Thirty-seven warm-season bermudagrass (Cynodon spp.) accessions, two cool-season grasses (Lolium perenne and Festuca arundinacea), 'Transvala' digitgrass (Digitaria decumbens), and Sorghum bicolor were evaluated to determine host suitability and susceptibility to the sting nematode, B. longicaudatus, in a 140-day microcell bioassay. All seven of the evaluated commercial cultivars of Cynodon wer...

Empirical and theoretical evidence suggests that facilitation between plants, when it occurs, is more likely during periods of abiotic stress, while competition predominates under more moderate conditions. Therefore, one might expect the relative importance of competition vs. facilitation to vary seasonally in ecosystems characterized by pronounced dry (abiotically stressful) and wet (benign) s...

AIM The effects of N-P-K fertilizers in the form of urea, single super phosphate and muriate of potash on development of free-living stages of Haemonchus contortus were studied. MATERIALS AND METHODS Five parasite free experimental plots of 1 m×1 m area, each of paddy leaves (15-day-old) and an equal number of Cynodon dactylon grass were infested with about 10×104 eggs/ml phosphate buffer sal...

Cynodon is a genus of plants with forage potential that has attracted the interest of breeders. These species have high morphological variability in a large number of varieties and cytotypes, hampering identification. This study aimed to determine the karyotype asymmetry index among accessions of Cynodon to discriminate between them. Karyotype symmetry was based on three estimates, which were c...
