Diameter at the crown base was subtracted from each measured stem diameter so that the transformed diameter at crown base is zero which provides compatibility with stem profile equations while maintaining tree stem profile. Three different taper functions were fitted to the transformed data and compared in respect of their ability to predict upper stem diameters, volumes and heights at different points along the stem. Equations, derived from the taper functions modified for the height up to the crown base, are also given in the appendix to predict height at a specific diameter and volume between two specified heights.","PeriodicalId":446148,"journal":{"name":"South African forestry journal","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134202219","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The species was introduced from Australian rain forests and planted extensively in the southern Cape forests since 1909. It has since become well established in the forests, and invaded open areas outside the forest. However, it is also a useful and valuable timber tree which contributes more than 60% of both the timber volume and revenue obtained from the forest. A Blackwood Group System was established in the forest since 1968 in which the tree was planted in pure stands in the forest gaps caused by the felling of large trees. This study comprised various investigations to assess the invasion status of the species in the forests and to determine under what conditions it poses a threat to the forest. The results show that A. melanoxylon occurs in all the main forests throughout the southern Cape. It has the characteristics of an aggressive invader plan...","PeriodicalId":446148,"journal":{"name":"South African forestry journal","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126956826","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A follow-up survey was conducted on one of the nurseries in 1995. The main objective was to determine whether the incidence differed significantly between nurseries and tree species, and whether any differences could be explained. The eucalypt seedlings had a low incidence of ectomycorrhizal infection, while the ectomycorrhizal status of pine seedlings increased with age, sometimes to high levels, but varied with tree species and nursery. The results for the pine seedlings were modelled by fitting logistic regression models. The significance and implications of the survey results are discussed.","PeriodicalId":446148,"journal":{"name":"South African forestry journal","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125796983","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An analysis of variance was carried out for each wood property to test the interaction between site and clone. For each clone a linear regression of the individual property value on the mean of all clones for each site was computed as a further measure of clone-by-site interaction. Both analyses indicated that genotype-by-environment interaction does exist for some clones and that it is applicable to all the wood properties considered except fibre length. However, clones showing sensitivity to changes in the environment for a particular wood property did not necessarily show sensitivity in the case of other wood properties. In other words, no clone could be singled out for showing sensitivity towards changes in the environment for all its ...","PeriodicalId":446148,"journal":{"name":"South African forestry journal","volume":"194 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122579671","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
