Rose (Rosa hybrida L.) is one of the mostly cultivated cut flowers in Iran and around the world. The study was carried out to increase the vase life and quality of cut rose ‘Grand Prix` and ‘Avallanche` by using various floral preservative solutions. Floral preservative solutions were AgNO3, 8-HQS, nano silver and distilled water. Treatments were compared with tap water as control. The experime...
The relevance of deionized water as a control treatment in vase life experiments and the effects of major tap water components on cut flower water balance were investigated. Chrysanthemum (Dendranthema x grandiflorum Tzvelev cv. Cassa) was used in all experiments. Deionized water gave a sharp decrease in fresh weight of the cut flowers after 1–3 days. This decrease was absent in tap water. Afte...
The experiment was carried out to investigate the effect of different concentrations of salicylic acid (SA), malic acid ( MA), citric acid (CA) and sucrose (Suc) on keeping quality and vase life of Chrysanthemum cut flowers. In this study three levels of malic acid (0, 100 and 150 mg l ) and salicylic acid (0, 1.5 and 3 mM) and two levels of sucrose (0 and 3% w/v) and of citric acid (0 and 150 ...
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...

The application of gibberellic acid (GA(3)) to the non-rosette long-day plant Lemna gibba G3 at concentrations from 0.1 to 100 mg/l did not induce flowering on short days and inhibited flowering on long days at concentrations of 1 mg/l and higher. On both short and long days GA(3) concentrations above 1 mg/l caused a decrease in frond size and fresh and dry weight, but an increase in the rate o...
To investigate ethylene's role in petal senescence, a comparative analysis of age-related changes in total protein, protease activity, and the expression of nine cysteine protease genes in the corollas of ethylene-sensitive Petuniaxhybrida cv. Mitchell Diploid (MD) and ethylene-insensitive (35S:etr1-1; line 44568) transgenic petunias was conducted. The later stages of corolla senescence in MD f...
to study the effect of plant density and planting pattern on iranian ox-tongue, an experiment carried out with two factors: planting pattern (square and rectangular pattern) and plant density (2, 4, 6, 8 plant m-2) in a factorial test performed based on rcbd in 3 replications during 2009-2010 in latmahalleh eshkevarat village in guilan province, iran. characteristics that measured included: dry...
in order to investigate the effects of hinokitiol (0.1, 1, 5 and 10 micromolar), humic acid (100, 500. 1000 and 10000 ppm), sucrose (2.5, 5, 7.5, and 10 percent), and silver thiosulphate (0.25, 0.5, 1 and 2 mm) treatments on longevity and some quality characteristics of cut yelloween lily flowers, an experiment was conducted in the form of a completely randomized design of two replications (tim...
introduction: production and growth of plants in many parts of the world due to degradation and water scarcity have been limited and particularly, in recent decades, agriculture is faced with stress. in the most parts of iran, especially in the khorasan razavi province, drought is a fact and water is very important. due to melon cultivation in this province, and the conditions of quality and qu...
