Nematogenesis, the production of stinging cells (nematocytes) in Cnidaria, can be considered as a model neurogenic process. Most molecular data concern the freshwater polyp Hydra, in which nematocyte production is scattered throughout the body column ectoderm, the mature cells then migrating to the tentacles. We have characterized tentacular nematogenesis in the Clytia hemisphaerica hydromedusa...

abstract an experiment was conducted to study growth analysis and evaluation of change in simple non- structural carbohydrates (sucrose, glucose and fructose) during bulb formation of ghermez azarshahr , zargan, safid naishaboor and safid qom cultivars in randomized complete block design containing three replications. seeds were sown in nursery in early february and seedlings were transplanted ...

in order to study the effects of different levels of animal manure and bulb weights on growth criteria, yield components, seed yield and essential oil yield of caraway, an experiment was conducted as factorial based on a randomized complete block design with three replications at the agricultural research station, ferdowsi university of mashhad, during two growing seasons of 2012-2013 and 2013-...

Meteorological data (1993 to 2004) from 2 public weather stations in Phoenix, Arizona, and Athens, Georgia, were analyzed with test day milk yield data from herds near weather stations to identify the most appropriate temperature-humidity index (THI) to measure losses in milk production due to heat stress in the semiarid climate of Arizona and the humid climate of Georgia. Seven THI with differ...

Garlic (Allium sativum L.) is an important vegetable crop throughout the world. In Greece there are many areas which have specialized in garlic cultivation through the last decades, considered the main production areas. However, despite the significance of garlic as a food product and the high annual income of this crop, there is a decreasing trend in total cultivated area in Greece, and the lo...

introduction drought stress reduces plant growth by affecting various physiological and biochemical processes, such as photosynthesis, respiration, translocation, ion uptake, carbohydrates, nutrient metabolism and growth promoters. garlic (allium sativum l.) is an annual bulb crop that has been cultivated since ancient times and was used as a spice and condiment for many centuries. garlic is an...
