Cím:	Effects of bio-fertilizers on changing of some photosynthetic parameters. / Veres Sz., Marozsán M., Szabó B., Makleit P., Lévai L.
Dátum:	2006
Megjegyzések:	As concerning dry matter production, a very important factor in agronomy, and the amount of photosynthetic pigment pool has an unquestionable role in it. The effects of three bio-fertlilizers and different reduced nitrogen concentration were examined on photosynthetic pigment concentration of corn seedlings' leaves under controlled conditions. The amounts of the main photosynthetic pigment group, i. e. total chlorophylls increased due to bio-fertilizers. The level of such increases depended on the starting time of treatments, it was more effective if the bio-fertilizers were used from the first day of experiments. Chrorophyll-a/chlorophyll-b ratios decreased under the effect of bio-fertilizers, primariliy, when they were applied form the first day of experiments also. The amount of another pigment group, protective carotenoids did not change significantly under the effects of bio-fertilizers. When bio-fertilizers were applied under limiting nitrogen concentration, our results showed, that that these bio-fertilizer compensate for nitrogen deficiency in both nitrogen concentrations used. According to the above, these bio-fertilizers can enhance the production by increasing the photosynthetic pigment concentration, and the efficiency of photosynthesis.
