Parental conditions, such as temperature, soil moisture, nutrient availability, light and competition during plant growth and seed maturation, influence seed quality and germinability. Elevated CO2 concentration can be also treated as a parental condition and should be considered when evaluating crop productivity under future climate conditions. Available information on the effect of parental C...

An experiment was conducted to evaluate and compare the seed extraction methods on physiological quality of eggplant seed in Seed Technology Laboratory of Bangabandhu Sheikh Mujibur Rahman Agricultural University during 2012-2013 growing season. Full ripen standard size fruits (60 DAA) of eggplant var. BARI begun-5 (round shape) and BARI begun-8 (long shape) were harvested and kept in ambient c...

The success of germination, growth and final yield of every crop depends to a large extent on the quality of the seeds used to grow the crop. Seed quality is defined as the viability and vigor attribute of a seed that enables the emergence and establishment of normal seedlings under a wide range of environments. We attempt to dissect the mechanisms involved in the acquisition of seed quality, t...

The effect of different pre-sowing seed treatments and sowing dates on germination and rootstock quality of ber was assessed to standardize a combination which could yield optimum germination and quality rootstock. Of the fourteen pre-sowing treatments, highest seed germination and best seedling growth was obtained in T10 x D2 (seed soaking in water for 48 hours followed by 6 days storage in mo...

In field peas, ascochyta blight is one of the most common fungal diseases caused by Didymella pinodes. Despite the high diversity of pea cultivars, only little resistance has been developed until to date, still leading to significant losses in grain yield. Rhizobia as plant growth promoting endosymbionts are the main partners for establishment of symbiosis with pea plants. The key role of Rhizo...

Although rice is a key crop species, few studies have addressed both rice seed physiological and nutritional quality, especially at the tissue level. In this study, an exhaustive "multi-omics" dataset on the mature rice seed was obtained by combining transcriptomics, label-free shotgun proteomics and metabolomics from embryo and endosperm, independently. These high-throughput analyses provide a...

Background and aims Short periods of extreme temperature may affect wheat (Triticum aestivum) seed weight, but also quality. Temporal sensitivity to extreme temperature during seed development and maturation was investigated. Methods Plants of 'Tybalt' grown at ambient temperature were moved to growth cabinets at 29/20°C or 34/20°C (2010), or 15/10°C or 34/20°C (2011), for successive 7-d peri...

in order to evaluation the effects of different soil fertility systems on chickpea seed quality, field experiments were carried out in sanandaj agriculture research station of iran in 2007 and 2008 growing seasons. experimental units were arranged in split-split plots based on randomized complete blocks with three replications. green manure levels considered main plots, base fertilizer compound...

The effect of constant temperature on the germination rate and percentage of two cotton seed lots was determined using a thermogradient plate. A gradient of 10 oC to 40 oC was established across the plate so that temperatures changed 2 oC for each 5 cm increment in length, resulting in sixteen different temperature treatments. The optimal temperature zone for germination was 28 oC to 30 oC. As ...
