Chemicals on germination

The study was aimed to investigate the effects of different microwave heating times (1, 2, and 3 min at output microwave of 800 W) in comparison with the traditional heating (3 min, 110oC) on some physico-chemical properties and sensory evaluation. The consumer survey for the final product use was also conducted to determine whether there is a significant difference in general liking of the product with gender. The results indicated that the product with the shorter microwave heating time contained higher protein and reducing sugar compared to traditional heating.

Invasion by alien perennial weed Mikania micrantha has created a serious problems in Southeast Asia. This climbing vine possesses very fast growth rate and could multiply from seed and vegetative parts. It climbs on other plants, create a dense cover and block sunlight thereby damage or kill the other plant. It compete for water, soil nutrient and release allele-chemicals inhibiting growth of plants. The weed creates economic loss to plantation, horticultural crops, displaces and kills native vegetation. It is designated as one of the worst invasive plants of the world. M.

The study species possess seed coat imposed dormancies that require pre-sowing seed treatments. Based on the results, the best treatments to release dormancy in both S. galpinii and V. robusta are sulphuric acid and mechanical scarification, as these yielded the highest, fastest and most uniform germination of seeds.

Groundnut kernels are highly sensitive to seed deterioration mainly due to their chemical composition and moisture content. During the seed deterioration membrane degradation precedes loss of seed vigour and germination. Membrane degradation is measured by the electrical conductivity of seed leachate.

Induced mutations not only alter the plant genome but also affect the cellular component which leads to changes in seed germination to maturity traits. The aim of the present study was to investigate the somatic effect of chemical mutagen Ethyl Methane Sulphonate (EMS) on seed germination, shoot length, root length, plant photosynthetic pigments and nine yield attributing traits of two white seeded sesame varieties.

Sweet corn (Zea mays L. spp. saccharata) also known as sugar corn is a hybridized variety of maize (Zea mays L.) specifically bred to increase the sugar content. The information on storage of sweet corn seeds to preserve viability and vigour from harvest to next planting season is of prime importance in any seed production programme. Certain seed treatments and storage containers are known to influence the storability of seeds in several crops.

This study was performed by exposing the seeds of groundnut (Arachis hypogaea L.) to ethyl methane sulphonate [EMS] sodium azide [SA] to study their effects on various morphological traits when compared with control. The seeds of groundnut were pre-soaked in distilled water for 6 hours for ems and 24 hrs for SA. The SA, EMS solution was prepared in distilled water. Each concentration of SA, EMS was prepared in 100ml of distilled water for 300 groundnut seeds. These soaked seeds treated with different concentration of SA, EMS such as 0.2%, 0.4%, 0.6%, 0.8, 0.10% and 0.12 %.

In the present study, SDS-Polyacrylamide gel electrophoresis was used to separate protein sub units of albumin and globulin under reducing conditions to study the induction or disappearance during inhibition of germination. The molecular masses of the albumin and globulin protein subunits were estimated in relation to the motilities of the standard molecular mass proteins (Bio-Rad). However the SDS PAGE resolution of seed albumin in Pusa vishal and K851 showed 9-13 band corresponding to 110-5.

Ethrel 5000 ppm recorded highest germination (86 %) after 30 days of experiment followed by 200 ppm gibberellic acid (84.33 %) and 1000 ppm ethrel (80.67 %). Least germination (19.0 %) was observed in control. H2SO4 36N resulted in maximum in vitro strawberry seed germination and it was statistically at par with H2SO4 30N. Minimum number of days (2.00) to 50 per cent germination was also recorded with 36 N H2SO4. Maximum number of days (7.00) was taken by the lowest concentration of H2SO4.
