In order to improve quantitative and qualitative properties and vase life of rose cv. Dolcvita, an experiment was conducted in a randomized complete blocks design with ten treatments and three replications in a hydroponic greenhouse adjacent to Yasouj city, Iran. Treatments included control, spermidine (0.5, 1 and 1.5 mM), calcium sulfate (2.5 and 5 mM), spermidine 0.5 mM+ calcium sulfate 2.5 m...

Today, the use of allometric relations for easy, non-destructive, low cost and fast estimation of tree biomass is widely used. The aim of this study was to estimate the stem biomass of Pupulus. caspica and Pupulus. alba 57.58 seedlings. First, 45 cuttings from both fast-growing tree species were selected and planted in a randomized complete block design with three replications in the lands of C...

In order to study the effect of CPPU growth regulator on qualitative characteristics of cut rose (Rosa hybrida cv. Avalanche), an experiment was performed as factorial, based on a completely randomized design, with four replications. In this experiment, the first factor included four concentrations of CPPU (0, 25, 50 and 100 mg/L) and the second factor was two application positions of CPPU (on ...
