This study was carried out to evaluate the effects of different plant growth regulators on ornamental sunflower plant. The seedlings belonging Helianthus annuus L. cv. Sunsantion F1 were planted in plastic pots (2 L) containing peat:perlite (1:1, v/v) medium at four true leaf stage. Spray treatments aminoethoxyvinil glycine (AVG; 250 and 500 ppm), promalin (5 10 thidiazuron (TDZ; 5-10 µM), ethe...
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...
Dut to econemic and envaironmental limitiations of peat moss as a growth medium for ornamental plants, researchers seek an apporiate alternative in flower and plants industry. Zeolite, due to its high potential in water holding capcity and cation enchange capacity, has the ability to replace peat moss. To investigate the posibility of subtituting peat moss by zeolite as a proper medium for grow...
carbon dioxide (co2) concentration of the global atmosphere has increased during the last decades. increasing global atmospheric co2 concentrations are expected to influence on plants. coleus is an ornamental plants, that is due to its attractive foliage are considered. in order to evolution of high co2 concentration effects on rooting. morphological and anatomical traits in two coleus spices (...
Water deficit conditions, in addition to reduced water uptake, result in a reduction in nutrient uptake, and consequently, a substantial reduction in growth parameters, yield and quality. Substrate inoculation with arbuscular mycorrhizal fungi (AMF) as an environmentally friendly biofertilizer is an important strategy to improve the growth parameters and quality of products in such conditions. ...

In order to induce of autotetraploidy and to evaluate changes in morphological and phenology characters of Madagascar (Catharanthus roseus cv. Rosea) an experiment was implemented in a randomized complete blocks design with four concentrations of colchicine (0, 0.1, 0.2 and 0.4%) Spraying was carried out in six replicates in the two true leaf stages. The results of the analysis by using flow cy...
effect of manure and chemical fertilizer on physiological and phytochemical properties of coneflower
plant secondary materials play an important role in health and human nutrition. according to the importance of coneflower in the production of secondary materials and also the effect of nutrient on the amount of secondary materials, a pot experiment was conducted with a completely randomized design six treatments and three replications in sari university of agricultural sciences and natural res...
This study was conducted to evaluate the effects of paclobatrazol and cycocel on some quantitative and qualitative traits of zinnia. Seedlings were transplanted on Horticulture Department Farm , College of Agriculture, Isfahan University of Technology. The experiment was carried out in the framework of randomized complete block with 3 replications. Triats which were studied included plant heigh...
This research was performed to investigate the effect of different substrates and humic acid on quantitative and qualitative traits of cut Rose (Rosa hybrida cv. Angelina) in soilless culture. A factorial experiment was carried out in a randomized complete blocks design with three replications. The first factor was humic acid (HA) at 4 concentrations (0, 2, 4 and 6 gr/L) and the second factor w...
