The reproductive potential of Meloidogyne graminicola was compared with that of M. incognita on Trifolium species in greenhouse studies. Twenty-five Trifolium plant introductions, cultivars, or populations representing 23 species were evaluated for nematode reproduction and root galling 45 days after inoculation with 3,000 eggs of M. graminicola or M. incognita. Root galling and egg production ...

The objective of this study was to evaluate sweet potato clones for resistance to root-knot nematode, Meloidogyne incognita races 1 and 3. For each nematode physiological race, a greenhouse experiment was set up in a randomized block experimental design with three replications and six plants per plot. Fifty-eight sweet potato clones from the UFVJM germplasm bank were evaluated, plus five commer...

this study was conducted to determine the effects of arbuscular mycorrhizal fungi (glomus mosseae and glomus intraradices) symbiosis on mineral uptake of two pistachio cultivars (pistacia vera cv. qazvini and pistacia vera cv. badami-riz-zarand) grown in the greenhouse under different drought stress levels. drought stress (ds) reduced the mycorrhizal colonization in both cultivars as well as nu...

drought is still accounted as a serious agronomic problem and also one of the most important factors contributing to crop yield loss. the effect of sodium silicate (na2sio3, abbreviated as si) was investigated on the four major antioxidant enzyme activities and five other relevant components in two different grapevine cultivars (vitis vinifera l., cvs mish pestan and sahebi, as tolerant and sen...

the effect of arbuscular mycorrhizal fungi and plant growth promoting rhizobacteria, with the ability to produce acc deaminase enzyme, on water relationships and agronomic indices of sunflower (helianthus annuus l.) cultivars was investigated. the soil used was of an ec equal to 7.6 ds m-1. a greenhouse factorial experiment on the basis of a completely randomized block design with three levels ...

Endive (Cichorium endivia L.) is a leaf vegetable with high vitamin and nutritional values. Therefore, an increase of its cultivation in Poland and other European countries has been observed in recent years. The aim of this research was to study the effect of different growth media on the quality and photosynthetic efficiency of different endive cultivars. The experiment was conducted in contro...

Abstract “Autonomous fruit set” refers to self-pollination and set without pollen vectors such as vibration or insects. Autonomous under high-temperature stress is an important breeding goal climate change can reduce yields in Capsicum . We screened cultivars for autonomous ability a greenhouse environment investigated germination, viability, grains number, chlorophyll fluorescence (Fv/Fm), sty...

Two complementary approaches are being pursued at the University of Arkansas to develop FHB-resistant cultivars for the Mid-south. Following a severe outbreak of FHB in 1991, the breeding program initiated a crossing program between adapted soft wheat genotypes and 22 FHB lines from CIMMYT and Eastern Europe. These populations were advanced as bulks for 5 years. Then lines were developed using ...
