abstract growth retardants are new chemical organic compounds that increase period of flowering, leave chlorophyll, lateral shoot number, flower number and decrease vegetative growth. they also increase dry, cold and heat tolerance. paclobutrazol and cycocel are examples of these compounds. this study was conducted to evaluate the effect of paclobutrazol and cycocel on some quantitative and qua...

It has often been stated or implied that grazing is an important factor in the land degradation process, a suggestion supported by various research projects, and this study investigated the effect of livestock grazing on stem height, crowncover, production, basal diameter, stem biomass, litter, leaf-stem index (leaf to stem weight) , root diameter and weight and seed production per individual o...

The present study has assessed the effect of Cola in increasing flower longevity of flower and delaying aging of cut Alstroemeria ‘Balance’. Distilled water was used as control. Traits of flower diameter, solution absorption ,anthocyanins, total soluble solids and chlorophyll were measured at 3 times and vase life was measured daily. Based on the results, flower diameter, anthocyanins and chlor...

Suitable selection of cultivars, is one of the important determinant factors that affects on quantity and quality of bulb flowers at the climate of Iran. In order to, introducing superior cultivars of gladiolus for cultivation in temperate regions of Iran, the experiment was carried out in a complete randomized block design (CRBD) in three replications with five cultivars of gladiolus including...

Investigation was done to find out the effect of different polyamines viz., spermine and spermidine (5, 10, 20 mg/l) biostimulants 2 % Novel (banana pseudostem sap) 2% cow urine as foliar spray on growth parameters rose var. Top Secret.
 Plant height, number branches leaves were found be significantly higher with biostimulants. Maximum plant height in plants treated mg/l while maximum sper...

A pot experiment was carried out to determine the effect of foliage spraying of silicon (Si) on growth and ornamental characteristics of calendula grown under salt stress and greenhouse conditions. A factorial experiment based on completely randomized design was conducted with 3 levels of Si (0, 50 and 100 mg/l) and 3 levels of NaCl (0, 100 and 200 mM) with 4 replications. At flowering stage, S...
