Midday leaf CO2 exchange rate (CER), concentration of chlorophyll (Chl) and soluble protein and activity of the primary enzymes involved in leaf photosynthesis and sucrose metabolism were determined during leaf ontogeny for sugarcane plants grown at ambient (360 mmol mol ) and double-ambient (elevated, 720 mmol mol ) CO2. Although leaf CER of both CO2 treatments increased and was highest at 14 ...

According to the importance and diversity of Chenopodium album, Cynodon dactylon and Amaranthus retroflexus in safflower fields and significant role of safflower (Carthamus tinctorius L.) as an oil seed, an experiment was conducted using CRD based factorial design with three replications to study the allelopathic effects of root and shoot extracts of these weeds on germination and early growth ...

Feeding trials were conducted for 28days to evaluate the nutritional value of Neem (Azadirachta indica) leaf meal on the performance and economics of deep litter managed finisher broiler production. The neem leaves were harvested, air dried and milled to become neem leaf meal. It was included in the broiler finisher diets at 0,2.5,5.0,7.5 and 10% levels respectively. One hundred and fifty (150)...

Task-space control is well studied in modeling speech production [1, 2, 3, 4]. Implementing control of this kind requires an accurate kinematic forward model. Despite debate about how to define the tasks for speech (i.e., acoustical vs. articulatory), a faithful forward model will be complex and infeasible to express analytically. Thus, it is necessary to learn the forward model from data. Arti...

background: low birth weight (lbw) is one of the major determinants of neonatal survival as well as postnatal morbidity. objective: the main objective of the present study was to determine neonatal mortality rate (nmr) in lbw infants in yazd, iran. materials and methods: in a prospective-cohort study, all births in the maternity hospitals of yazd, iran in 2004 were evaluated and mortality rate ...

Pruning is crucial to balance productivity and fruit quality in blueberry orchards. Slight, conventional and severe pruning treatments were applied on 4and 5-year old bluberry plants cultivar ‘Brigitta’ to evaluate their effect on yield, leaf area, gas exchange and fruit load as driver of fruit quality traits. Yield and berries per plant decreased with increasing pruning severity, whereas canop...

UV-B radiation and EOD light (EOD) quality has both signaling and damaging effects based on the dosage and time of exposure. At highland areas UV-B decreases crop productivity and also light quality increase at high elevation area but EOD light quality effect was not researched based on altitude. Therefore, in the present study a field experiment was conducted to investigate the effects of UV-B...

Neon flying squid Ommastrephes bartramii and jumbo Dosidicus gigas are two important commercial ommastrephid species in the Pacific Ocean. As short-lived marine species, squids highly susceptible to changes climate environments. According samples collected from northwest southeast Ocean different years, we explored growth characteristics of these terms their mantle length (ML) distribution rela...
