The action of species cytoplasm specific (scs) gene(s) can be observed when a durum (Triticum turgidum L.) nucleus is placed in the Aegilops longissimum S. & M. cytoplasm. This alloplasmic combination, (lo) durum, results in nonviable progeny. A scs gene derived from T. timopheevii Zhuk. (scs(ti)) produced compatibility with the (lo) cytoplasm. The resulting hemizygous (lo) scs(ti)- durum line ...

The low sulfur amino acid content of legume seeds restricts their nutritive value for animals. We have investigated the limitations to the accumulation of sulfur amino acids in the storage proteins of narrow leaf lupin (Lupinus angustifolius) seeds. Variation in sulfur supply to lupin plants affected the sulfur amino acid accumulation in the mature seed. However, when sulfur was in abundant sup...

Three hypotheses have been proposed to explain the functional relationship between seed mass and seedling performance: the reserve effect (larger seeds retain a larger proportion of reserves after germinating), the metabolic effect (seedlings from larger seeds have slower relative growth rates), and the seedling-size effect (larger seeds produce larger seedlings). We tested these hypotheses by ...

Comprising 34 groundnut genotypes an experiment was conducted in a randomized block design with three replication at the Research farm of Regional Agricultural Research Station, BARI, Hathazari, Chittagong during Rabi season (December 2009 to April 2010) for estimation of the multivariate analysis of divergence. The genotypes were grouped into five clusters. Cluster III contained the highest nu...

High adult mortality rate is expected to select for early maturation. However, physiological constraints or size-related reproductive benefits might select for delayed maturation, especially in small-bodied species. Additionally, the mating system and the relative intensity of mate competition can modify the timing of maturation. Here, we investigate the influence of mortality rate and mating s...

seed germination is the most sensitive growth stages of the plant to salinity stress. seeds of many species produce a jelly-like layer called mucilage upon exposure to water. the purpose of this study was to determine the role of mucilage in increasing salinity tolerance of lallemantia ibrica. seeds of this plantcontain mucilage that can be used to treat some diseases such as neurological, live...

ABSTRACT The use of desiccants allows to anticipate cowpea harvest at a time closer physiological maturity. saflufenacil and flumioxazin promote the drying falling leaves loss water from seeds. This study aimed evaluate effects doses applied crop on production quality seeds after storage for six months. Two experiments were carried out in split-plot design (5 × 2). In first experiment, main fac...

Background: Water stress may alter the seed chemical composition and cause changes in concentrations of non reducing soluble sugars seeds germination performance chickpea. We evaluated effect water during chickpea development on (i) accumulation non-reducing sugars, (ii) vigour germination. Methods: Three cultivars (Desi-K, Saina-K ICCV-K) were subjected to two regimes (water stress- withholdin...
