Kiwifruit is a fast-growing deciduous woody vine that can be propagated in several ways. Nevertheless, seedlings have a strong and widespread system of roots than cuttings. The aim of this study was to find a simple and practical method for farmers to increase the germination percentage of kiwifruit seeds. This study was performed in a completely randomized design with five treatments of Cold S...
considering forage grass species, germination is one of the important stagesconcerning the growing stage that is often influenced by environmental stresses,particularly salinity and drought stresses. thus, this study aims to assess the effects ofsalinity and drought stresses on germination characteristics and seedling growth of desertwheatgrass, agropyron desertorum (fisch. ex link) schult. in ...
abstract- this experiment was carried out during the growing seasons of 2010 and 2011 at the agricultural research farm of bu-ali sina university, to study the effect of weed competition on subsequent germination and seed vigour of chickpea. 12 weed interference durations were evaluated in a randomized complete block design with three replications. experiments consisted of two sets of treatment...
Extended abstract Introduction: Today, various technologies have been developed to improve seed quality with the aim of increasing the percentage, speed and uniformity of germination and better seedling establishment under different environmental conditions. One of these technologies is seed pre-treatment or seed priming. In this regard, some studies confirmed that pre-treatment of seeds with ...
In this study, the effects of seaweed extract (Ascophyllum nodosum) on seed germination stimulation and growth indices in chickpea were studied. A factorial experiment was performed on the basis of a completely randomized design with 3 replications. Treatments consisted of seaweed extract at four levels (0, 1.5, 2.5 and 3.5%) and drought stress at four levels (0, -0.3, -0.6 and -0.9 MP). Drough...
in order to study the interaction of temperature and salinity on seed germination and seedling growth of cucumis melo a factorial experiment was conducted based on crd with four replications. the factors included four temperature levels (25, 30, 35 and 40 °c) and five salinity levels (0, -0.2, -0.4, -0.6 and -0.8 mpa). germination rate and percentage, shoot length, root length, seedling vigor i...
In order to study the effects of hormone and hydroprimng on seed germination, growth and antioxidant enzymes activity of borage seedling, an experiment was carried out based on completely randomized design with three replications at the University of Mohaghegh Ardabili in 2015. The Experimental treatments were seed priming with gibberellin (50, 100, 150 ppm for 12, 24, 48 hours) and salicylic a...
The chemical composition of fulvic acid (FA) with a molecular weight below 500 (FA-500) was analyzed, and its activity on promoting the seed germination of wheat was studied in this paper. The FA-500 was obtained by membrane separation technology and qualitatively and quantitatively analyzed by using gas chromatography-mass spectrometry combined with the retention index. Forty-seven constituent...
Cadmium (Cd) is one of the most important heavy metals and its pollution causes toxic effects on plants and human beinges well. Glycine betaine (GB) is an osmoprotectant that its external application leads to decrease stress strains as well as heavy metal accumulation hazards. This experiment was conducted to study the effect of seed priming with GB on Cd reduction of damages in the black seed...
