BACKGROUND AND AIMS Trifolium repens (white clover) is a valuable component of pastures due to its ability to fix nitrogen. Productivity of T. repens is sometimes threatened by insect pests, and it has been suggested that phenylpropanoid-derived isoflavonoids such as formononetin can protect white clover from insect damage. The aim of this study was to isolate and functionally characterize an i...
ELF-INCOMPATIBILITY is the inability of a plant producing functional male and female gametes to set seed upon self-pollination. The best known genetic system effecting incompatibility in plants is that in which a single series of oppositional alleles governs pollen-tube growth, with pollen behavior under autonomous, or gametophytic, genetic control (EAST and MANCELSDORF 1926). Self-incompatibil...
Background and objectives: The application of growth-facilitator materials to improve germination, early establishment, and plants growth can increase the success of rangeland improvement, planting, and pasture construction projects. In addition, growth facilitators can improve the quantity and quality of vegetation cover and production in dry-farming lands by increasing the success of cultivat...
