Pollen viability and its germination capability for fruit set in are almond and peach essential. To optimize the pollen culture medium of almond and peach and selection of best medium, the present study was carried out with 48 different culture media containing different compositions including diverse levels of boric acid (0 and 100mg/1), calcium nitrate (0,150and300mg/l،), magnesium sulphate (...

Pseudomonas fluorescens N.C.I.B. 8248 was adapted to grow on potassium d-glucose 6-O-sulphate as the sole carbon and sulphur source. Adapted bacteria grew optimally at 37 degrees C on 1.6% (w/v) sulphate ester and growth coincided with the disappearance of the ester from the culture medium at a rate of 2.4mg/h per ml. Three sulphated compounds were detected in the culture fluid at the terminati...

The purpose of this research is to investigate the effect potassium fertilization source and dose on productivity quality parameters strawberry. trial was conducted in 2016-2017 at experimental greenhouse Hassan II Institute Agronomy Veterinary Sciences Rabat. Strawberry plants cultivar “San Andreas” were planted November 6th 12 liter pots equipped with a gravity fertigation system. design spli...

1. Exchangeable potassium, sulphate space and intracellular fluid have been determined in eight normal males and in seven uraemic male patients on a regime of twice weekly 8 h dialysis. 2. Intracellular water was more closely correlated with exchangeable potassium than were body weight or lean body mass. 3. There was no correlation between exchangeable potassium and plasma or erythrocyte potass...

Urine formation by the Malpighian tubules of insects depends on an active transport of potassium (Ramsay, 1953, 1955; Berridge, 1967, 1968). However, potassium transport alone will not induce water transport unless it is accompanied by an anion. For example, if the chloride bathing the isolated tubules of Calliphora is replaced with a non-transportable anion such as sulphate, fluid transport ce...

The apparent molar volumes (?v) and viscosity B coefficients (Jones Dole)for Magnesium sulphate, Aluminium ammonium sulphate Potassium aluminium in aqueous Dimethylformamide (DMF) Dimethyl sulphoxide (DMSO) were evaluated from density (?) (?) at various temperatures as 308.15, 313.15, 318.15 323.15K with help of bicapillary pycnometer Ubbelohde viscometer instruments respectively. densitydata f...

Relati ve viscosities of some mineral salts viz; sodium sulphate, potassium sulphate, ammon ium sulpha te and magnes iu m sulphate, at di ffe rent concentrations have been determined in binary aqueous solutions of urea (mole-frac tions of urea, XII!""" = 0.0 10, 0.025 , 0. 040, 0.055 and 0.070) at 308. 15K and in XII!""" = 0.025 at di fferent temperatures. The data have been evaluated using l o...
