genetic diversity is essential in the implementation of breeding programs. in order to determine genetic diversity, factor analysis and heritability of yield and some morphological traits, 20 strawberry cultivars were studied at the agricultural station of kurdistan research center using a randomized complete block design with three replications. morphological characteristics such as number of ...

Field and laboratory studies were conducted to examine the relationship between foliar feeding damage caused by striped cucumber beetle, Acalymma vittatum (F.) (Coleoptera: Chrysomelidae), and yield of pumpkin, Cucurbita pepo L. (var. Spookie). In field trials in 1996 and 1997, plants were artificially infested with varying numbers of beetles at the cotyledon-, first-, second-, or third-leaf st...

peach genotypes showing notable fruit and tree traits were selected in ardabil and east azarbaijan provinces of iran. genotypes were grafted on seed rootstocks and cultured with 4×4 m spacing. traits such as tree growth habit, flowering, maturity, morphological and qualitative fruit characteristics were described in 15 peach genotypes using ibpgr peach descriptors during the 2005-2007 seasons. ...

Seasonal dynamics of total non-structural carbohydrates (TNC) in relation to the leaf-fruit ratio were measured over five years at different grapevine phenological stages in oneand two-year-old canes, trunks and roots of the cultivar 'Chasselas' (Vitis vinifera L.). Carbohydrates were mainly stored as starch in different parts of the grapevine during the growing season. Soluble carbohydrates re...

urban green space is a fundamental and attractive element of cities around the world all through the year. selecting species resistant to dryness is an essential decision for planting them in the urban green space in arid and semi-arid regions. one of the most important experiments to introduce new plants in new regions is phenology of different species. in this study, the phonological characte...
