Translocation of nitrogen in the xylem of field-grown cherry and poplar trees during remobilization.
Studies of small trees growing in pots have established that individual amino acids or amides are translocated in the xylem sap of a range of tree species following bud burst, as a consequence of nitrogen (N) remobilization from storage. This paper reports the first study of N translocation in the xylem of large, deciduous, field-grown trees during N remobilization in the spring. We applied 15N...

The immediate and prolonged effects of p-dimethylaminoazobenzene on the increase in weight, net amount of pentoseand deoxypentosenucleic acids and acid deoxyribonuclease activity in the rat liver after partial hepatectomy have been studied. A slight depression of the rate of dry weight increase was noted after feeding DAB to the rats for 60 days. Discontinuation of the carcinogen brought about ...
Tropical stem-succulent trees store large quantities of water in their trunks yet remain leafless during the early and mid dry season. In contrast to most other tropical trees, bud break of vegetative buds is not induced in fully hydrated stem succulents between the winter solstice and the spring equinox by leaf abscission, abnormal rain showers or irrigation. Vegetative buds of leafless trees ...
this research was conducted to examine the effect of a concurrent training on rest level of leptin of plasma and some hormonal factors in non-athlete subjects. the research population included non-athlete men who didn’t participate in any organized sport activities. 30 men were chosen voluntarily among the above-mentioned population and were divided into 2 groups: experimental (15 subjects) an...
A total of 130 Arian broiler chicks were used in this study in order to assess the effects of tryptophan, melatonin and dark regimes on the performance and blood parameters of chickens exposed to heat stress. The chicks were allocated to the experimental units in an unbalanced completely randomized design. The treatments were control group, 40 mg of melatonin per kg of diet from 30-40 days of a...
