Reproduction of reniform nematode Rotylenchulus reniformis on 139 soybean lines was evaluated in a greenhouse in the summer of 2001. Cultivars and lines (119 total) were new in the Arkansas and Mississippi Soybean Testing Programs, and an additional 20 were submitted by C. Overstreet, Louisiana State Extension Nematologist. A second test of 32 breeding lines and 2 cultivars from the Clemson Uni...

Salt stress is one of the most chalanging abiotic stresses affecting natural productivity and causing significant croplosses worldwide. A greenhouse experiment was conducted to evaluate the response of two alfalfa cultivars (Bamiand Hamedani) to 6 levels of salinity (0 as control, 25, 50, 75, 100, 125 mM NaCl) at the College of Agriculture,Shiraz University, Shiraz, Iran in 2008. Plant dry weig...

Two commercial cultivars of tomato, Alta and Peto 95, the accession line number LA716 of Lycopersicon pennellii and lines 94GH-006 and 94GH-033 (backcrosses between Peto 95 and LA716), with different leaf acyl sugar contents were screened for resistance to Bemisia argentifolii Bellows & Perring (corresponding to the Spanish B-biotype of Bemisia tabaci (Gennadius)), in greenhouse- and field-no-c...

the strawberry spider mite (ssm), tetranychus turkestani ugarov & nikolski, is an important pest of greenhouse cucumber in tropical and temperate regions of the world. the use of the host plant resistance is a basic method to reduce pesticide application in greenhouses. in this study, the biological responses of ssm to six greenhouse cucumber cultivars (puia, hedieh, milad ghadim, milad jad...

Abstract Wheat stem sawfly, [Cephus cinctus (Hymenoptera: Cephidae)], females display complex behaviors for host selection and oviposition. Susceptible hollow wheat (Triticum aestivum L.) cultivars release a greater amount of attractive compound, (Z)-3-hexenyl acetate receive number eggs compared to resistant solid cultivars. However, barley (Hordeum vulgare is becoming more common C. in Montan...

Four different rapeseed (Brassica napus L.) cultivars CZL, Benefit, Iwas and ZhongZhuang9, were used to analyse physiological responses higher doses of cadmium (Cd) their ability Cd accumulation. Plants exposed for 30 days dosages (0, 50, 100, 150 mg Cd/kg) in soil under greenhouse conditions. Cadmium was accumulated more roots than shoots all tested cultivars, with the highest ZhongZhuang9.
