Malate dehydrogenase isolated from leaves of the cotton plant (Gossypium hirsutum L.) appears in the form of several isoenzymes. Four of the isoenzymes found in cotton leaf extracts appear to be charge isomers with a molecular weight of approximately 60,000. A fifth malate dehydrogenase isoenzyme found in leaf extracts has a molecular weight of approximately 500,000. Under appropriate condition...
To investigation the yield and yield component of cotton (Gossypium hirsutum L.) planted in conventional and ultra narrow row spacings, in competition with velvetleaf (Abutilon theophrasti Medic.) an experiment was conducted in a completely randomized block design with split plot arrangement of treatments, with three replications at Experimental Station of Gorgan University of Agricultural Scie...
introduction salinity is a major abiotic stress that affects approximately 7% of the world’s total land area. cotton (gossypium barbadense l.) is considered as one of the most important cash crops which is widely used for agricultural and industrial purposes. although, cotton is classified as one of the most salt-tolerant major crops but its growth and development are adversely affected by soil...
Two field experiments in 1993 and 1994 as well as a laboratory germination experiment were conducted on the Egyptian cotton cultivar Giza 75 (Gossypium barbadense) to determine the effect of six concentrations of kinetin (6-furfurylaminopurine) ranging from 0 to 10.0 mg l(-1) and three different methods of application: (A) seeds were soaked for 24 h before germination (laboratory experiment) or...
The ability of poultry litter to support plant growth by supplying essential plant nutrients in the absence of other sources of the nutrients has not been studied thoroughly. The objectives of this research were to (1) determine the ability of poultry litter, as the sole nutrient source, to provide macronutrients and support growth of cotton (Gossypium hirsutum L.) (2) evaluate the distribution...
Belonolaimus longicaudatus has been reported as damaging both potato (Solanum tuberosum) and cotton (Gossypium hirsutum). These crops are not normally grown in cropping systems together in areas where the soil is infested with B. longicaudatus. During the 1990s cotton was grown in a potato production region that was a suitable habitat for B. longicaudatus. It was not known how integrating the p...
Transgenic crops producing insecticidal proteins from the bacterium Bacillus thuringiensis (Bt) are extensively cultivated worldwide. To counter rapidly increasing pest resistance to crops that produce single Bt toxins, transgenic plant 'pyramids' producing two or more Bt toxins that kill the same pest have been widely adopted. However, cross-resistance and antagonism between Bt toxins limit th...
We announce here the genome sequence of Bacillus amyloliquefaciens strain UCMB5036, a plant growth-promoting bacterium isolated from a cotton plant. Its genome contains gene clusters involved in nonribosomal synthesis of secondary metabolites known for their antimicrobial activities. The availability of this genome will provide novel insights into plant-bacterium-associated activities.
Natural or synthetic elicitors can affect plant physiology by stimulating direct and indirect defence responses to herbivores. For example, increased production of plant secondary metabolites, a direct response, can negatively affect herbivore survival, development and fecundity. Indirect responses include increased emission of plant volatiles that influence herbivore and natural enemy behaviou...
to determine the best planting date and irrigation schedule in a cotton field (gossypium hirsutum var.varamin) in garmsar region an experiment was conducted in 2011. the experimental design was splitplot based on randomized complete block with three replications. three irrigation termination dates (2011sep 11th, 2011 sep 21st and 2011 oct 2nd) arranged in main plots as main factor and three pla...
