| dc.description | From the ancient of the world, the human being and animal life as whole are dependent to greatey degree on the plant kingdom. The plant kingdom supplies us with food, fuel, fodder, shelter, wind breaker and provides raw material for clothing, medicine. They also provides acidic substance e.g. tartaric acid, oxalic acid, citric acid, celicilic acid, butyric acid and provides gum substance such as lignin, citin, pectin, latex and provides us dying substance e.g. khayer, tarmaric, jafran, mahedi, etc and provides us protienious substance e.g. mithonine, tryptophan, valine, isopropine, histidine, lysine which essential amino acid only geting from plant. Some plant supplies us. mineral substance e.g. Ca, Mg, Fe, Co, Cl, K, Mn, Mo, Zn, S, N, etc which is essential to build human animal body. The vital part of the plant is carbohydrate (CHO) which contains galactose, maltose, starch, cellulose, sucrose, and fructose, supplies energy in human animal body. Some plant use as pesticide i.e. leaf of biskatali, neem, tobacco, datura, dust of chili, wood ash etc. We get lipid substance such as triacyl glycerol, phospholipid, fatty acid, wax etc. Some provides us oil substance, example mustard oil, soybean oil, sunflower oil, linseed oil, veranda oil and palm oil etc that contain energy, taste and protect the skin membrane, maintains the temperature of the body. | en_US |
| dc.description.abstract | The allelopathic effects of some weeds on germination and growth of rice and mustard seedlings with their chemical investigation were conducted in the laboratory.This study was performed on naturally occurring growth factors in. aqueous extracts of some common weeds viz. Aryl Leersia hexandra), Jaina (Fimbristylis miliacea), Sushnisak (Marsilea quadrifolia), Masurchana (Vicia hirsuta), Tita begun (Solanum nigrum) and Bankapi (Gnaphalium affine) with the attempt for chemical investigation on effective extracts. The boiled and unboiled extracts' of all the weed species prepared from whole plant were used for treating seeds of rice and mustard along with water as control. Boiled and unboiled extracts of all the weed species significantly reduced and delayed germination of rice and mustard seeds compared with control. The effect of unboiled extract ofJaina showed the lowest germination (82.7 %) in rice seed. But the unboiled extract of Aryl mostly inhibited the root and shoot length of rice seedlings. The effect of unboiled extract of Tita begun showed the lowest germination (50.6 %) in mustard seed and the unboiled extract of Tita begun inhibited the root and shoot length of mustard seedlings. The root and shoot length ofrice and mustard were reduced in presence of all the weed extract. The thin layer chromatography (TLC) examination of crude extract of Aryl (Leersia hexandra showed four separate compounds at hexane: ethyl acetate (10:1, v/v) and the crude extract of Tita begun (Solanum nigrum) also detected four separate compounds at hexane: ethyl acetate (10:1, v/v). | en_US |
