Growth and integrability in discrete systems

Abstract: We introduce a new discrete integrability criterion inspired from the recent findings of Ablowitz and collaborators. This criterion is based on the study of the growth of some characteristic of the solutions of a mapping, using Nevanlinna theory. Since the practical implementation of the latter does not always lead to a clear-cut answer, we complement the growth criterion by the singularity confinement property. This combination turns out to be particularly efficient. Its application allows us to recover the known forms of the discrete Painleve equations and to show that no new ones may exist within a given parametrization.

Auxin Analogues and Nitrogen Metabolism, Photosynthesis, and Yield of Chickpea

Abstract: The impact of three auxins indole-3-acetic acid (IAA), 4-chloroindole-3-acetic acid (4-Cl-IAA), and indole-3-butyric acid (IBA) on nitrogen metabolism were investigated in chickpea (Cicer arietinum L.). Plants were raised from seeds soaked in water (control), 10−8 M of IAA, IBA, or 4-Cl-IAA, for 12 hours and were assessed for different parameters at 60 days after sowing. Observations showed that auxins, irrespective of the analogue significantly increased the nodulation, leghemoglobin content, nodule nitrogen content and the enzymes of nitrogen assimilation. Of the three auxins, 4-Cl-IAA was the most effective in increasing these parameters. The increase in seed yield was 27% higher than the water soaked control. The response to auxins followed the trend 4-Cl-IAA > IAA > IBA > control. It may be concluded from the present investigation that auxins, irrespective of the type, significantly improved the nitrogen metabolism, photosynthesis and yield of the chickpea. Of three auxins used, 4-Cl-IAA gen...
