Callus Induction on Sesame (Sesamum indicum L.) by 1-Naphthalene acetic acid and 2,4-Dichlorophenoxy acetic acid Hormones
Sesamum indicum L. belongs to family pedaliaceae that these family, including 60 species. Sesame is the most important oil-seed crop of semi-arid tropics and a source of high quality cooking oil and protein. In recent years, plant tissue culture techniques has become a powerful tool for the propagation of many plant species. In this research […]
Study on biological spectrum of Madhav National Park, Shivpuri Madhya Pradesh India
The present study was carried out to understand the Biological spectrum of the flora of Madhav National Park. A total of 65 species, 59 genera belonging 41 families were estimated from the study area. Leguminaceae was the dominant family (10.60%) recorded under present investigation. The major class of life form was found to be Phanerophytes […]
New report of Capoeta damascina (Teleostei: Cyprinidae) from aqueducts and springs in Kerman province, Iran
This study investigated fish fauna identification of Zarand and Kouhbanan in Kerman province to reveale the range extension of Capoeta damascina, Siahmahi, in northwest of Kerman basin aqueducts and springs. In this study totally 39 sites in Zarand and Kouhbanan were investigated based on having or not having fish species. Sampling was carried out in […]
Temporal dynamics of phytoplankton communities and their responses to environmental factors in Grand-Lahou Lagoon, Ivory Coast, West Africa
Variations in physical-chemical factors, species composition, abundance and biomass of phytoplankton assemblages, as well as their responses to environmental factors, were investigated in Grand-Lahou Lagoon from June 2006 to February 2007 (Ivory Coast, West Africa). The hydrosystem and the growth of anthropogenic activities on its hillsides particularly favored the high rate of soluble reactive phosphate […]
Isolation and characterization of a sporless mutant in the white button mushroom (Agaricus bisporus)
Despite the long cultivation and importance of Agaricus bisporus, but efforts in breeding of this species are minimal. One of the major reasons for the little efforts is the life cycle. Because of the life cycle the cross cannot happen between single spores of different strains. So variation in Agaricus bisporus is very low and […]
Bio-ecology of Asian giant honeybee,Apis dorsata F. (Hymenoptera: Apidae) at arid, semi-arid and regions of South-Western Karnataka, India
India is one of the honey hubs, where large quantity of multifloral honey comes from the wild colonies of Asian giant honeybee, Apis dorsata Fabricius. Being an open nester, A. dorsata construct big sized comb and thrive well under diversified ecosystems by extending pollination services to various plant species. However, during its stay at arid, […]
Comparison on allowable use of Festuca ovina in semi-steppe and mountainous rangelands of Alborz and Zagros
Current research was carried out in selected sites of semi-steppe region including Badamestan (Zanjan), Firoozkooh (Tehran), Gharebagh (West Aazarbaijane), Zaghe (Lorestan), Ghavan- ban- hersin (Kermanshah), Alamot (Qazvin), Ghorveh (Kurdistan), Ser and Til Abad (Gholestan). Festuca ovina is a key and palatable species, having a considerable portion in rangeland yield. For this purpose, 40 similar species […]
Foraging and pollination activity of Musca domestica L. (Diptera: Muscidae) on flowers of Ricinus communis L. (Euphorbiaceae) at Maroua, Cameroon
To evaluate the impact of Musca domestica on fruit and seed yields of Ricinus communis, its foraging and pollinating activity were studied in Maroua, during two seasons of flowering (September – November 2010 and 2011). Treatments included unlimited inflorescences access by all visitors, bagged inflorescences to avoid all visits, and limited visits of M. domestica. […]
Revision of Crataegus monogyna Jacq.(Rosaceae) populations using RAPD marker in Iran
Crataegus monogyna, belongs to Rosaceae family and known as common hawthorn or single-seeded hawthorn. Crataegus monogyna is often divided into several infraspecefic taxa and or two or more species. Two varieties of this species is represented in Iran, Crataegus monogyna var. monogyna from northwest and Crataegus monogyna var. lasiocarpa from Hyrcanian region. In this survey […]
Foraging and pollination activity of Macronomia vulpina (Gerstaecker, 1857) (Hymenoptera: Halictidae) on Gossypium hirsutum L. (Malvaceae) flowers at Maroua, Cameroon
To evaluate the impact of Macronomia vulpina (Hymenoptera: Halictidae) on bolls and seeds of Gossypium hirsutum, its foraging and pollinating activities were studied in Maroua, during two seasons of flowering (August-October 2010 and 2011). Treatments included unlimited flowers access by all visitors, bagged flowers to avoid all visits and limited visits of Macronomia vulpina. Observations […]
