorial experiment in a randomized complete block design with four replications. results showed that snp treatment hastened the bud break date and increased the yield. snp decreased the misshapen nuts and empty and non-splitting shells compared with the control treatment. in both on and off years, the effect of snp was greatly dependent on both times of application and concentrations used. results showed that exogenous application of this compound, especially during the second application, increased splitting shell nut, number of nuts per cluster, number of nuts per ounce, leaf area, shoot length, and shoot diameterin both on and off years. no limitations were encountered. the results of this study might apply to pistachio and temperate fruit-growing regions with a mild winter. because in mild winter, pistachio trees’ chilling requirements are not resolved, and this substance helps with this deficiency.
