The influence of the vesicular-arbuscular mycorrhizal fungus Glomus intraradices (Gi) and superphosphate (P) on penetration, development, and reproduction of Meloidogyne incognita (Mi) was studied on the Mi-susceptible cotton cultivar Stoneville 213 in an environmental chamber at 28 C. Plants were inoculated with Mi eggs at planting or after 28 days and destructively sampled 7, 14, 21, and 28 d...

Fungus-growing ants in the tribe Attini represent a classic example of a mutualism. These ants obligately depend on fungus as their major food source, while the fungus receives both vegetative substrate (nourishment) from the ants and protection from pathogens. Here, we try to identify both benefits and costs of the association by using cultivar switch experiments. We assessed the benefits to e...

Manual cultivar identification diagram is a new strategy for plant cultivar identification based on DNA markers, providing information to efficiently separate cultivars. We tested 25 pairs of apple EST-SSR primers for amplification of PCR products from loquat cultivars. These EST-SSR primers provided clear amplification products from the loquat cultivars, with a relatively high transferability ...

Flowering time of the short-day plant Chrysanthemum morifolium is largely dependent upon daylength, but it is also distinctly influenced by other environmental factors. Flowering is delayed by summer heat. Here, the underlying basis for this phenomenon was investigated. Heat-induced flowering retardation occurred similarly in C. morifolium and C. seticuspe, a wild-type diploid chrysanthemum. In...

A yeast glucan elicitor causes the accumulation o f the pterocarpan phytoalexins medicarpin and maackiain in chickpea ( Cicer arietinum) cell suspension cultures established from seeds. A cell culture line from a chickpea cultivar resistant against its main fungal pathogen Ascochyta rabiei accumulates large amounts (944 nmol/g fr. wt.) whereas a cell culture line from a susceptible cultivar acc...

An untargeted GC-MS approach was performed to study the stability of volatile fraction and taste five different single-cultivar strawberry purees during pasteurization (95 °C/1 min) accelerated storage (14 d at 35 °C). The PLS-DA results showed that varied markedly among cultivars in fresh purees; with Honeoye Sengana exhibiting most distinctive profiles more than 8 discriminative markers. Howe...

Broccoli (Brassica oleracea L.) is a widely consumed cool-season crop that is well-known for its health benefits and high nutritional content. With a growing consumer interest in local and organic foods, it would be helpful to determine if farmers can improve the nutrient and antioxidant content of broccoli through cultivar selection and to gain insight into environmental effects on nutritional...

1 Hudeiba Research Station (ARC), P. O. Box 31, Eddamer, Sudan 2 National Centre for Research, Environment and Natural Resources Research Institute (ENRRI) P. O. Box 6096 Khartoum, Sudan *Corresponding Author’s E-mail: [email protected] The performance of two chickpea in response to three Rhizobium strains was evaluated. The main objective of the work was to study the effect of inoculation ...

Two phenolic compound parameters (total phenolic and flavonoid contents) and 5 antioxidant parameters (DPPH [2, 2-diphenyl-1-picrylhydrazyl] radical scavenging activity, HRSC (hydroxyl radical scavenging capacity), FRAP (ferric ion reducing antioxidant power), CUPRAC (cupric ion reducing antioxidant capacity), and MCA (metal chelating activity) were measured in bulbs and bolts of 43 garlic cult...
