Abstract
The effects of Lead acetate [Pb(CH3COO)2] content of chlorophyll and proline were investigated in 15-to 75 days Fabaceae member plant of Dolichos biflorus (L.) in lead acetate treatment of Control to 10,25,50,75,100 and 200 mg/kg soil with various concentration of [Pb(CH3COO)2]. The control to pb treated 15 to 75 -days plants were taken and measured for total chlorophyll content of “aˮ and“ b”. The proline content was measured by using spectrophotometer under 520 nm. The total chlorophyll content was decreased with increased concentration of pb treatment, whereas proline content was measured on 15to 75 days plant of after lead acetate treatment. The bio-chemical content of total chlorophyll and proline was significantly affected with treatment of [Pb(CH3COO

A pot culture experiment, conducted Jatropha curcas. (L.) to germination and seedling growth the metal cadmium was added in the form of cadmium chloride. Different concentrations of cadmium (C, 10, 20, 40, 60,100 and 200 mg kg-1 soil) were prepared and used for germination studies. Plants were grown up to 30 days. The inner surface of pots was lined with a polythene paper. Each pot contained 5kg of air dried soil. The 10 seeds were sown in each pot. All pots were irrigated daily. In the studies from the results obtained that the increase in cadmium concentration affected all the growth parameters such as germination percentage, length of root and shoot, number of leaves, fresh weight of root, shoot and leaf, vigour index and tolerance index.

Abstract
This study was aimed to compare the effect of physical and chemical mutagens, namely gamma rays and EMS on seed germination, survival of seedlings and pollen sterility of sesame genotype TMV3. The seeds of sesame variety TMV3 were subjected to different doses of gamma rays such as 10, 20, 30, 40, 50, 60, 70, 80, 90, 100KR and various concentrations of EMS like 0.2, 0.4, 0.6, 0.8, 1.0, 1.2, 1.4, 1.6, 1.8 and 2.0mM. Seed germination test was carried out in laboratory to find out the LD50 values of Gamma rays and EMS and they were 50KR for gamma rays and 1.0mM for EMS. Based on the LD50 values, the following doses and concentrations were chosen to treat the seeds and conduct the field experiments. For Gamma rays, they were 30, 40, 50, 60 and 70KR and for EMS they were 0.6, 0.8, 1.0, 1.2 and 1.4mM and for Combined treatments they were 30KR+0.6mM, 40KR+0.8mM, 50KR+1.0mM, 60KR+1.2mM and 70KR+1.4mM. The effect of mutagens was measured for quantitative characters like seed germination, seedlings survival, seedlings height and pollen sterility and calculations were made. The results indicated that the seed germination, seedling survival and seedling height were decreased with increasing doses or concentrations of mutagens when compared to control. But in case of pollen sterility, it was increased with increasing concentrations of mutagens when compared to control. In combined treatments, plants showed high percentage of pollen sterility when compared to individual treatments and some plants showed complete sterile at 70KR + 1.4mM treatment.

Abstract
Endophytic microorganisms are to be found in almost every plant on earth. These organisms reside in the living tissues of the host plant and do so in a variety of relationships ranging from symbiotic to pathogenic. The aim of the present work was to investigate the fungal endophytes from the medicinal plant Argemone Mexicana.L and Aristolochia baetica.L. The isolate fungal endophytes and might be producing reasonably and pharmaceutically important bioactive (IAA, Enzymes) compounds from these plants. The determine of the antifungal activities of methanol, ethanol chloroform and aqueous extracts of Aristolochia baetica. Leaf against fungi by agar disc diffusion method. The antifungal assay was done against endophytic fungi (Aspergillus niger, Aspergillus flavus, Penicillium sp.). For all the cases it showed significant result.

Abstract
This paper deals with the systematic studies on antifungal and antibacterial activity from Mimosa pudica L. We are analyze the shade dried and powdered plant materials were extracted with methanol, chloroform, ethanol using a soxhlet apparatus and water extract was centrifuged at 5000 rpm were using supernatant. Gram negative bacteria strains of Escherichia coli, Klebsiella pneumoniae and Gram positive bacteria of Staphylococcus aureus, Streptococcus pyogensis, and Bacillus subtilis and the fungal strains of Aspergillus niger, Aspergillus flavus, Aspergillus fumigatus, Aspergillus awamori and Penicillium janthinellum were studied antimicrobial assay by using disc diffusion method. The different concentrations of the extract to understand the most effect microbial activity of microorganism

Abstract
Swietenia macrophylla King – a valuable tropical timber species produce seeds in small quantity with annual variations. Despite of approximately 126-210 flowers per inflorescence, only one to two fruits develop generally. The reasons are not known. We, therefore, had undertaken a detailed study on the structure and development of flowers and fruits and pollination mechanism for the first time. Results showed that mahogany is monoecious with unisexual flowers borne on the same inflorescence in the ratio of 2 male: 1 female. The period between floral initiation and fruit maturity was 8½ months. Flower drop, heavy immature fruit fall within a fortnight after fertilization and the insect, Hypsipyla robusta infestation during early stages of development are the main causes for low seed production in mahogany
