Seed detoriation is a mjor constraint for right production of different crops and seeds starts with physiological maturity crop up to storage. The process seed deterioration may be related various changes, such as continuous fall in germinability, an increase mean germination time, aberrant seedling frequency, lower tolerance unfavourable climatic conditions. Numerous physical chemical factors,...

Mature seeds of many crop species contain substantial amounts soluble carbohydrates, including raffinose family oligosaccharides (RFOs) and cyclitol galactosides (Gal-C). These substances are hydrolysed by α-D-galactosidase (EC 3.2.1.22) during the early stages germination, providing metabolic energy for germination process. A decrease or inhibition activity can significantly reduce rate. This ...

The role of relative humidity (RH) while processing and storing seeds of Brassica spp. and Eruca sativa was investigated by creating different levels of relative humidity, namely, 75%, 50%, 32%, and 11% using different saturated salt solutions and 1% RH using concentrated sulphuric acid. The variability in seed storage behaviour of different species of Brassica was also evaluated. The samples w...

The breeding of wheat with greater early vigour has potential to increase water- and nutrient-use efficiency, as well as to improve weed competitiveness to raise crop yields profitably. Given that wheat is inherently conservative in its early growth, a sustained breeding effort was initiated to increase genetically seedling leaf area in developing novel high vigour germplasm. A recurrent select...

Morpho-physiological and biochemical changes in developing cucumber (Cucumis sativus L) seeds were monitored under both open field (E1) protected environments (E2) during 2019 at ICAR-IARI, New Delhi. Fruits developed from hand pollinated flowers, Pusa Barkha Uday varieties harvested five-day intervals. The environment influenced days to maturity development of fruit and/or seed. Irrespective v...

Proteomics approaches have been a useful tool for determining the biological roles and functions of individual proteins and identifying the molecular mechanisms that govern seed germination, vigour and viability in response to ageing. In this work the dry seed proteome of four Arabidopsis thaliana genotypes, that carry introgression fragments at the position of seed longevity quantitative trait...

Nitrogen (N) remobilization from reserves to sinks is essential for seedling establishment and seed production. Cytosolic glutamine synthetase (GS1) is up-regulated during both seed germination and seed filling in plants. However, the specific roles of the individual GS1 isogenes with respect to N remobilization, early seedling vigour, and final seed productivity are not known. In this study, i...

Silver nanoparticle (AgNPs) is one of the widely used nanoparticles because their antimicrobial properties. In this present study, effect green synthesized silver and bulk form (AgNO3) at different concentrations (250, 500, 750 1000 ppm) on seed quality parameters groundnut were studied. using Azadirachta indica leaves characterized by Dynamic light scattering, UV- Vis FTIR spectrum. Size, zeta...

The field experiment was conducted at Seed Technology Research Center, Department of Plant breeding and Genetics, JNKVV-Jabalpur Kharif-2021. Growth analytical attributes studies indicated superior performance seed treatment with nano-ZnO @500mg L-1 for LAI @60 DAS (days after sowing), @70 DAS, @80 LAD, CGR, RGR BMD w.r.t. 24.26%, 21.39%, 28.50%, 12.09%, 21.42%, 20.17% 20.56% enhancement over c...
