Leaf area information is required in various horticultural and physiological studies and it will be more useful if done via non-destructive methods. The objective of this study was to establish equations to estimate leaf area (LA) using length (L), width (W), fresh weight (FW), dry weight (DW), length × length (L2), width × width (W2), length × width (L×W), length + width (L+W), fresh weight × ...

Abstract Sire selection for beef on dairy crosses plays an important role in livestock systems as it may affect future performance and carcass traits of growing finishing crossbred cattle. The phenotypic variation found has raised concerns from meat packers due to animals with type characteristics. use morphometric measurements help understand the structures sire progeny selecting greater perfo...

The objective was to describe genetic parameters and genetic changes in litter sizes at birth and weaning (LB and LW, n =9081), birth weight (BW, n =11,896), weaning weight (WW, n =11,104), fleece weight and grade (FW and FG, n =8872), and staple length (SL, n =1805) of Polypay sheep. Direct heritability estimates from single-trait analyses were 0.11 for LB, 0.02 for LW, 0.17 for BW, 0.18 for W...

Kernel weight is important for plant breeders to select high productive plants. The determination of relationships between kernel weight and some fruit-kernel characteristics may provide necessary information for plant breeders in selection programs. In the present study, the relationships between kernel weight (KW) and 7 fruit-kernel characteristics: Fruit Length, (FL,), Fruit Width (FW) Fruit...

a study was conducted at the research station of department of horticultural science (tehran university, karaj) to evaluate the effects of water stress on yield, growth and some physiological parameters in iranian melon. the experiment was set out in a split plot design with three replicates. treatments consisted of factorial arrangement of three irrigation levels (starting irrigation at -50, -...

abstract coontail (ceratophyllum demersum) and watermilfoil (myriophyllum spicatum) are current submersed weeds in many fresh waters of iran. the excessive growth of these plants causes the reduction in utilization of water resources and making some ecological and economical damages in these areas. the aim of this study was to determine the response of two submerged aquatic weeds of coontail an...

Statistical properties of the static networks have been extensively studied. However, online social networks are evolving dynamically, understanding the evolving characteristics of the core is one of major concerns in online social networks. In this paper, we empirically investigate the evolving characteristics of the Facebook core. Firstly, we separate the Facebook-link(FL) and Facebook-wall(F...

data used  in this publication  is a part of a comprehensive  study was carried out jointly between  south  aquaculture  research  center  (siarc)  and  kuwait  institute  for  scientific research  (kisr)  on  silver  pomfret  (pampus  argenteus)  in  2003  to  2005.  the  study  was aimed to collect efficient data from two regions from biological and population parameters of this economically ...

Food losses (FL) and waste (FW) occur throughout the food supply chain. These residues are disposed of on landfills producing environmental issues due to pollutants released into air, water, soil. Several research efforts have focused upgrading FL FW in a portfolio added-value products energy vectors. Among most relevant advances, biotechnological these via fermentation has been demonstrated be...
