Drought cause yield loss of soybean production is the major reason to yield losing of soybean. To improve the germination and growth of soybean seeds under drought stress; We studied the effect of the single walled carbon nanotubes (SwCNTs) material in seed germination and the physiological changes occurred under drought condition, performed SwCNTs treatments in soybean (Zhonghuang 35) seeds at...

The dormancy and seed germination of Tamarindus indica (L) was studied. This involved the usage of some dormancy-releasing methods and the influence of oven dry heat treatments on the seeds. The preliminary germination tests on fresh and air-dried seeds showed low percentage germinability (10-20%). The seeds are known to have high socio-economic value most especially in the savanna regions of t...

Leymus chinensis is a dominant grass in the Songnen grassland of Northern China. The lower germination caused by the presence of lemmas has proved to be an obstacle for the use of the seeds of this plant by humans. However, it is still unknown if the lemmas have other ecological roles such as resisting drought and saline conditions. Three experiments were designed to investigate the ecological ...

abstract germination and emergence of cold tolerant lentil genotypes sometimes experiences low temperatures and variable rainfalls in the fall planting. this study was conducted to evaluate the effects of drought stress on germination stage of lentil genotypes. experiment was carried out with 18 lentil genotypes under five levels of water potential (0 , -0.4 , -0.8 , -1.2 , -1.6 mpa) using peg ...

in order to investigate the germination characteristics and cardinal temperatures of biotype alhaji pseudalhagi, a laboratory experiment was conducted randomized completely design with four replications of 25 seeds. various constant temperatures 5, 8, 10, 15, 20, 25, 30, 35, 40, 45 and 50ºc were considered. the characteristics such as percentage of seed germination, rate of seed germination, th...

The dormancy status of S. faberi seed at abscission was assessed with reference to tiller and panicle development. Seed from a single genetic line were grown under field, greenhouse and controlled environment growth chamber conditions. At abscission, a small fraction (<10%) of S. faberi seed germinated under favorable conditions. Seed were dissected and germination of caryopses and embryos also...

The brownseed mutants (bs(1), bs(2), and bs(4)) of tomato all possess dark testae and deleteriously affect seed germination speed and/or final percentage. Poor germination performance of the bs(1) but not the bs(4) mutant, was due to greater impediment to radicle egress. Testa toughening (bs(1)) was prevented by drying in N(2). However, poor germination speed was hardly affected by drying. GA(4...

We investigated how pre-dispersal strategies may mitigate the effects of weevil infestation of acorns in a population of Quercus schottkyana, a dominant oak in Asian evergreen broad-leaved forests, and assess if weevil infestation contributes to low seedling recruitment. We counted the number of acorns produced, daily from the end of August to mid-late November for 9 years from 2006-2014. We al...
