Abstract In order to study of the effect of substrates on vegetative and ecophysiological characteristics of coleus plant, coleus cuttings containing two leaves were planted in perlite, cocopeat, peatmoss, compost, 50% perlite + 50% cocopeat, 50% perlite + 50% peatmoss, 50% perlite + 50% compost, 5% cocopeat+50% peatmoss, 50% cocopeat + 50% compost and 50% peatmoss + 50% compost with four repl...
A pot experiment was conducted to evaluate the effect of synthetic wastewater containing various concentrations of cadmium and chromium on Eucalyptus camaldulensis. Six month-old seedlings of E. camaldulensis were treated with Cd (II) and Cr (VI) for 18 months. Treatments were; T0: (Tap water, control), T1: 0.05 +1.0 mg L, T2: 0.10+2.0 mg L, T3: 0.20+4.0 mg L and T4: 0.40+8.0 mg L of Cd and Cr ...
The aim of this research was evaluate the seedling behavior of among Pistacia species can be used as rootstock in pistachio. Differences in stem diameter were observed among the species. The thickest stems were developed by P. atlantica (5.67 mm), P. vera cv. ‘Qazvini’ (25.47mm) and ‘Badami-e-Riz-e-Zarand’ (5.13 mm) whereas the thinnest stems were measured in P. atlantica subsp. kurdica (3.48 m...
