A preparatory study of leguminous plants on allelopathic potential was completed from January to June 2015. In laboratory conditions, entire plants of 12 leguminous plants at the blossoming stage were collected and ground into residue powder. The powders were measured by phytotoxicity on germination and development of barnyard grass (Echinochloa crus-galli (L.) Beauv.) by direct application in a Petri dish at the rate of 250 and 500 mg/Petri dish. Centrosema pascuorum cv. Cavalcade, Clitoria ternatea and Stylosanthes guianensis demonstrated the most phytotoxic impact on germination and seedling development of barnyard grass. The level of hindrance on germination at 500 mg/Petri dish was 86%, 98% and 98% respectfully. Macroptillium atropurpureum and Phaseolus lathyroides powders demonstrated the slightest phytotoxicity. Another trial was directed to test the powders on weed control in pot scale. Directed wet seeds were sowed in the pot for 10 days. Utilization of powder integrated with a water irrigation was included into the pot at the proportion of 250 and 500 kg./ha.

This work is licensed under the Creative Commons Attribution International License (CC BY). http://creativecommons.org/licenses/by/4.0/ Abstract Mucuna pruriens seed shells (abundantly available agricultural waste) were processed, treated and activated using 60% orthophosphoric acid for removal of congo red and malachite green from an aqueous solution. Its physicochemical properties and its removal efficiencies on the textile dyes were determined. The effect of particle size, adsorbent dose, initial pH of solution, adsorbate concentration and contact time on the process of adsorption was investigated. The equilibrium, kinetic and thermodynamic properties of the dyes removal were also investigated. The experi- mental data were modeled using linear regression method of analysis. The correlation coefficient was used as a criterion for model adequacy and acceptance. Sum of squares error was used to va- lidate the isotherm models. The pseudo second-order kinetic model was found to best correlate the experimental data. The intraparticle diffusion is not the only rate controlling step in the process.

  • G6PD Deficiency Food to Avoid Some of the Foods Commonly Eaten Around the World Can Cause People with G6PD Deficiency to Hemolyze
    G6PD Deficiency Food To Avoid Some of the foods commonly eaten around the world can cause people with G6PD Deficiency to hemolyze. Some of these foods can be deadly (like fava beans). Some others can cause low level hemolysis, which means that red blood cells die, but not enough to cause the person to go to the hospital. Low level hemolysis over time can cause other problems, such as memory dysfunction, over worked spleen, liver and heart, and iron overload. Even though a G6PD Deficient person may not have a crises when consuming these foods, they should be avoided. • Fava beans and other legumes This list contains every legumes we could find, but there may be other names for them that we do not know about. Low level hemolysis is very hard to detect and can cause other problems, so we recommend the avoidance of all legumes. • Sulfites And foods containing them. Sulfites are used in a wide variety of foods, so be sure to check labels carefully. • Menthol And foods containing it. This can be difficult to avoid as toothpaste, candy, breath mints, mouth wash and many other products have menthol added to them. Mint from natural mint oils is alright to consume. • Artificial blue food coloring Other artificial food color can also cause hemolysis. Natural food color such as found in foods like turmeric or grapes is okay. • Ascorbic acid Artificial ascorbic acid commonly put in food and vitamins can cause hemolysis in large doses and should be avoided. It is put into so many foods that you can be getting a lot of Ascorbic Acid without realizing it.

(FABACEAE) *Sarita A. Kukade and Jaikiran A. Tidke Laboratory of Reproductive Biology of Angiosperms, Department of Botany, Sant Gadge Baba Amravati University, Amravati 444602 (M.S.) India *Author for Correspondence ABSTRACT Dolichos lablab is an ancient legume crop widely grown throughout the world for its vegetable or pulse for human consumption or as animal forage or feed. It is a semi-erect, bushy, perennial herb, cultivated as an annual. It flowers during the months of September to February. Large numbers of small flowers are arranged in long recemes. Flowers open between 11.00am to 04.00pm. Anther dehiscence occurs before flower opening. The stigma becames receptive during 08.00am to 07.00pm on the day of flower opening. The stigma is wet, papillate and the style is solid. Pollen viability percentage in TTC was found to be 94.89%. The percentage of in vivo pollen germination was recorded as 38.80% which was found to be increased to 40.48 and 54.25% on the second and third day respectively. Flowers are visited by several insects. However, Xylocopa, ants, thrips, butterflies are the main visitors. Keywords: Dolichos Lablab, Pollen Viability, Pollen Germination INTRODUCTION Many flower visiting insects and other animals are engaged in a remarkable mutualism with the plants. As bees, butterflies and other pollinators forage for resources found within flowers, such as pollen, nectar or more rarely other substances such as scents or resins, their bodies contact sexual organs of plants (Waser, 2001).

Vietnamese: dây sắn, dậu mèo, dậu mèo rừng, dây sắn, dậu ngứa, dậu mèo lông bạc, ma niêu, mắc mèo Variety – Tropical: Climbing variety. Requires short days for flower and pod production. General description and special characteristics – Vigorous, vining, annual (sometimes biennial) legume. Vines may extend up to 18 m (19.7 yd) in length. Velvet bean originally came from China and eastern India where it was commonly grown as a green vegetable crop. Crop uses (agricultural) – Velvet bean is an extremely valuable crop for intercropping in cornfields, rehabilitating depleted land, and for controlling weeds in fallow croplands. It produces a trailing vine 3 to 8 m (10 to 25 ft) or more in length, and creates a very thick ground cover, making it an excellent mulch for eliminating serious weeds such as nutgrass, bermudagrass, and imperata grass. Velvet bean is also an important nitrogen fixing legume, able to fix high amounts of nitrogen at reported rates of 200 lbs/acre (228 kg/ha). Velvet bean is also known to repel nematodes when used in a crop rotation, although it is not resistant to nematodes itself.
