Characterization of Mulberry Genetic Resources for Multiple Traits

Mulberry plants have wide range of variations in characters in view of its adaptability to cross pollination with no inter-specific reproduction barrier rendering it a heterozygous species. Every plant being different from the other in natural population, this great diversity makes it difficult to gather information and carry out studies on effect of different edaphic factors on the expression of genotypic characters for adjudging the variations. In lieu of this known diversity for posterity, the collection of mulberry genotypes from diverse genetic sources, their conservation, evaluation and consequent documentation is of prime importance. In the present study, 69 mulberry accessions were characterized for morphology, anatomy, and reproductive parameters. Evaluation for propagation, growth and yield characters were also carried out. Based on multiple trait analysis, 14 top performing accessions viz., MI-0879, MI-0882, MI-0908, MI-0931, MI-0907, MI-0940, MI-0881, MI-0941, MI0892, MI-0913, MI-0937, MI-0934, MI-0865, MI-0886 were identified. These accessions could serve as resources for further evaluation aimed at trait-specific crop improvement.

Hazardous Waste Management Approach for Heavy Metals in Soil by Phytoremediation

There have been a lot of practical applications of phytoremediation in the last ten years, involving organic, inorganic, heavy metal, and radionuclide remediation. India would find this to be an excellent alternative to conventional remediation methods as it is a sustainable and inexpensive process. The huge retention of industrial waste in soil resulted in soil pollution which is more hazardous due to the long-term persistence of contaminants. A major source of hazardous waste products in Bhopal city is the industrial region. Near residential areas, industries produce pollution that can be very harmful to human health. The objective of this research was to determine which heavy metal accumulators are capable of absorption and translocation of heavy metals. In the Govindpura sampling sites, Cr and Ni concentrations were higher, while Cd concentrations were lower. Phytoremediation was conducted by comparing the heavy metal accumulation of Datura inoxia, Calotropis procera, Ricinus commmunis, and Polygonum in vitro cultures.

Simulation of Total Dry Matter Production of Glycine Max L Merrill Under Weed Management Practices

An investigation on “Weed Management and Crop Growth Modeling in Soybean” was carry out on red sandy loam soil at UAS, Main Research Station, Hebbal, Bangalore during Rabi 2010 (September to December). The weed control practices included in the study were i) Pendimethalin 30 EC 1.0 kg a.i./ha – 3 days after sowing, ii) Imazethapyr 10 SL 100 g a.i./ha – 20 days after sowing, iii) Quizalofop-p-ethyl 5 EC 50 g a.i./ha – 20 days after sowing, iv) Chlorimuron ethyl 25 WP 6 g a.i./ha – 20 days after sowing, v) Hand weeding (20 & 40 DAS) and vi) un-weeded control. The experiment was designed as RCBD with four replications. Growth models – Richards, Logistic, Cubic polynomial and Quadratic polynomial simulated the course of dry matter production/plant by >97per cent under all weed management practices, indicating that weed competition did not alter the pattern of crop growth, but affected the total production substantially.

Chemical Analysis of Water Hyacinth Ash by XRD and SEM

The specific term for the Water hyacinth plant is Eichhorniacrassipes. The water plant that flows freely, rising at still or slower water sources. Water Hyacinth develops massive biomass and doubles its population in two weeks by fast-growing. These entail a loss of biodiversity, water pollution, water loss, agriculture, infrastructure damage and negatively effect on public safety, and water species. The objective of the study is to evaluate the chemical composition of water hyacinth ash by XRD and SEM .XRD is an obligatory method for analysing the characteristics and composition of materials. It is a non-destructive method to analyse all types of material substances like powder, crystals, and fluids. Nowadays X-ray diffraction Techniques are utilized in assorted fields like research, development, and production of materials. The particle size, shapes, surface roughness, and fracture are defined using aEDAX. When a sample is placed on the beam and multiple signals determine the interactions with the samples. Acetone is used to stop the hydration reactions. Then the specimen is dried and made to conduct. Finally, a micrograph was recorded using SEM.
