Physiological mechanisms of drought tolerance in sorghum, genetic basis and breeding methods: A review

African Journal of Agricultural Research

Afr. J. Agric. Res.

Sorghum is grown in semi-arid to arid regions of the world and serves as the staple food for about half a billion people in sub-Saharan Africa and Asia. The adaptation of grain sorghum to a wide range of environmental conditions has led to the evolution and existence of extensive genetic variation for drought tolerance. Consequently, sorghum is expected to play an increasingly important role in agriculture and meeting world food demand in the face... Read more

Atom-field interaction, hydrogen atom and nature of detuning

International Journal of Physical Sciences

Int. J. Phys. Sci.

The nature of detuning in transition probabilities in atom field interaction has been investigated in the light of hydrogen atom problem. It has been shown that the detuning bears a striking similarity with the principal quantum number n in hydrogen atom.   Key words: Induced resonant transition, detuning, hydrogen atom. Read more

Effects of rice straw burning products on guinea pig lungs

African Journal of Pharmacy and Pharmacology

Afr. J. Pharm. Pharmacol.

This study aims to investigate rice open field burning and their deleterious effects which has become an obvious problem in Egypt, which apparently affects the Egyptians´ lungs and increased hospital admission for pulmonary complaints. Therefore, this study was designed to investigate this phenomenon by using guinea pigs which were subjected to rice straws burning products (RSBP). The effects of RSBP on differential leukocytic count in lung... Read more

Effect of some phytohormones on growth characteristics of Chlorella sorokiniana IAM-C212 under photoautotrophic conditions

African Journal of Biotechnology

Afr. J. Biotechnol.

The effects of some phytohormones [indole acetic acid (IAA), indole butyric acid (IBA), gibelleric acid (GA3), and kinetin] on cell dry weight, cell number, cell size, protein and chlorophyll contents of Chlorella sorokiniana IAM-C212 were investigated under photoautotrophic conditions. Treatment with IAA (15 mg/l) and IBA (15 mg/l) resulted in significantly higher dry cell weight and cell number than the control (P < 0.05) but there were no... Read more
