Plant breeding programs in local regions may have genetic and phenotypic variations that are desirable and shape adaptability during the establishment of local populations. Despite the characterization of genetic population structures in various kinds of populations, the effects of variations in phenotype on agro-economical traits currently remain unclear. In the present study, we evaluated phe...
thirty-three M7 soybean mutant lines which originated by γ ray (co-60) from cultivar L17 irradiated with doses150, 200 and 250 Gray (absorbed dose), L17 cultivar and two commercial cultivars Clark (CL) and Williams (WI) were evaluated in view of some agronomical and morphological traits under completely randomized design with three replications. In M7 mutant lines all traits except number of s...
Four new species of Anastrepha Schiner were collected in McPhail-type traps hung in trees in a natural reserve and in commercial papaya orchards in Linhares, Espírito Santo state, Brazil. They are described and named herein as follows: Anastrepha atlantica n. sp., Anastrepha glochin n. sp., Anastrepha linharensis n. sp. and Anastrepha martinsi n. sp. Only the latter was collected in traps hung ...
any change in the refractive index of a laser active medium can lead to serious degradation of beam quality, laser beam modes, laser performance and variation in the intensity distribution. alteration in the refractive index of laser active medium is especially notable in high power lasers. it is clear that in the laser beam production, the pumping agent induces a great amount of heat which...
BACKGROUND Neonectria ditissima is one of the most important fungal pathogens of apple trees, where it causes fruit tree canker. Information about the amount and partitioning of genetic variation of this fungus could be helpful for improving orchard management strategies and for breeding apple cultivars with high levels of genetically determined resistance. In this study single-spore Neonectria...
it is not possible to understand developments of a country’s culture and civilization without knowing his believes and myths. whether it is north or south, east or west, planes or mountains, sahara or deserts, here in iran every corner includes valuable and precious treasures which are known all over the world, and cultural – historical objects which are found here adorn all well known museums...
abstract when in administrative law the matter of administrative offences are raised, these offences would have legal nature if they are force able, some of these offences are related to administrative law, where as some other pelts are common in civil or penal law. the current research intends not only to consider the concept and foundation of administrative execution rules but also compares...
Anzali International Wetland located on the southwestern shore of the Caspian Sea possess a strategic role in establishing the ecological balance between animals and birds owing to its unique features. The wetland acts as a natural reproduction and rehabilitation ground for several groups the Caspian Sea fishes. It also serves as a habitat and spawning ground for the Caspian Sea migratory fish ...
The Japanese chestnut (Castanea crenata) carries resistance to Phytophthora cinnamomi, the destructive and widespread oomycete causing ink disease. The European chestnut (Castanea sativa), carrying little to no disease resistance, is currently threatened by the presence of the oomycete pathogen in forests, orchards and nurseries. Determining the genetic basis of P. cinnamomi resistance, for fur...
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
