Moringa oleifera Lam. (synonym: Moringa pterygosperma Gaertn.) (M. oleifera) known in 82 countries by 210 different names is well known by the name of the miracle tree. It is one of the extensively cultivated and highly valued members of Moringaceae, a monogeneric family, comprising of thirteen perennial angiosperm shrubs and trees[1-3]. Moringa tree is endemic to the Himalayan foothills of Pak...
abstract previous researches have shown success of growth hormones usage on flower production increase, pod and prevention of abscission of them in some of the pulses. two tests were done, in order to find out the effects of growth hormones to on flower production increase, pod and chick pea yield composites in farmer conditions (2010-11) and green house conditions as factorial on the proje...
This work evaluated the effect of seed size and morphology on the development and biomass of durum wheat seedlings. Three different seed-grading sizes selected by sieving were used in glasshouse experiments, and a set of three developmental and 23 biomass-related indices were measured on eight genotypes, at two moisture levels. The influence of seed size on seedling development was studied at h...
The comparative effects of different concentrations of saline soil and saline irrigation water were investigated on growth of canola (cv. Ganyou-5). Plants were subjected to control (non-saline), 0.2% (EC 2.5 dS.m-1), 0.4% (EC 4.5 dS.m-1) and 0.6% (EC 6.5 dS.m-1) of sea salt concentrations in soil as well as saline irrigation water. Vegetative growth parameters recorded were plant height, numbe...
BACKGROUND Jatropha curcas L. (Jatropha) is a potential biodiesel crop that can be cultivated on marginal land because of its strong tolerance to drought and low soil nutrient content. However, seed yield remains low. To enhance the commercial viability and green index of Jatropha biofuel, a systemic and coordinated approach must be adopted to improve seed oil and biomass productivity. Here, we...
The seed maturation program only occurs during late embryogenesis, and repression of the program is pivotal for seedling development. However, the mechanism through which this repression is achieved in vegetative tissues is poorly understood. Here we report a microRNA (miRNA)-mediated repression mechanism operating in leaves. To understand the repression of the embryonic program in seedlings, w...
In order to investigate the effects of seed priming by salicylic acid (SA) and Paclobutrazol (Pa) on parsley, as a medicinal plant, under drought stress, a factorial experiment, based on completely randomized design with four replications, was performed at the Research Greenhouse and Laboratory of Department of Horticulture, University of Mohaghegh Ardabili. Experimental treatments included fiv...
In order to investigate the appropriate combination of chemical and bio-fertilizers and their effectiveness on corn seed yield while defoliating the upper leaves of the ear, a randomized complete block design experiment with four replications. Fertilizer treatments were applied at four levels including 100% urea, 75% urea + 100% Nitroxin, 50% urea + 100% Nitroxin, 25% urea + 100% Nitroxin. In h...
Due to the availability of limited water resources in the country, it is necessary to use unconventional water. On the other hand, application of minerals such as Zeolite (Zo) is necessary to simulate plant growth and reduce the harmful effects of wastewater. The present study was conducted to investigate the effect of irrigation by wastewater with Zo on cotton (Gossypium herbaceum) based on a ...
Forage brassica (Brassica napus cv. Greenland) is bred for vegetative growth and biomass production, while its seed yield remains to be improved for seed producers without affecting forage yield and quality. Cytokinins affect seed yield by influencing flower, silique and seed number, and seed size. To identify specific cytokinin gene family members as targets for breeding, as well as genes asso...
