Variability in wood properties of promising willow clones
The objective of the article is to investigate the variability in growth and wood properties of the willow clones. The growth and wood traits of four year old 21 clones willow clones were investigated. Analysis of variance showed that willow clones differed significantly for all the studied growth and wood traits. Among the growth parameters the maximum heritability value was shown by height wh...
متن کاملPlant Growth Hormones in Pinyon Insect Galls
BYERS J. A., BREWER J. W. & DENNA D. W. 1976. Plant growth hormones in pinyon insect galls. Marcellio 39, 125-134. Larvae of the midge Janetiella sp. near J. coloradensis Felt (Diptera: Cecidomyiidae) cause galls at the base of young needles of pinyon Pinus edulis Engelm. Bioassays of extracts from these galls contained as much as 17 times more auxin activity and as much as 21 times more gibber...
متن کاملPhotosynthetic efficiency of Clusia arrudae leaf tissue with and without Cecidomyiidae galls.
Leaf galls induced by a still undescribed new species of Cecidomyiidae (Diptera) are frequent on leaves of Clusia arrudae Planchon & Tirana (Clusiaceae) in the rupestrian fields at 1400 m a.s.l. in Serra do Cipó, Minas Gerais, Brazil. Galls were 7.1 ± 0.7 mm in diameter, one chambered with only one larva inside. Gall tissue is green and soft. Assessments of photosynthetic capacity using chlorop...
متن کاملWillow System Demonstration
Dealing with damage that arises during operation of networked information systems is essential if such systems are to provide the dependability required by modern critical applications. Extensive damage can arise from environmental factors, malicious actions and so on, and in most cases it is impractical to mask the effects of such damage using typical redundancy techniques. Reconfiguration is ...
متن کاملThe Willow Survivability Architecture
Introduction The Willow architecture provides a comprehensive architectural approach to the provision of survivability [8] in critical information networks. It is based on the notion that survivability of a network requires reconfiguration at both the system and the application levels. The Willow notion of reconfiguration is very general, and the architecture provides reconfiguration mechanisms...
