In order to improve the quality of cut rose ‘Dolce Vita’, an investigation was performed with 20 treatments, 3 replications, and 2 plants in each replicate in a greenhouse with the open soilless culture system. The treatments included control (distilled water), putrescine (Put) at the rates of 1, 2 or 3 mM, spermidine (Spd) at the rates of 0.5, 1 or 1.5 mM, spermine (Spm) at the rates of 1, 2 o...

The objective of this study was to investigate the effect of pruning in different developmental stages on growth, development, seed yield and active substances of medicinal pumpkin (these active substances are uses for remedy the Benign Prostatic Hyperplasia (BPH)). The experiment was performed in a RCB design. Five pruning treatments in different developmental stages (no pruning, after 3-5 nod...

 Increasing quality and vase life of cut flowers play vital role in flower production industry. . Lisianthus (Eustoma grandiflora cv. Echo) has short vase life and it has been revealed that ethylene directly affect the initiation and process of senescence of petals. In this study, the effects of Silver and silicon nanoparticles with four concentrations of 0, 10, 20 and 40 mg L-1 with 4% sucrose...

background & aim: german chamomile is one of the most important medicinal plants. so, assessment of genetic diversity and relationship among the traits are very essential in chamomile breeding programs. determination of the best indirect selection criteria for genetic improvement of essence percent and dry flower yield of german chamomile (matricaria chamomilla l.) populations was investiga...

Chrysanthemum cut flower is not sensitive to ethylene and its vase life depends on vascular blockage. In order to evaluating of effect of antibiotics and essential oils on the vase life and quality characteristics of chrysanthemum cut flower an experiment carried out based on a RCD with 10 treatments: Artemisia at 3 levels (10, 30 and 50 %), amoxicillin at 3 levels (100, 200 and 300 mg l-1), Ri...

abstract the irrigation water quality is not suitable for crop production in most regions of iran. it is estimated that almost six bcm/year of saline water enter to the rivers, in iran. the saline water can potentially use for growing of tolerant crops with a specific management on the agriculture practice. one of the management methods is the conjunction use of fresh and saline water. in this ...

This study was carried out to investigate the effect of hydropriming on seed germination and seedling growth of five different flower seed species (Antirrhinum, Dahlia, Impatiens, Salvia and Zinnia). Hydropriming (20oC, 24 h), surface dried or dried back afterwards, was found to increase germination percentage, seedling emergence and fresh and dry weight. In all species, the maximum advantage i...
