Relationship between Meta-Technology Ratios and Varietal Differences in Date Production (Case Study of Sistan and Baluchestan, Iran)

This paper uses the concept of Meta-frontier to investigate the relationship between Meta Technology Ratios (MTR) and different varieties in datepalms including; Mazafati, Rabi and Zardan that are produced widely in Sistan and Baluchestan province of Iran. We used a stratified sampling of 300 date farmers of this province in 2010, 2011 and 2012 and estimated a stochastic production frontier usi...

Performance of laying hens fed diets containing DAS-59122-7 maize grain compared with diets containing nontransgenic maize grain.

An experiment using 216 Hy-Line W-36 pullets was conducted to evaluate transgenic maize grain containing the cry34Ab1 and cry35Ab1 genes from a Bacillus thuringiensis (Bt) strain and the phosphinothricin ace-tyltransferase (pat) gene from Streptomyces viridochromogenes. Expression of the cry34Ab1 and cry35Ab1 genes confers resistance to corn rootworms, and the pat gene confers tolerance to herb...

Absence of Epistasis for Grain Yield in Elite Maize Hybrids

ABSTRACT Measures of epistasis in maize hybrids have been estimated by (i) triple-test crosses, (ii) making comparisons Certain maize (Zea mays L.) inbred lines are more successful than of single, three-way, and double cross hybrids, or (iii) others in forming elite hybrids. This study was conducted to determine measuring variance components (Hallauer and Miwhether epistatic interactions play a...

Distribution of Abscisic Acid in Maize Kernel during Grain Filling.

The distribution of abscisic acid (ABA) within maize (Zea mays L.) kernels was studied in kernels from nontreated plants, from plants in which assimilate supply had been altered by source/sink manipulations, and in kernels cultured in vitro on ABA-free media. Prior to growth of the embryo, both the pedicel/placento-chalazal complex and the endosperm contained high concentration of ABA; however,...
