to determine the effect of pot level and nutrient leaching on albinism disorder in strawberry (fragaria ananassa duch cv `camaroso`) cultivated in perlite substrate an experiment was conducted in 2006. yield was determined three times (january-february, march-april and may-june). the results indicated that plants located in an upper position showed more albinism (40.42%) which could be related ...

In this research, effect of drought stress on leaf characteristics was investigated in the experimental field of Miandoab Azad University, Iran using four facultative barley cultivars. Two separate experiments were conducted in pot and field conditions. In both experiments a factorial arrangement was used and the treatments were completely randomized in four replications. In each experiment ha...

Global climate change will modify plants in terms of growth and physiology. To better understand the consequences this effect, responses leaf water relations nitrogen (N) use efficiency barley tomato to elevated CO2 (e[CO2], 800 ppm) combined with progressive drought stress at two levels N supply (N1, 0.5 g pot?1 N2, 1.0 pot?1) were studied. The grown separate phytotrons ambient (a[CO2], 400 e[...

Growing Hippeastrum in an open field or a greenhouse requires precision irrigation and fertilizer to promote plant growth development. Therefore, this research aimed study the effect of level combined with fertilization rate on development Hippeastrum. Two experiments were carried out determine influence growth, flowering, bulb quality In first experiment, bulbs ‘Red Lion’ circumferences 25 cm ...

Oak regeneration in temperate forests often fails the presence of understorey grass. Competition by resource exploitation between plants has been extensively studied. By contrast, competition interference, especially chemical interference (allelopathy), much less thoroughly examined and its relative importance remains unclear. We investigated influence allelopathic interaction on plant performa...

Drought stress is one of the limiting factors for grain filling and yield in wheat. The determinants individual weight depend on current assimilation extent remobilization culm reserves to grains. A pot experiment was conducted with eight wheat cultivars at Pot House study contributions culm, including sheath under drought stress. enforced by restricting irrigation during grain-filling period. ...

Improved seeds are increasingly being sown in agricultural practice. Such treatments play different roles depending on the substances used. They most often protect and sprouts from abiotic biotic stresses, but not only. Coating technology is one of methods seed improvement, requiring selection appropriate components. The purpose pot experiment was to test efficacy two coatings (C D) a commercia...

abstract the association between neotyphodium spp. endophytes and cool-season grasses, particularly tall fescue (festuca arundinacea, schreb), represents a widespread type of mutualism in nature. numerous researches were performed about positive effect of symbiosis on plant resistance to different stresses but the role of symbiosis on nutrients uptake particularly potassium uptake and k-bearing...
