Abstract: The purpose of this experiment was to compare biodiesel to other fuels. The ecotoxicity of biodiesel was estimated‚ along with that of other biofuels through the germination of seeds in the presence of different concentrations of fuels. This resulted in biodiesel having an average of 79.4% germinated seeds in a 10% solution of fuel‚ compared to other fuels whose percentage of germinated seeds decreased with higher concentrations of fuel. In addition‚ biodiesel was also synthesized and

EFFECT OF ORGANIC AND INORGANIC FERTILIZER ON OKRO CHAPTER ONE (1) 1.1 INTRODUCTION Okra was domesticated in West and Central Africa (Cobley and Steele‚ 1976) and known as ‘Okro’ in the Anglophone African countries as a fast growing common annual vegetable widely consumed in Africa (Schippers‚ 2000). It is one of the numerous vegetable crops cultivated in Nigeria (Anon‚ 1989) where a total of 1 – 2 million hectares

effects of UV-C radiation on Brassica Rapa. Brassica Rapa commonly known as field mustard because of its close relationship to mustard and cabbage.(1) this plant has proved to be a great plant for scientific research due to its fast and successful germination period of 1-3 days. Sunlight is a necessary factor for photosynthesis to occur. Plant growth needs the suns UV light to proceed‚ but at what point can UV exposure become detrimental to plant morphology? Research indicates most damaging effects to

Due to diverse medicinal applications it is over-exploited and facing local extinction. It has been affirmed as endangered plant by IUCN. Basically the plant is monocot having very low germination capacity‚ (0.001%)‚ and life span is also very short just 2-3 months‚ conventional propagation is very limited and also slows since one tuber produce only one plant at a time‚ besides this plant is the richest source of colchicine‚ the high priced

Catherine Rameau2* & Soizic F. Rochange1* A carotenoid-derived hormonal signal that inhibits shoot branching in plants has long escaped identification. Strigolactones are compounds thought to be derived from carotenoids and are known to trigger the germination of parasitic plant seeds and stimulate symbiotic fungi. Here we present evidence that carotenoid cleavage dioxygenase 8 shoot branching mutants of pea are strigolactone deficient and that strigolactone application restores the wild-type branching

a spot in nature. I am trying to see which one of these plants inhibits the germination of radish seeds the most. Putnam (1984) reported that eucalyptus species released volatile compounds such as benzoic‚ cinnamic and phenolic acids‚ which inhibit growth of crops and weeds growing near it. Eucalyptus is a widely well-known allelopathic plant. I believe that Eucalyptus will allow the least amount of germination of radish seeds between Eucalyptus‚ Lemon‚ and a control. Allelopathy Lab
