چکیده

Seed security is central to crop production for smallholder farmers in developing countries, but it remains understudied relation long-term seed sector development. Here, we compare systems two districts of Central Ethiopia characterized by subsistence-oriented teff cultivation and commercially oriented wheat relate this the country’s pluralistic system development strategy (PSSDS). Our analysis based on quantitative qualitative information from a household survey focus group discussions with farmers, as well document review key informant interviews actors that make up study sites. Farmers both used range sources primarily obtained their seeds informal sources. Evidence insecurity was found districts, apparent discrepancies between what say they prefer those actually use, limited availability improved varieties especially certified these, challenges quality some sources, differentiated access preferred according sex, age wealth. We find interventions prioritized PSSDS address most dysfunctions identified, implementation lags, particularly system, which largely neglected government programs. The intermediate shows promise, while improvements have been made formal vested political, organizational, economic interests within institutions represent major obstacles must be overcome achieve truly integrative inclusive

Imprinting and seed development.

Imprinted genes are expressed predominantly from one allele in a parent-of-origin–specific manner. The endosperm, a seed tissue that mediates the transfer of nutrients from the maternal parent to the embryo, is an important site of imprinting in flowering plants. Imprinted genes have been identified in maize and Arabidopsis thaliana, but crosses in a variety of species suggest that the effect o...

Update on Legume Seed Development Using Genomics to Study Legume Seed Development

Seeds are essential for flowering plant reproduction because they protect, nourish, and contain the developing embryo that represents the next sporophytic generation. In addition, seeds contain energy resources that sustain the young sporophyte during germination before photosynthesis begins. In legumes, food reserves stored in embryonic cotyledons make seeds important as a food source for both...

Wheat and barley seed system in Syria: farmers, varietal perceptions, seed sources and seed management

A total of 206 wheat and 200 barley farmers were interviewed in northeastern Syria to understand farmer perceptions and practice relating to modern varieties, seed sources and seed quality. Wheat farmers had better awareness and grew modern varieties (87%), applied fertilizers (99.5%), herbicides (93%), seed treatment (90%) or insecticides (41%). In contrast barley growers had low awareness (36...
