There is little information about the effects of ethephon ripening hormone on the yield of sweet sorghum in Thailand. Therefore, this study aimed to evaluate the impact of ethephon hormone applied at different growth stages of three cultivars of sweet sorghum on its growth and yield. The experiment was conducted from December 2016 to May 2017 at a research plot of the Faculty of Agricultural Te...
This study was conducted to determine the effect of growth hormone on some growth and immunity parameters at three stages of rainbow trout eyed egg, alvin and fry. The experiment was carried out in 4 treatments with concentrations of 0, 0.1, 0.5 and 1 mg/l of somatotropin hormone. For permeability, different experimental groups were treated with sodium hypochlorite (0.005 %) for 15 seconds befo...
this study was conducted to determine the yield response factor (ky) of sugar beet to deficit irrigation at different growth stages. a field experiment was conducted in sharekord agricultural research station over two growing crop seasons (1996 -1997) using a randomized complete block design with three replications. plots were assigned to five levels of deficit irrigation treatments: e0 (full i...
this study was conducted to determine the chemical composition and degradability characteristics of a pasture plant salsola tomentosa by nylon bags method .the sampling was performed from the northern region of plain's gonabad city in three growth stages (vegetative, flowering and seeding). the samples dried in air, were milled and their chemical composition were determined. to determine the de...
Effect of growth stages on total phenolics content and antioxidant activity of Fumaria vaillantii L.
Background and objectives: Plant extracts and their constituents are known to exert biological effects, especially antioxidant activity. Fumaria vaillantii (Fumariaceae) has several therapeutic effects in traditional medicine. Antioxidants are able to protect the human body from oxidative damage connected to the reaction of free radicals. Synthetic antioxidants have to...
Background and objectives: Variation of active substances in medicinal plants during growth has been studied and the optimum harvest time has been determined for many medicinal plants. Ducrosi anethifolia is one the species belonging to Apiaceae family that has been used to improve the odor of food and drink. It is used also to treat catarrh, headache and backache in f...
Soil salinity is an increasing environmental stress on crops in most areas of Iran since farmers use underground saline water for irrigation. In order to investigate the effects of salt stress on germination and seedling growth of safflower (Carthamus tinctorius L.), an experiment was conducted at two stages (germination seedling growth), using four levels of NaCl salinity (0, 5, 10, 15 ds/m), ...

In order to investigate the effect of pest and water stresses on different growing stages of cowpea (Vigna sinensis) and pest occurrence, an experiment was conducted in Khazaneh Research station of Isfahan University of Technology. The experiment was carried out in a factorial complete randomized block design, in two different farms, with and without insecticide application. The treatments incl...
Regulated deficit irrigation (RDI) is commonly used during different phenological stages of fruit growth and development in almond trees to reduce the amount of irrigation water applied without or with only very small reductions in yield. Therefore, to study the effects of deficit and cutoff irrigation during different phenological stages of fruit growth and development in almond cv. “Mamaei” p...
