Early Selection of Improved Black Walnut Genotypes
Fine hardwood trees in the Central Hardwoods region of the United States are an important resource for the furniture, cabinetry, flooring, modular home, and paneling manufacturing industries. Consumers find wood from these trees to be very desirable because of quality factors such as grain, strength and color. To enhance wood production, tree improvement programs can address quantity and qualit...
متن کاملSomatic embryogenesis, micropropagation and plant regeneration of "Early Mature" walnut trees (Juglans regia) that flower in vitro.
Some walnut trees (Juglans regia L.) originating from central Asia display an early flowering phenotype. These "Early Mature" (EM) trees may produce flowers within months of germination. Secondary flowering waves are also observed within a growing season. Inflorescences may carry male, female and hermaphrodite flowers. Progeny obtained from selected EM trees were cultured in vitro to initiate c...
متن کاملEvaluation of some Phenological and Pomological Characteristics of Selected Walnut Genotypes from Shahroud-Iran
The first step in walnut breeding programs is to identify and evaluate superior genotypes of fruit trees. Hence, there are various walnut breeding programs in various areas of Iran. A study aimed to evaluate the morphological and chemical characteristics of selected superior genotypes of walnut was conducted in the Shahroud region in 2011-2012. The following genotypes were selected in this stu...
متن کاملMicropropagation of mature tree of Citrus limon
A protocol for in vitro cloning of mature plants of Citrus limon using nodal shoot segments has been developed. Three to four shoots were induced per axillary meristems on MS medium amended with 9 μM BAP. Repeated transfer of the initial explants for up to six passages on MS medium [having 50% of the original concentrations of NH4NO3 and KNO3, and supplement of 250 mg L (NH4)2SO4] with 0.22 μM ...
متن کاملMicropropagation of Elaeagnus angustifolia from mature trees.
Multiple shoots were obtained from nodal segments of mature trees of Elaeagnus angustifolia L. cultured on MS medium (Murashige and Skoog 1962) supplemented with 0, 0.88 or 2.22 micro M N(6)-benzyladenine. When nodal segments taken from the in vitro proliferated shoots were cultured under the same conditions, additional multiple shoots were obtained. Rooting of the in vitro propagated shoots wa...
