Boron nutrition and chilling tolerance of warm climate crop species.
BACKGROUND Field observations and glasshouse studies have suggested links between boron (B)-deficiency and leaf damage induced by low temperature in crop plants, but causal relationships between these two stresses at physiological, biochemical and molecular levels have yet to be explored. Limited evidence at the whole-plant level suggests that chilling temperature in the root zone restricts B u...
متن کاملImpacts of chilling temperatures on photosynthesis in warm-climate plants.
Photosynthesis in warm-climate plants is substantially reduced after chilling. Tropical and subtropical species offer the opportunity to study the effects of low temperature on photosynthetic processes undisguised by the myriad of protective responses observed in temperate species. In this article, we highlight the primary components of photosynthesis that are affected by a short chill, in both...

متن کاملThe Consequences of MinimumWage Laws: Some Theoretical Ideas Revisited
We develop an efficiency wages model, to study the effects of the imposition of a higher minimum wage on employment of heterogeneous workers, when employers use the wage and monitoring intensity to induce motivation. It is shown that when effort is adjusted to exogenous shocks then the wage and supervision, and employment and supervision can be either strategic complements or strategic substitu...
متن کاملTemperature-induced leakage from chilling-sensitive and chilling-resistant plants.
Leakage rates were determined from leaf cells loaded with rubidium and [(3)H]leucine. There was a differential response between leucine and rubidium leakage depending upon the species used. The rate of leucine leakage shows a small decline below 5 C for two altitudinal variants of Lycopersicon hirsutum Humb. and Bonpl., whereas Lycopersicon esculentum L. showed a marked increase below 5 C. Rubi...
