Study of Morphological Characteristics of Caucasian Hackberry Irrigated with Wastewater of Kashafrood River

Abstract

Phytoremediation or the use of plants to reduce pollution, in addition to the low cost and usability treating a wide range of eco cognition is considered. In order to evaluate the effect of wastewater Kashafrood on Celtis caucasica Willd seedlings, the research was conducted based on completely randomized design in summer season. On the (a common method of irrigation nursery two days a time by irrigation of 150 mL day-1), the morphological-related parameters were measured. Traits were measured including: height, diameter, number of leaves, leaf area, shoot and root length, dry weight of roots, stem and leaf and ratios of root to shoot, leaf to shoot, leaf area, specific leaf area, leaf weight, freshly and number of root. Results in Principal Component Analysis (PCA) showed that in PC1 in wastewater stress reduced root length and increase dry weight root, total dry weight, freshly and number of root and PC2 root to shoot ratio, leaf area ratio, specific leaf area and stem length increase significantly and freshly, root length and number of root in PC1 and stem length and root to shoot ratio in PC2 were the most important traits. Analysis of variance for nonlinear regression that indicated height, diameter and leaf number showed in wastewater stress significant differences of one percent. The application of wastewater had a positive influence on the growth of Celtis caucasica trees.
