The maize root system is crucial for plant establishment as well as water and nutrient uptake. There is substantial genetic and phenotypic variation for root architecture, which gives opportunity for selection. Root traits, however, have not been used as selection criterion mainly due to the difficulty in measuring them, as well as their quantitative mode of inheritance. Seedling root traits of...

to evaluate the effects of accelerated aging and cold stress on seed germination and seedling growth indices in five oilseed rape cultivars (hyola330, hyola401, hyola420, syn3 and pr401/15e), an experiment was carried out in a completely randomized design of three replications. results indicated that the cultivars were significantly different in germination percentage, seed vigour, germination ...

Loblolly and slash pine seed were inoculated at sowing with 1 of 12 different strains of plant growth-promoting rhizobacteria (PGPR) in the greenhouse. Time to germination and seedling densities were determined at 21 days, and seedling biomass was measured at 12 wk after sowing. All bacterial strains significantly increased the speed of seedling emergence over nontreated pine seed. By 12 wk, ho...

The results of present investigation revealed that among the different potting media treatments, M1: Vermiculite + Garden soil Sand was found to be most beneficial for improving took days germination, germination percentage, height seedling, number leaves seedling-1, stem diameter, primary roots length (cm), secondary roots, fresh and dry shoots weight, seed vigor index – I II leaf area (cm). I...

Objective: To evaluate the effect of chemical stimuli on germination and seedling growth of Caper (Capparis Spinosa) under drought stress. Methods: Factorial experiment in a completely randomized design with four replicates per treatment were performed. First factor of priming include three levels of acetylsalicylic acid (300, 200 and 100 mg/L), gibberellic acid levels (500, 250 and 12...

The effect of salt and drought stress at the water potentials of-2, -4,-6and -8 bars induced by NaCl and PEG 6000 (Polyethylene glycol 6000) each, on germination and early seedling growth, were investigated for two varieties (PU-19 and Type-9). Electrical conductivity (EC) value of the NaCl solutions were 4.5, 8.8, 12.7 and 16.3 dS m(-1). Germination percentage, root and shoot length, and seedl...

Climate change poses a threat to sorghum production systems by shifting the onset of the rainy season to a later date, increasing the risk of crop failure during crop establishment. The effects of drought on sorghum during seedling establishment have not been determined. Coating seeds with a water absorbing substance offers a way to buffer the seed against insufficient moisture in the surroundi...

The glyoxylate cycle is regarded as essential for postgerminative growth and seedling establishment in oilseed plants. We have identified two allelic Arabidopsis mutants, icl-1 and icl-2, which lack the glyoxylate cycle because of the absence of the key enzyme isocitrate lyase. These mutants demonstrate that the glyoxylate cycle is not essential for germination. Furthermore, photosynthesis can ...

Prosopis juliflora (Swartz) DC is one of the most economically and/or ecologically important legumes in arid and semi-arid regions of the world. Prosopis was introduced into Sudan in early 20 century, and succeeded in controlling the expansion of desert in northern Sudan. Recently, however, this species distributes widely and rapidly in eastern Sudan, and induces many problems in human subsiste...
