Yardlong bean pod used as vegetable in many countries. has agronomic character variability such length, immature and seed colour. The colour are green, whitish green red. Fagiola variety red pod, while "Aura Hijau" pod. aim of research was to evaluate characters F3 progenies. Artificial crossing made between "Fagiola" female parent male produce F1. F1 were self-pollinated F2. Then F2 obtain Pro...

Light is the ultimate energy source for all living organisms and is utilized primarily through photosynthesis by green plants. However there is a separate requirement of plants to be illuminated in which light acts not as an energy source but as an environmental trigger of developmental processes. This decisive role of light in controlling the growth of plants is described by the term "photomor...

cotton (gossypium hirsutum l. cv. varamin ) an important industrial crop of iran, is grown in 300,000 ha, with an average seed -cotton yield of 1750 kg.ha-1. the main obstacle in the way of increasing average cotton yield is imbalanced fertilizer use. along with urea and triple super phosphate, cotton growers also need k, mg, zn, fe, mn, cu, and b, so these elements’ critical levels should ...

'Candidatus Liberibacter asiaticus' (CaLas), a non-cultured member of the α-proteobacteria, is the causal agent of citrus Huanglongbing (HLB). Due to the difficulties of in vitro culture, antibodies against CaLas have not been widely used in studies of this pathogen. We have used an anti-OmpA polyclonal antibody based direct tissue blot immunoassay to localize CaLas in different citrus tissues ...

Nontarget injury from glyphosate drift is a concern among growers using non-glyphosate-resistant (non-GR) cultivars. The effects of glyphosate drift on nitrate assimilation and nitrogen fixation potential, nodule mass, and yield of non-GR soybean were assessed in a field trial at Stoneville, MS. A non-GR soybean cultivar 'Delta Pine 4748S' was treated with glyphosate at 12.5% of use rate of 0.8...

The hypothesis that net photosynthesis is diminished in many plant species because of a high rate of CO(2) evolution in the light has been tested further. High rates of CO(2) output in CO(2)-free air in comparison with dark respiration were found in Chlamydomonas reinhardi, wheat leaves, tomato leaves, and to a lesser extent in Chlorella pyrenoidosa by means of the (14)C-photorespiration assay....

this experiment was conducted in order to evaluate the effects of foliar application of ordinary and nano-particles of zinc oxide on the response of corn to salinity. treatments included two corn genotypes (seed mass and sc 704), three spray levels (zinc oxide, nano-sized zinc oxide, and a spray of water treatment) and three salinity levels (0, 75 and 150 mm nacl). shoot dry matter was decrease...

The extent to which vacuolar sugar transport activity affects molecular, cellular, and developmental processes in Arabidopsis (Arabidopsis thaliana) is unknown. Electrophysiological analysis revealed that overexpression of the tonoplast monosaccharide transporter TMT1 in a tmt1-2::tDNA mutant led to increased proton-coupled monosaccharide import into isolated mesophyll vacuoles in comparison wi...

The mineral contents of Centaura leave and seeds were determined by Inductively Coupled Plasma-Atomic Emission Spectroscopy (ICP-AES). Macro element concentrations (P, K, Ca, Mg and S) of samples were found at high levels. K was established at high level in both leave and seed samples of Centaurea. While K contents of leaves changes between 7254.10 mg/kg (Centaurea lycaonica) and 26396.36 m...
