Germination Seeds From Powder Bio Attempts of Three Plants Khaya Senegalensis, Eucalyptus Camaldulensis, Azadirachta Indica for the Protection Against of Groundnut Weevils Caryedon Serratus Ol.

Abstract

The seeds treated to different products (Khaya senegalensis, Eucalyptus camaldulensis and Azadirachta indica) during bio-attempts of stocking present variations in germination percentage according to the biocide product for the test of Student-Newman-Keuls at the beginning of 5%. In considering one or different plant(s) and the types of vegetable powders, the non-treated indicators peanut ArNT (0g), (98.33 % ± 0.88) and chemical of reference P (0.5g), (90.66 % ±1, 00) are meaningfully different between them and are meaningfully different from powder formulations according to doses. Even if meaningful differences are detected, the results of the germination tests show rates higher than 75% which prove a good protection of seeds by the vegetable powders without affecting their germination power. However alternatives of bioattempts in presence of substance indicators inert in real environment could be envisaged in order to see the viability of treated seeds and this in a long-preservation period.Copy Right, IJAR, 2018,.

Introduction:-The viability of seeds is the measure of the seeds number in a group of seeds that are alive and can grow in plants that will develop in the appropriate conditions in the fields (Rao et al., 2006). To germinate, the seed should but submitted to favourable external conditions (water, light, temperature, oxygen) and internal (absence of inhibition and dormancy, maturity, aptitude to germinate) (Larpent, 1976;Singh and Rathod, 2002; Rao et al., 2006). The germination test is realized to determine which proportion of seeds after stocking will germinate in favorable conditions and will produce normal seedlings capable of developing mature plants for their reproduction (Rao et al., 2006). In this fact, there are many tests the most used of which are the bio-chemical and germination tests. The groundnut germination is aboveground. The reservations in the cotyledons dwindle as they ensure the vigorous growth to the seedlings. The pivoting root is in general well developed and the secondary roots bear nodosities containing nitrogen fixative bacteria (Diaw, 1999).During this activity we are going to lead observations as for the germination tests of groudnut seeds. We will put the germinative faculty in an obvious place that is to say the percentage of seeds likely to produce within a given time healthy and viable seedlings, 75% is generally an acceptable rate.
