A total of forty-nine recombinant inbred lines were evaluated for 16 traits using simple lattice design. All the measured over locations showed highly significant differences among except fertile tiller per plant, while x location interaction effect was most measured. Grain yield highest phenotypic coefficients variation (PCV) (26.36%) followed by above ground biomass (23.16%), remaining low (&...

In order to investigate path analysis and study correlations among 16 agronomic traits, 49 Iranian and foreign rice entries were evaluated in a simple lattice square as experimental design with 2 replications at research farm of Tonekabon agricultural college in 2001. Analysis of variance showed significant difference among genotypes for all the studied traits (p<0.05). Phenotypic and genotypic...

Wheat (Triticum aestivum L. emend. Thell.) grain yields are highly dependent upon the number of spike-bearing tillers produced per plant. Salinity, drought, and other environmental stresses can greatly affect the development and viability of tillers. We determined the effects of soil salinity on the occurrence and rate of tiller development and the incidence of tiller abortion in spring wheat c...

oroginal article tiller is a handy multi – a purpose tractor is used in agriculture. the noise emitted from tiller may be seriously affected auditory system users. the purpose of this study was to evaluate the exposure to noise in operators of this device. in this study 36cultivator tiller was examined. measurement of sound is based in iso 5131-1996 and iso 7216 standard and was conducted in in...

Sward structure affects herbage growth, pasture species dynamics, and herbage utilization. Defoliation management has a major impact on sward structure. In particular, tiller size-tiller density compensations allow for the maintenance of herbage growth. Tiller size and tiller density are determined by several major morphogenetical components. Defoliation affects these morphogenetical components...

Background: Heat-shock protein A2 (HspA2) is a testis-specific member of the HSP70 family known to play a critical role in spermatogenic cell differentiation. HSPA2 is correlated with sperm maturity, function and fertility, and diminished expression of HSPA2 results in abnormal sperm maturity and infertility. The aim of this study was to assess maturity of ejaculated spermatozoa via comparing p...
