Mature-green tomato fruits were soaked in hot water for 10 minutes at 35, 40, 45 or 50°C and then stored at 13°C for 20 days. Untreated fruits were soaking with tap water (22°C). The study showed that exposing fruit to hot water influenced peroxidase (POD) and catalase (CAT) activities. Activity of the two enzymes increased with the increasing of soaking temperature, except for the 50°C treatme...

chickpea (cicer arietinum l.) is mainly cultivated in arid and semi-arid agricultural systems. drought stress is a major factor delimiting maximum yield. this research evaluated the effects of drought stress treatments on expression of cu/znsod as a gene involving in drought tolerance by real time pcr technique. to find the probable relationship between the molecular and physiological effects o...

Biennial bearing of apple trees can be overcome either by the use of a blossom chemical thinner or by early application of a postbloom thinner. Carbaryl (Sevin) is a postbloom fruit-thinning chemical with an effective thinning period of 4 to 5 weeks after bloom. Sevin was compared in 1992 and 1993 with NAA as an early petal-fall spray. Sevin treatments reduced fruit set to one fruit per cluster...

now a day winter cover crops planting has been attended to reduce herbicide application. an experiment was carried out at the research farm of agriculture faculty, bu- ali sina, university, in 2009. the experiment was a randomized complete block design with three replications. the trial included of five treatments consists of no cover crop, rye, winter oilseed rape, barley and triticale. the re...

To investigate the effects of irrigation intervals and humic acid application on some phophysiological and biochemical of thyme (Thymus vulgaris), the experimental in the form of factorial in the design complete randomized block in four replications at Miandoab University Research Field in 2019. Experimental treatments were at four levels of irrigation intervals (once every three days, once eve...
