This experiment was conducted to study the effects of application of partial root zone drying technique on quantitative and qualitative characteristics of strawberry (Fragaria ananassa cv. Selva). The experiment was arranged as randomized complete blocks design with five treatments and four replications. One week after planting the seedlings, different irrigation regimes including FC: FC (moist...
in this research we have studied the effect of some transition-metals (cu, ag and au) substitutions on two-electron reduction potential of flavins by application of dft method. all geometries have been optimized at blyp level of theory and “6-31+g** + lanl2dz” mixed basis set. the frequency job at the same method and basis sets has been performed to obtain gibbs free energy of compounds. it h...
This experiment was conducted to study the effect of cocopeat: perlite medium with three ratios (v/v) (1:1, 3:1 and 1:3) on some vegetative, flowering and biochemical parameters of two gladiolus cultivars (Strong and White) under soilless conditions in 2016. Data indicated that most vegetative parameters expressed as plant height, leaf number and leaf area, flowering parameter such as spike eme...
