Nitrate reductase, phosphoenolpyruvate carboxylase, and glutamine synthetase in annual ryegrass as affected by salinity and nitrogen
Autor: T. Kipnis, Moshe Sagi, Herman Lips, Amos Dovrat
Publikováno v: Journal of Plant Nutrition. 21:707-723
The concentration of organic acids, organic nitrogen (N), nitrate (NO3), and total cations increased in annual ryegrass [Lolium multiflorum Lam.) with salinity and N concentration in the growth medium. Increasing salinity and N in the growth medium i

Ionic balance, biomass production, and organic nitrogen as affected by salinity and nitrogen source in annual ryegrass
Autor: T. Kipnis, Herman Lips, Moshe Sagi, Amos Dovrat
Publikováno v: Journal of Plant Nutrition. 20:1291-1316
Studies on the effects of salinity and nitrogen (N) fertilization on ionic balance, biomass, and organic N production of annual ryegrass (Lolium multiflorum Lam.) were conducted. Plants grown in sand were irrigated with nutrient solution with an elec

Possible mode of action of Azospirillum brasilense strain Cd on the root morphology and nodule formation in burr medic (Medicago polymorpha)
Autor: Eli Yahalom, Yaacov Okon, Amos Dovrat
Publikováno v: Canadian Journal of Microbiology. 36:10-14
The mechanism(s) involved in the effect of Azospirillum brasilense strain Cd on root susceptibility to nodulation was studied in medic seedlings grown in pouches. The number of nodules above the position of the root-tip mark at the time of inoculatio

Alfalfa saponins and microbial transformations of nitrogen in peat
Autor: Dan Levanon, Yaacov Okon, Yigal Henis, Amos Dovrat
Publikováno v: Soil Biology and Biochemistry. 14:501-504
Alfalfa saponins, their sugar fraction or glucose, but not their sapogenin fraction, favored nitrogen immobilization and denitrification and inhibited proteolysis and ammonification in both peatinoculated and Pseudomonas sp.-inoculated media. Alfalfa

Alfalfa roots and nitrogen transformations in peat
Autor: Yaacov Okon, Dan Levanon, Yigal Henis, Amos Dovrat
Publikováno v: Soil Biology and Biochemistry. 11:343-347
Accumulation of NH+4 and NO−3 in peat was significantly reduced by living or decaying alfalfa roots. Alfalfa root extracts, alfalfa saponins, the carbohydrate fraction of alfalfa saponins and mono- and disaccharides inhibited NH+4 production and NO

Azospirillum effects on susceptibility to Rhizobium nodulation and on nitrogen fixation of several forage legumes
Autor: Eli Yahalom, Amos Dovrat, Yaacov Okon
Publikováno v: Canadian Journal of Microbiology. 33:510-514
Azospirillum brasilense Cd cell concentration of 105–107 colony-forming units (cfu)/mL applied 24 h before Rhizobium (106 cfu/mL), increased nodule formation in the non root hair zone, more than twofold, in pouch-grown Medicagopolymorpha and Macrop

Performance of the Swedish lucerne variety U 0615 from seed multiplied in Israel
Autor: Sven Bingefors, Amos Dovrat
Publikováno v: Euphytica. 14:315-325
Seed of the Swedish lucerne variety U 0615 harvested in a seed field in Israel for four consecutive seasons was tested in field trials in Sweden. Differences in seed yield between plants were demonstrated in Israel — less winter-dormant plants gave
