Brassinosteroids (BRs) and Gibberellins (GAs) are two classes of plant hormones affecting plant height (PHT). Thus, manipulation of BR and GA levels or signaling enables optimization of crop grain and biomass yields. We established backcross (BC) families, selected for increased PHT, in two elite maize inbred backgrounds. Various exotic accessions used in the germplasm enhancement in maize proj...

Temperature changes occur in nature faster than other stressors. Plants due to inability to move and change their position, are exposed to extensive variations in daily or seasonal temperature, and therefore, should quickly and effectively adapt to temperature stress. In order to study the effects of heat stress on physiological traits of forage maize hybrids, a factorial split plot experiment ...

Mitochondrial DNA (mtDNA) insertions into nuclear chromosomes have been documented in a number of eukaryotes. We used fluorescence in situ hybridization (FISH) to examine the variation of mtDNA insertions in maize. Twenty overlapping cosmids, representing the 570-kb maize mitochondrial genome, were individually labeled and hybridized to root tip metaphase chromosomes from the B73 inbred line. A...

to study the effects of sowing dates, irrigation intervals and different cultivars on sugar beet root rot disease management and its quality and quantity yields, an experiment was conducted in a split- factorial based on randomized complete block design with four replications in the field of sugar factory jame. two irrigation intervals: eight days and 16 days were allocated in main plots, and d...

dehghan (ksc 400) is an early-medium maturity grain maize hybrid that has been developed from a cross between two inbred lines (ke72012/12×k1263/1). this cross was carried out in 1997, for the first time. the characteristics of dehghan hybrid were studied in different trials (preliminary, semi final, final and on farm trials) in several locations during 1997 to 2005. the mean grain yield of the...
