Prolonged drought of cowpea at the seedling stage can affect survival and productivity. This study sought to evaluate genotypes for their resistance seedling-stage stress. Fifteen were used in this study. The experiment was a factorial arranged Completely Randomized Design with three replications. Drought stress imposed 4 weeks after full expansion first trifoliate leaf. Soil Plant Analysis Dev...

This experiment was carried out in Islamic Azad university (Shoushtar Branch) for investigate effect of salt stress on seedling growth of soybean cultivars. The soybean cultivars (Hill, Klark and Williams) obtained from Iran seed and plant institute, Karaj, Iran. The experimental design was 2 factorial, arranged in completely randomized design with 4 replication. First factor was soybean cultiv...

Artificial excision of the distal part of acorns in order to promote germination is well researched in oak seedling cultivation studies. However, studies of combined effects of cotyledon excision and nursery fertilization on container seedlings are lacking, especially for seedling root growth and outplanting performance. This study aimed to explore the main effects of cotyledon excision on Quer...

Factors affecting survival and recruitment of 3531 individually mapped seedlings of Myristicaceae were examined over three years in a highly diverse neotropical rain forest, at spatial scales of 1-9 m and 25 ha. We found convincing evidence of a community compensatory trend (CCT) in seedling survival (i.e., more abundant species had higher seedling mortality at the 25-ha scale), which suggests ...

The use of resistant cultivars is the main strategy to control Fusarium wilt on tomato, caused by oxysporum f. sp. lycopersici . This study aimed quantify incidence and distribution this disease in region Nova Friburgo, RJ, as well type resistance tomato three FOL races. Samples healthy wilted plants from 40 properties were evaluated for presence vascular discouloration. Seventeen races using a...

Pearl millet is one of the most important cereals grown in drought-prone areas and is the staple grain for million of people in West Africa and India. Breeding for drought-prone environments is constrained by lack of suitable selection indices of drought stress resistance. The present study is conducted to determine the reliability of in vitro screening method for initiating drought breeding pr...

Seedling blight, caused by the fungus Fusarium oxysporum, significantly lowers rice production globally. Earlier reports have opined that endophytic bacteria strains could be possible biocontrol agents, but mechanistic actions involved are still unclear. Therefore, this study aimed to isolate with high inhibitory activity and elucidate its mechanisms for inducing resistance metabolomics. The re...

Seedling recruitment of Dalmatian toadflax, (Linaria genistifolia ssp. dalmatica (L.) Maire and Petitmengin (Scrophulariaceae)), was examined in a 2-year field study in Montana using overseeding and plant/insect exclusion methods, to determine whether it was more limited by seed availability or interspecific plant competition. Overseeding test plots with toadflax seed had no effect on seedling ...

Studia Forestalia Suecica 199, 25 pp. ISSN 0039-3150, ~ S B N 91-576-5152-3. Field experiments were carried out at four sites in Sweden to investigate the possibility of establishing downy birch (Betula pubescens Ehrh.) and silver birch (Betula pendula Roth) on abandon...

In plants encouraged by the proliferation of seed, seed to plant survival factor to maintain the role is very vital and important. In order to evaluate different size effect's on the quality seedling production during germination in wheat (Triticum aestivum L.), this experiment was conducted in 2011 at Laboratory Sciences, Islamic Azad University Shahr-e-Qods Branch by a completely randomized d...
