  The experiment was conducted in the Tissue Culture Laboratory of the Department of Crop Botany, Bangladesh Agricultural University, Mymensingh for micropropagation of tomato plant to evaluate the effect of variety and Plant Growth Regulators (PGRs) in MS medium on callus proliferation from infected tomato plant. Three tomato varieties namely, Bahar, Binatomato-2 and Binatomato-3 were used as plant materials in the present study. Virus infected young internode segments of tomato plants were cultured on MS medium supplemented with different concentrations and combinations of Plant Growth Regulators (PGRs) for callus proliferation. The combination of 0.5 mg L-1 NAA + 2.0 mg L-1 BAP in MS medium was found the best for inducing healthy and light yellow callus after 15 days culture and callus turned into yellow at 30 Days After Inoculation (DAI) in all varieties. Calli were fully virus infected which was confirmed by ELISA test. These calli can be used for the production of virus free tomato plant by shoot derived meristem culture.

  The experiment was carried out at the field laboratory of the Department of Crop Botany, Bangladesh Agricultural University, Mymensingh during the period from March 2002 to June 2002 to evaluate the effect of biofertilizer (Bradyrhizobium) and plant growth regulators (GA3 and IAA) on growth of summer mungbean (Vigna radiata L.). The experiment was laid out by RCBD with three replications and two factors (variety and treatment). There were altogether 12 treatment combinations. Most of the growth parameters such as number of branches plant-1, number of leaves plant-1, number of effective nodules plant-1, number of non-effective nodules plant-1, root dry weight plant-1, nodule dry weight plant-1 was the height due to the application of biofertilizer (Bradyrhizobium). On the other hand, plant height, leave dry weight plant-1, shoot dry weight plant-1 and total dry weight plant-1 was the height due to the application of plant growth regulators (GA3 and IAA). However, biofertilizer (Bradyrhizobium) and plant growth regulators (GA3 and IAA) showed statistically identical performance on Crop Growth Rate (CGR) and Relative Growth Rate (RGR). In addition, among the mungbean varieties, Binamoog-5 performed better than that of Binamoog-2 and Binamoog-4.

  The study was carried out in the Field Laboratory of the Department of Crop Botany, Bangladesh Agricultural University, Mymensingh during the period from October 2000 to February 2001 to evaluate the influence of seed treatment with Indole Acetic Acid (IAA) by the concentration of 50 ppm, 100 ppm and 200 ppm on the growth, yield and yield contributing characters of two modern mungbean (Vigna radiata L.) varieties viz. Barimoog-4 and Barimoog-5. The two-factor experiment was laid out by Randomized Complete Block Design (RCBD) with 3 replications. In the experimental, seed treatment with 100 ppm IAA resulted the highest plant height, leaf area, leaf area index and number of seeds pod-1 (7.73). On the other hand, seed treatment with 200 ppm IAA resulted the highest Relative Growth Rate (RGR), Crop Growth Rate (CGR), Net Assimilation Rate (NAR), total dry matter, number of pods plant-1 (16.30), pod length (5.59 cm), fresh weight of pod plant-1 (13.00 g), dry weight of pod plant-1 (9.65 g), 1000-seed weight (40.10 g), seed yield plant-1 (4.99 g), harvest index (38.48). In addition, among the mungbean varieties, Binamoog-5 performed better than that of Binamoog-4.

  The experiment was conducted in the Tissue Culture Laboratory of the Department of Crop Botany, Bangladesh Agricultural University, Mymensingh, Bangladesh for micropropagation of tomato to evaluate the effect of variety and plant growth regulators in MS medium on shoot induction from virus infected calli of tomato plants. Three tomato varieties namely Bahar, Binatomato-2 and Binatomato-3 were used as plant materials in the present study. Callus derived shoots were induced on MS medium supplemented with different concentrations and combinations of plant growth regulators (PGRs). The combination of 0.2 mg L-1 IAA+4.0 mg L-1 BAP in MS medium was the best for inducing shoots which turned green to dark green after 15 days of culture. Callus derived shoots were fully virus infected which was confirmed by ELISA test. Meristem of plantlet can be used for the production of virus free tomato plant by meristem culture.
