Seeds of alfalfa (Medicago sativa) and white clover (Trifolium repens) were primed in 3 priming solutions [2% NaCl, 2% KNO3 and 300 g/L polyethylene glycol (PEG)] for 2 days at 20°C and their subsequent germination compared with that of untreated seed. Four replications of 50 seeds for germination and 25 seeds for emergence were arranged in a 2-factor factorial completely randomised design. All...

The aim of the present work was to statistically design an autotrophic medium for maximum biomass production by Chlorella pyrenoidosa using response surface methodology. After evaluating one factor at a time approach, K2HPO4, KNO3, MgSO4.7H2O and NaHCO3 were preferred over the other components of the fog’s medium as most critical autotrophic medium components. The study showed that the maximum ...

the effects of priming treatment using five osmotic solutions (peg, manitol, kno3, kh2po4 and combination of two salts) in six osmotic potentials (-1 to -1.5 mpa) was studied on germination percentage, rate and uniformity of melon seeds. the best results were obtained with high concentrations of kno3 and lower concentrations of manitol. mean germination time of melon seeds in 19°c was preceeded...

The Raman spectrum of a KNO3 single crystal was measured at both room and liquid-nitrogen temperatures. Lattice-dynamical calculations, based on the rigid-ion approximation and empirical potentials, were performed. The possibility of a phase transition at 217 K was investigated by measuring the temperature dependence of the Raman spectrum. ©1992 The American Physical Society. Used by permission...

γ-Cyclodextrin-metal-organic frameworks (γ-CD-MOFs) are developed as a new promising and biocompatible material, which shows great potential for drug delivery system (DDS) applications. γ-CD-MOFs were successfully synthesized using microwave-assisted technique from different potassium sources (KOH, KCl KNO3). The encapsulation of olivetol (OLV) into these materials was investigated an innovativ...

Germination is considered a critical step in the development cycle of plant. But no information available regarding seed priming with Putrescine, Jasmonic acid, Kinetin, Potassium Nitrate (KNO3), Salicylic acid at time aged and non-aged seeds sorghum cultivars. However, to know effect aforesaid chemicals cultivars on germination rate, vigour alpha-amylase activity, research was conducted under ...

soil and water salinity in arid and semi-arid regions, is one of the most important stresses, can severely limit crop production. black cumin (nigella sativa l.) is annual important herbal plant in rununculaceae family that sense to salinity. this study was conducted to evaluate the effects of the priming on seed germination of black cumin under saline stress. the experiment was carried out as ...
