Eight cultivars Sorghum bicolor (L.) Moench were grown as callus cultures under induced, prolonged water stress (8 weeks), with polyethylene glycol in the medium. Concentrations of soluble carbohydrates and organic acids in callus were measured at the end of the growth period to determine differences in response to prolonged water stress. Sucrose, glucose, fructose, and malate were the predomin...

This paper aims at investigating the impacts of different planting methods on the yield and Cluster Charactersin different irrigation conditions on wheat (cultivar of Chamran) in Khuzestan for one year in Shavoor agricultural farm located in 70 km north of Ahvaz which lies in E longitude 48˚:28" and N latitude 31˚:50" as split plots in a randomized complete blocks design with three replications...

In undertaking cultivar trials, the variability of the response of the cultivars to the di¡erent environments in which they are grown introduces the possibility of release errors and non-release errors in the decisions made on the basis of the trial results. In this article a model is developed that accounts for the economic costs of those errors as well as the costs of operating the trials, an...

A nematicide, dibromochloropropane; the fungicides benomyl and maneb; an insecticide, oxydisulfoton; the herbicides trifluralin, linuron, and dinoseb; and fertilizers were applied to Heterodera glycines-infested soil. A resistant soybean cultivar alone produced the highest yield in one test, and its yield was not affected by application of pesticides or fertilizer. In two tests the cultivar tha...

One flavone-C-glycoside and two flavonol-O-glycosides were recognized and isolated as the main flavonoidal components in nine different carnation cultivars, and their chemical structures have been determined by spectroscopic methods, including UV detection, MS and NMR. The distribution of these three compounds in flowers, leaves, stems, young sprouts, and roots of each cultivar was evaluated by...

The number of transgenic cotton cultivars available for commercial production has increased greatly in recent years. Cotton producers now have multiple choices when choosing transgenic cotton cultivars. The choice of cultivar now dictates the insect and weed control programs that will or can be used. It is estimated that, in 2003, at least 77% of Arkansas’ cotton acreage was planted to a stacke...
