“…Wahid et al (2007) determined that hydrogen peroxide increases germination and germination index in wheat grown on saline soils (Wahid et al, 2007). The use of hydrogen peroxide solution stimulates seed germination and vigor in wheat, due to increased peroxidase activity (Liheng et al, 2009). Hydrogen peroxide enhances seed quality in safflower, as it oxidizes germination inhibitors in the seed coat, thus improving germination (Dolatabadian et al, 2008).…”

The objective of this study was to examine the effect of primers on seed quality parameters using different starting values of germination. For this purpose, ten soybean lines selected at the Institute of Field and Vegetable Crops, Novi Sad were evaluated. The starting values of germination ranged between 48% and 89%. Seeds were surface sterilized with 3% sodium hypochlorite and immersed in different primers: 1% potassium nitrate, 1% potassium chloride and 1% hydrogen peroxide. Untreated seeds were used as the control. The obtained results revealed that the effects of priming depended on soybean line and treatment, whereas the efficiency of this pre-sowing treatment was not affected by the starting value of seed germination. Some lines responded favorably to immersion, while in others priming had an inhibitory effect, causing a significant decrease in germination. There was an increase in germination up to 12% or a decrease up to 11%, depending on line and treatment. Lines that were positively affected by this method also exhibited increased values for other germination parameters: mean germination time (MGT) and time to 50% germination (T50). Lower values of MGT and T50 were observed in lines which showed a negative response to priming and a decrease in germination, but also a more rapid radicle protrusion, as compared to the control.In conclusion, there is no universal applicability of one single primer as it might cause a negative response in some lines and thus reduce seed quality.

“…Treating the seed with these primers gave significantly better results in seed vigour (11.2 and 11.3) with relation to other two primers and control variant (8.6). Taking wheat as an example, it was proven that the use of hydrogen peroxide solution stimulates germination and seed vigour since it improves activity of peroxidase enzyme (Liheng et al 2009). Mohammadi & Amiri (2010) proved positive effect of KNO 3 on germination and vigour of the rapeseed seed.…”

The objective of this paper was to examine the effect of seed lot, sowing date, and priming on germination and vigour of soybean seed. Three different seed lots of an old soybean variety (Lot 1, Lot 2, Lot 3) created at the Institute of Field and Vegetable Crops in Novi Sad were used. There were three sowing dates: 10 April, 20 May and 20 June. KNO 3 (1%), H 2 O 2 (0.1%), GA 3 (0.075%) and distilled water were used as primers. The results showed that soaking the seed prior to sowing, so called priming, positively affected seed germination and vigour in all three lots and with all three sowing dates. The best effect was accomplished with Lot 1 and sowing on the third date. With regards to primers, the best effect was achieved with the application of KNO 3 and H 2 O 2 solutions. Research has shown that even soaking the seed in distilled water, which is a simple, cheap, and ecological method of priming, in most cases leads to improvement of germination and vigour of soybean seed.

“…Leaf traits like emergence, elongation and expansion are thought to be important characteristics accounted for improved photosynthesis. Higher photosynthetic rates are absolutely associated with an enhanced leaf expansion rate (He et al, 2009). Henson (1985) reported leaf size as a basis for selection of rice cultivars keeping in mind the end goal to conserve water.…”

AbstractWater deficit conditions are a bearing on plant growth and development leading to diminished crop productivity. However, improving the crop productivity is need of the time to sustain the food security under ever increasing world population. Drought episodes are increasing with varying intensity and duration. Drought stress imposes alterations in crucial plant growth and developmental processes, including germination, plant height, stem diameter, number of leaves, leaf size and area, dry matter production and partitioning, flower and fruit production, and maturity. Nonetheless, plants show some morphological changes to cope with drought stress by lowering water loss, enhanced water uptake and maintenance of tissue water status. Some plants complete their life cycle early before the onset of drought to escape water deficit conditions. Identification of effects of drought stress on morphological attributes and morphological changes in response to drought can be promising for selection and breeding of drought resistant genotypes.
