Selecting appropriate donors and acquiring information about the genetic basis of inheritance is essential for breeding programs. In this study, a diallel cross was produced by crossing 15 progenies with five commercial lines wide diversity different rice traits (grain yield, plant height, days to flowering, panicle blast, brown spots, leaf scald, grain discoloration) in an incomplete design. T...

Different physicochemical tests have been used over time in the Oryza sativa species for study of industrial and culinary properties. In this study, nine attributes were compared: amylose content, total whiteness, thousand grain weight, length width, gelatinization time, apparent water absorption, expansion ratio, temperature. However, there is no single attribute that allows defining concept “...

در این مقاله، هدف طراحی و ساخت سامانه تشخیصی پروب لانگمویر جهت اندازه ­گیری پارامترهای پلاسما دستگاه گداخت به ­روش محصورسازی الکترواستاتیکی اینرسی ایران (IR-IECF) به­ منظور مشخصه­ یابی چشمه‌­ی پلاسمایی می‌­باشد. بدین‌­منظور، یک برای اندازه‌­گیری مختلف از جمله دمای الکترون­، چگالی الکترون، یون، پتانسیل ساخته شده است. با نظر گرفتن مشخصات چشمه IR-IECF، الکترود مورد استفاده مفتول جنس تنگستن قطر طول...

It has been reported that the neonatal administration of monosodium glutamate (MSG) in rodents produces lesions of the arcuate nucleus and the ventromedial nucleus of the hypothalamus and results in obesity in adulthood . Though there are a large number of reports using MSG-treated animals, most of them deal with neuronal and neuroendocrinological pathophysiology within the central nervous syst...

As algas são fontes promissoras na elaboração de bioestimulantes, capazes afetar o crescimento vegetais, aumentando a eficiência nutrientes e incrementando resistência plantas estresses abióticos. Objetivou-se avaliar biomassa área foliar dois cultivares arroz utilizando extrato água doce aplicado em diferentes estádios vegetativos. O experimento foi conduzido sob delineamento inteiramente casu...

O Brasil cultiva o eucalipto desde início do século XX e com desenvolvimento da eucaliptocultura, verifica-se ao longo dos anos uma expansão dessas áreas plantadas para outras regiões país, em que fortes tensões ambientais podem impactar negativamente a sobrevivência e/ou crescimento destas espécies. Neste sentido, objetivo deste trabalho foi avaliar desempenho fotossintético as trocas gasosas ...

The most direct approach for measuring the exchange of biogenic volatile organic compounds between terrestrial ecosystems and the atmosphere is the eddy covari-ance technique. It has been applied several times in the last few years using fast response proton-transfer-reaction mass spectrometry (PTR-MS). We present an inde-5 pendent validation of this technique by applying it to measure the wate...

Interest in arcobacters in veterinary and human public health has increased since the first report of the isolation of arcobacters from food of animal origin. Since then, studies worldwide have reported the occurrence of arcobacters on food and in food production animals and have highlighted possible transmission, especially of Arcobacter butzleri, to the human population. In humans, arcobacter...
