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 کاملUtilização de Imagens de Sensoriamento Remoto de Alta Resolução para Realizar a Contagem de Copas em Povoamento de Eucalyptus spp
The present work aims at performing automatic tree crown counting in planted Eucalypt forests. High resolution remote sensing imagery and digital image processing using Lee Filters and the unsupervised classification algorithm ISODATA were used. The classification result that best extracted tree crowns was exported to a GIS for tree counting. The resulting number of trees was compared to the nu...

متن کاملبررسی و تعیین ترکیبهای شیمیایی اسانس برگ Eucalyptus stricklandii Maiden و Eucalyptus erythrocorys F. Muell.
نمونه های دو گونه اوکالیپتوس Eucalyptus stricklandii Maiden و Eucalyptus erythrocorys F. Muell. که در منطقه شمال خوزستان کشت گردیده در اواسط اسفند 1382 جمع آوری و به روش تقطیر با آب (طرح کلونجر) اسانس گیری و سپس نمونه توسط دستگاههای کروماتوگرافی گازی (GC) و کروماتوگرافی گازی متصل به طیف سنج جرمی (GC/MS) مورد تجزیه قرار گرفتند. ترکیبهای عمده در گونه E. stricklandii Maiden عبارتند از : 1,8-...
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...
