Pyrethrum is a perennial daisy grown commercially for the insecticide that is extracted from its flowers. In order to evaluate germination and seedling growth of pyrethrum under different temperature and drought stress treatments, an experiment was conducted in seed technology laboratory of Faculty of Agriculture of Islamic Azad University of Isfahan branch in 2018. During this experiment, poly...

Biocontrol agents isolated outside Africa have performed inconsistently under field conditions in Africa. The development of indigenous phytobeneficial microbial strains that suit local environments may help enhance competitiveness with in situ microorganisms and effectiveness at suppressing local pathogen strains. We isolated bacteria from the rhizosphere of maize growing in southwestern Niger...

The relationship between the apical hook and stem nutation in etiolated Alaska pea (Pisum sativum L. cv Alaska) seedlings was explored. The hook and maximum nutational displacement have the same plane of symmetry, and both are affected by light acting through phytochrome. However, the two processes do not appear to be obligatorily coupled. Light effects on nutation involve at least two componen...

Salinity and heavy metal stresses are great hindrances to germination the early developmentof plants. Nickel (Ni) is an indispensable micronutrient for plants at low while toxic in highconcentrations. Citrullus colocynth L. a medicinal cucurbit weed desert agriculturalareas. Germination development of seedlings determine future plant. Thecontemporary target study appraise influence single combi...

Jasmonic acid (JA) is a naturally occurring growth regulator found in higher plants. Several physiological roles have been described for this compound (or a related compound, methyl jasmonate) during plant development and in response to biotic and abiotic stress. To accurately determine JA levels in plant tissue, we have synthesized JA containing 13C for use as an internal standard with an isot...

Aquaporins play a major role in governing the movement of water between neighboring cells during seed germination and are major players in response to abiotic stress conditions that affect water availability. Seeds of pea (Pisum sativum L. cv. Arkel) were used for studying cell growth, expression and function of aquaporins during seed imbibition, radicle emergence and growth.Water channel funct...

To assessment effect of concentration and times of disinfection wheat seeds, infected by Aspergillus fungus a research was conducted based on Factorial experiment according randomized complete block design with four replications. The factors included four levels of sodium hypochlorite (2, 4, 6, and 8%) and four times of seed disinfection (2, 5, 7, and 10 minutes). Result of analysis of variance...
