Z2 containing 2,4-D 0.5 mg/l+NAA 2.5 mg/l+KIN 0.5 mg/l induced highest 6.36% callus in BRRI dhan-29. Medium containing 4.0% sucrose gave the highest 7.5% callus formation as well as highest green plants regeneration. Pretreatment of cold shock is beneficial for callus induction and regeneration of haploid plants. Chromosomes counting was made from root tips and observed 69.0% haploids (n=12) in BRRI dhan-29. In the second part effect of three basal media MS, N6 and LS supplemented with four growth regulator treatments on the response of induction of callus from three different sources of explants like mature seed scutella, roots and immature embryos of four rice genotypes was studied. The highest callus formation 88.8% was recorded in Taipei-309 from mature seed scutella. Calli were subcultured with tryptophan in MS+2,4-D(1.0 & 1.5 mg/l)+NAA 0.5 mg/l for somatic embryogenesis. Regeneration response of embryogenic calli was tested on RM1, RM2 and RM3 and highest 79.5% calli formed shoots in BRRI dhan-29 from immature embryos in RM3. ····· 10361100110

This book deals only with the better known or better studied aspects of plant growth regulation by hormones. The book is written for third and fourth year undergraduates and beginning graduate students who have had basic botany and some introduction to biochemistry and molecular biology. It is designed to complement texts in plant physiology. Like most other text books, it originated because there was no single text that covered the burgeoning field of hormonal and environmental regulation of plant growth that was reasonably up to date. Since then, research in plant growth and development, spurred on by the application of molecular and genetic techniques, has revolutionized our thinking in plant biology. Many other individuals played important roles in completion of this book. Finally, but probably the most important, credit goes to my wife for providing support and encouragement at some of the bleakest moments during the writing of this text. ····· 10361100003

The information regarding morphological and palynological characterization along with pollen fertility estimation of about 50 species of 37 genera belonging to 7 families are studied in detail. Morphological characters help in understanding the adaptation and differentiation in particular environment while the pollen morphology and its fertility estimation is closely related to its function and many of the pollen features helped the species to adapt the life on particular geography and disperse its pollen in successful manner to fertilize the egg for the production of a new plant. The data derived from the research can contribute to the taxonomy of these families and may provide new dimensions towards further research in the discipline of morpho-palynological systematics. ····· 1036199968

The soil moisture stress as a whole reduced the yield and yield contributing characters of wheat. Correlation analysis of grain yield with yield attributing characters indicated a high positive correlation coefficient with total dry matter, crop growth rate, leaf number/plant, harvest index, spikelet number/spike and 1000 kernel weight. Growth analysis showed that both crown root initiation and heading stages were the critical and care is needed at these stages for better crop yield. However, heading stage was more critical. Stress study clearly showed that the varieties differed from one another in their tolerance to stress and among the varieties studied, Gaurab was comparatively least susceptible one while Aghrani was the highest highest susceptible. Phenotypic regression analysis also showed that Gaurab had unit regression slope with low stability value for grain yield/plant, fertile tiller number and 1000 kernel weight indicating its stability to varying soil moisture treatments. ····· 1036199766

Present studies on a crop plant Brassica juncea L. Czernj & Cosson exposed to Al elicited many visual symptoms, which were typical of mineral deficiency leading to loss of vigour. The ameliorative effect of Ca on Al toxicity was investigated on Brassica that involved an affordable and practical method to contain the toxicity through soil amendments with some salts of Ca, which is available locally and plentifully. It was found that a dose of 1200 µg g 1 of Ca as calcium carbonate was sufficient to protect the crop from rhizotoxicity induced at 500 µg g 1 of Al. A comparative pot-culture study of different salts of calcium was made to find out its most suitable anionic moiety. It was revealed that the salt of calcium carbonate worked the best, as it increased soil pH more than other two salts tested. Our study further revealed that Brassica plants irrigated with local tube-well water were free from Al-induced toxic effects even at much less of Ca-salt applied to the soil. ····· 1036199711
