تاثیر تیمار قبل و پس از برداست منابع و مقادیر مختلف کلسیم بر طول عمر گل شاخه بریده رز رقم ایلوانا

Abstract : Calcium has an important role in postharvest and that's transport in plant has some problems, in This experiment conducted in National Research station of Ornamental Plant (Mahallat) and Agricultural Research Center ofsafiabad (Dezful) since 1382 for 3 years, the effects of different amounts and sources of ca and different Appliance Methods of that in Per and Post harvest of Rose cv.Ilona studied in a Randomized complete blocks as factorial Design. Experiment was contains two separate stage at first, flowers harvested from the plants, which sprayed by 0, 0.3, 0.6, g/lit Ca from calcium chloride. Calcium Nitrate and calcium chelat as different sources of calcium. After that flowers putted 3h in different solutions, contains : 1-distiled water (control) 2- water +CaCl2 ( 2 mmol Ca) 3- water + Ca(No3)2 (2 mmol Ca) 4- 8 HQC(250 ppm) + sucrose %4+ CaCl2 = (2mmol Ca) 5- 8 HQC(250 ppm) + sucrose %4+Ca(No3)2 (2mmol Ca) 6- 8 HQC(250 ppm) + sucrose %4 For second experiment flowers harvested from the plants, which sprayed by 0, 0.3, 0.6, g/lit Ca from calcium chloride. Calcium Nitrate and calcium chelat as different sources of calcium, next putted 3h in two solution contains: 1 .distiled water (control) 2- 8 HQC(250 ppm)+ sucrose %4 After that simultaneously sprayed by 0, 0.3, 0.6 g/lit Ca from different sources . After this treatments, evaluated vase life of cut Roses A. Results in Mahallat: The first experiment Resulted that spraying by 0.3 g/lit Calcium chelat and 0.6 g/lit CaCl2 have the most and 0.6 g/lit calcium chelat had sprayed by 0.6 g/lit CaCl2 have the best quality of flowers and leaves. Using CaClz and Ca(NC> 3) 2 2 mmol /lit as vase solution have the most effect on vase life. Effect of spraying treatments on quality and vase life w
