We investigated seed dormancy and germination in Ficus lundellii Standl. (Moraceae), a native species of Mexico's Los Tuxtlas tropical rain forest. In an 8-h photoperiod at an alternating diurnal (16/8 h) temperature of 20/30 degrees C, germination was essentially complete (96%) within 28 days, whereas in darkness, all seeds remained dormant. Neither potassium nitrate (0.05-0.2%) applied contin...

Bacillus cereus T spores were prepared on fortified nutrient agar, and the spore coat and outer membrane were extracted by 0.5% sodium dodecyl sulfate-100 mM dithiothreitol in 0.1 M sodium chloride (SDS-DTT) at pH 10.5 (coat-defective spores). Coat-defective spores in L-alanine plus adenosine germinated slowly and to a lesser extent than spores not treated with SDS-DTT, as determined by decreas...

Bacillus subtilis spores prepared in rich medium germinated faster with nutrient germinants than poor-medium spores as populations in liquid and multiple individual spores on a microscope slide. Poor-medium spores had longer average lag times between mixing of spores with nutrient germinants and initiation of Ca-dipicolinic acid (CaDPA) release. Rich-medium spores made at 37°C germinated slight...

Six selected cultivars of rice namely BPT-5204, MTU-7029, CSR-30, Narendra Usar Dhan-3, Rajendra Bhagwati and Pusa Basmati-1 were screened for salinity tolerance on the basis of in vitro seed germination and seedling growth under different salt stress (02.5%) created by a salt mixture of NaCl, CaCl2, and Na2SO4 in 7:2:1 ratio. At 2% salt stress, germination was only observed in cultivars CSR-30...

Dormancy breaking and germination requirements were investigated in seeds of Ferula ovina and Ferula gummosa. Seeds of rather species were collected from north and eastern-north rangelands of Iran. Seeds of each of the species were subjected to different treatments including various levels of GA3, chilling and combination of GA3 and chilling (GA-chilling). In contrast to treated seeds, non-trea...

in order to study of hydropriming and halopriming on germination and early growth stage of wheat (triticum aestivum l.) an experiment was carried out in laboratory of the department of agronomy and plant breeding, shahrood university of technology. seed treatments consisted of t1: control (untreated seeds), t2: soaking in distilled water for 18 h (hydropriming). t3: soaking in -1.2 mpa solution...

to study the effect of some varying treatments including such environmental factors as temperature, moisture, and light as well as plant growth regulators on breaking dormancy of datura stramonium l. seeds, several experiments were conducted. seeds of datura stramonium l. possess full dormancy immediately following harvest. storing the seeds for 3 months (15 dec. 2005 to 15 march 2006) at room ...

This study focused on improving and diversifying the food and nutrition status of soy milk prepared by germinating the soyabeans prior to soy milk preparation and evaluating its quality and potential for acceptance. The pH, moisture, fat, protein, ash and total solid content of raw material soyabean were 6.76, 12,17.67,39.6, 5.3, 88 %. Non-Germinated and Germinated Soy milk (from shorttime Soya...

Dietary quality is an important limiting factor for proper nutrition in many resource poor settings, with a major concern, micronutrient bioavailability. High content of phytate present in soybean (Glycine max. L) chelates divalent essential mineral ions and reduces its bioavailability and thus dictates the nutritional role of this wonder crop. In this study, the changes in phytate, phytase act...

The present study evaluated the effects of glyphosate on Pisum sativum germination as well as its effect on the physiology and biochemistry of germinated seedlings. Different physico-chemical biomarkers, viz., chlorophyll, root and shoot length, total protein and soluble sugar, along with sodium and potassium concentration, were investigated in germinated seedlings at different glyphosate conce...
