The reproductive tract of the male Cape porcupine is morphologically and histologically similar to that of New World hystricomorph rodents. Males are reproductively active throughout the year and attained sexual maturity (complete spermatogenesis) at an age of 8-18 months. Testes weight, epididymides weight and seminiferous tubule diameter attained asymptotic values at the age of 23-30 months. ...

seven maize inbred lines were crossed in a complete diallel cross design at the seed and plant improvement institute, karaj, iran, during the 2006 growing season. the parents and 42 f1 hybrids were grown in the research field of islamic azad university of firoozabad, firoozabad, iran, using a randomized complete block design (rcbd) with three replications, during the 2007 growing season. the ha...

Morpho-physiological and biochemical changes in developing cucumber (Cucumis sativus L) seeds were monitored under both open field (E1) protected environments (E2) during 2019 at ICAR-IARI, New Delhi. Fruits developed from hand pollinated flowers, Pusa Barkha Uday varieties harvested five-day intervals. The environment influenced days to maturity development of fruit and/or seed. Irrespective v...

the evaluation of gene bank germplasm collection for morpho-physiological traits is important in the breeding programs. although phenotypic variation was considered, it is likely that this phenotypic variation is largely genetic and therefore directly useable for breeders, especially for those traits with high heritability such as heading and maturity time, plant height, kernel number and weigh...

The bone microstructure of extinct animals provides a host information about their biology. Although the giant flightless dromornithid, Genyornis newtoni, is reasonably well known from Pleistocene Australia (until its extinction 50–40 Ka), aside various aspects skeletal anatomy and taxonomy, not much current study investigated histology fifteen long bones (tibiotarsi, tarsometatarsi femora) to ...

Climate change is expected to aggravate feed and food safety problems of crops; however, quantitative estimates are scarce. This study aimed to estimate impacts of climate change effects on deoxynivalenol contamination of wheat and maize grown in the Netherlands by 2040. Quantitative modelling was applied, considering both direct effects of changing climate on toxin contamination and indirect e...

The patterns of neurological development, as indicated by electroencephalographic (EEG) activity, are similar in different species. EEG activity is absent (isoelectric) initially. It then shows intermittent spikes followed by longer more sustained epochs that are separated by isoelectric periods. Thereafter, a continuous undifferentiated EEG appears and this finally differentiates into alternat...

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...

Despite the attainment of several adult cranial dimensions relatively early in childhood, skeletal maturity and, by consequence, adult form are typically defined by the eruption of the third molars around 17 years of age. This in turn serves as the division between subadults and adults, which is then applied to population studies of biological variation. Specifically, comparative data sets of a...
