The introduction of nanoparticles into seed germination and seedling growth of plants might have a significant impact and thus, it can be used for agricultural applications for better growth and yield. The purpose of this study was to compare the effects of silica and silver nanoparticles on seed germination and early growth traits as well as percent and rate of germination, root length, shoot ...

despite the importance of drought stress in early stage of growth and plant establishment, it has usually been neglected as selection criteria in breeding programs. therefore, a population of recombinant inbred line derived from the cross “babax/seri m82” and their two parents were studied. the experiment was conducted in two randomized complete block designs with two replications under osmotic...

background: as moringa peregrina is a valuable medicinal plant in traditional medicine, it is necessary to determine responses of this plant to salinity.  objective: to determine some biochemical and growth responses of moringa peregrina to salinity at the seedling stage. methods: this experiment was conducted in institute of medicinal plants-acecr, on base of factorial experiment as completely...

the objective of this study was to determine the inbreeding depression on growth traits in moghani sheep. pedigree information of 8836 animals collected during the years of 1987 to 2006 by moghani breed center in jafar abad moghan, were used for analysis. the base population year was 1988. analysis of the records was performed by asreml software. inbreeding depression was estimated as the regre...

the objective of the current study was to estimate the genetic parameters for body weight traits at different ages in iran-black sheep. data collected during a 24-year period (1984-2008) on body weight were used to model the growth trajectory and estimate genetic parameters. studied traits were birth weight (bw), weaning weight at 3 months of age (ww), 6 months weight (6mw), 9 months weight (9m...

In polygynous species, variance in reproductive success is higher in males than females. There is consequently stronger selection for competitive traits in males and early growth can have a greater influence on later fitness in males than in females. As yet, little is known about sex differences in the effect of early growth on subsequent breeding success in species where variance in reproducti...
