Indirect organogenesis from leaf explants of Eucalyptus benthamii x Eucalyptus dunnii and shoot multiplication
Background In Brazil, especially in the Southern region, stresses caused by cold and eventual frost are those that exert the most negative effect on the productivity of Eucalyptus spp. The genetic transformation techniques may contribute to forestry improvement programs in order to obtain genotypes expressing new interesting characteristics. They allow shortening the long breeding cycles and av...
متن کاملGrowth stress in Eucalyptus dunnii
Growth stress in 9-y-old plantation-grown Eucalyptus dunnii was assessed by measuring longitudinal growth strain. Strain varied considerably (370–1560 μm–1) and was sufficiently heritable (h2 = 0.3–0.5) that tree breeding may be an effective way to reduce the incidence of growth stress in this species. Although the formation of longitudinal growth strain appears to be under strong genetic contr...

متن کاملEffects of Temperature and Season on In Vitro Establishment and Shoot Multiplication of Picea abies (L.) H. Karst
Plant propagation originated from the mature tissues is the most desirable method in producing clonal plants, however microbial contamination usually is the main concern during regeneration processes. Moreover, commercial production of plants using clonal propagation is considered as high throughput method due to the removal of seasonal barriers, lower cost of production with higher yield wh...
