Muscari armeniacum is one of the important ornamental cut flower in floriculture industry which native to Southern Europe, North Africa, Western Asia and Asia Minor. In this study, bulb explants (basal plate of bulb having meristem), bulb scales and leaf segments from in vitro derived bulblets were culture in Murashige and Skoog (MS) medium with different plant growth regulato...

Abstract Polyploidy induction could increase shallot bulb-size to raise consumer preference and local productivity. The research aimed obtain an effective method of polyploidy on callus onion ( Allium cepa ) var. Bima Brebes. experiment was consisted two experimental steps, which were polyploid the callus. A 1×1 cm treated by drops oryzalin with concentrations 0, 25, 50, 75, 100, 120 ?M. ploidy...

To explore the use of Caenorhabditis elegans and related nematodes for studying behavioral evolution, we conducted a comparative study of pharyngeal behaviors and neuronal regulation in free-living soil nematodes. The pharynx is divided into three parts: corpus, isthmus and terminal bulb, and pharyngeal behaviors consist of stereotyped patterns of two motions: pumping and peristalsis. Based on ...

Hair samples from beef cattle were examined to determine their response to feeding varying levels of protein and energy. Blood urea nitrogen (BUN) and nitrogen balance tests were also performed to provide a reference for comparison. Twenty-four weanling calves each weighing approximately 200 kg were equally divided into four groups and were fed the following percentages of the N.R.C. recommenda...

A shower cooling tower (SCT) operates without fill because of salt decomposition on the fill that leads to deterioration of conventional cooling tower performance. This study presents a two-dimensional mathematical model for energy and exergy analysis of multi-diameter droplets and air interaction along with the height of the forced draft SCT, to predict the exit condition of water droplet for ...

The method described by Rosenau 1 for injecting precise amounts of fluids into animals is excellent. In the practical application of this method certain difficulties have however been encountered, which, it is believed, can be overcome by improvements in the syringe herein described. The time reqtfired for removing the bulb of and measuring the salt solution into the syringe to wash i t out, af...

abstract nitrogen is a key nutrient in plant growth and it is necessary for amino acid synthesis. sulfur has very important role in the biosynthesis of the alliums flavor and pungency precursors and potassium improve crop yield and quality. in order to study the effect of ammonium nitrate and potassium sulfate on concentration some of the mineral elements in onion (allium cepa l. azar shahr cv....

Lateral inhibition in the olfactory bulb is mediated by circuits that involve reciprocal dendrodendritic connections between mitral and granule cells. Because of the properties of these connections and also because odor stimuli are not represented in an obviously topographic fashion, questions have been raised about whether the function of local inhibition in the olfactory bulb can be compared ...
