Studies on phosphate use efficiency of wheat in Egypt

Abstract

Genotypic differences in the efficiency of use of phosphorus and other nutrients in wheat was evaluated in a field study. The experiment was conducted during the 1991/92 and 1992/93 seasons on a virgin loamy sandy soil (pH 7.9) with low available phosphorus, in Ismailia, Suez Canal, Egypt. Because of arid climate, water was applied through sprinkler irrigation throughout the growing period (November to May). Shoot samples were taken at four developmental stages. Results show that there are substantial differences in phosphorus use efficiency of wheat. Biomass production, grain yield, straw yield, number of ears per m{sup 2}, and the number of grain per ear differed substantially at different phosphorus levels but there was no major difference in the 1000 grain weight. Wheat cultivars also showed significant differences in their P, K, Ca, and Mg contents. Eighteen local wheat cultivars (Triticum aestivum L.) were grown in the field to obtain information about root characteristics and vesicular-arbiscular mycorrhiza fungi infection that known to play a role in phosphate use efficiency of crops. Some root parameters such as root volume, root dry matter, root length and vesicular-arbiscular mycorrhiza infection rate were measured at three development stages. In addition, root diameter and root density  More>>

Some root parameters such as root volume, root dry matter, root length and vesicular-arbiscular mycorrhiza infection rate were measured at three development stages. In addition, root diameter and root density were also measured. Wheat cultivars efficient in phosphorus use have a high root density in the sub soil region and this is accompanied with a high vesicular-arbiscular mycorrhiza infection rate. Cultivars showed differences in root morphology and vesicular-arbiscular mycorrhiza infection rate. Some cultivars had a low root density and vesicular-arbiscular mycorrhiza infection rate and these cultivars exhibited a high phosphorus use efficiency. This was particularly true with cultivars 14, 16, and 18. This information may be useful to plant breeders in their attempts to breed wheat cultivars efficient in phosphate uptake and use. 41 refs, 2 figs, 4 tabs.}
