The objective of the present work was to determine what impact extremely high nitrogen dosages would have on proline metabolism in order to use this amino acid as a bioindicator of N status of green bean plants (Phaseolus vulgaris L. cv. Strike). In this effort, we identified the most favourable pathway of proline synthesis under our experimental(More)
The aim of the present work was to examine the relationship between proline metabolism and NAD kinase activity in greenbeans submitted to cold-shock. For this, 15-day-old greenbean plants were subjected to a temperature of 4 degrees C (cold shock) for 180 min. Our results indicate that the plants showed foliar accumulation of proline, with the enzymes(More)
The objective of the present work was to determine the impact of nitrogen deficiency on proline metabolism in French Bean plants (Phaseolus vulgaris L. cv. Strike). The nitrogen was applied to the nutrient solution in the form of NH 4 NO 3 at 1.45 mM (N1), 2.90 mM (N2) and 5.80 mM (N3, optimal level). Our results indicate N deficiency is characterised by a(More)
In view of the essential role of phenolic compounds in the development of pathogen resistance in plants, and given the influence that fungicides exert over phenolic metabolism, the aim of the present study was to determine the effect of the application of different rates of fungicide on the metabolism of phenolic compounds in tobacco plants (Nicotiana(More)
The aim of the present work was to determine the in¯uence of different B dosages on foliar biomass and quality in tobacco plants (Nicotiana tabacum L var Tennesse 86). Tobacco plants were grown under controlled conditions and submitted to regular fertilisation with macro-and micro-nutrients. The B was applied to the nutrient solution in the form of H 3 BO 3(More)
To understand the phytotoxic effects that certain bezimidazole fungicides exert on plant growth, the aim of the present study was to determine the effect of the fungicide carbendazim, on foliar biomass, pigment content, and nutrient levels in tobacco plants (Nicotiana tabacum L. cv. Tennessee 86). The fungicide applied was carbendazim with a purity of 100%,(More)
