Study on the selection of high hardiness of rapid growth superior plant of Eucalypts
LIN Mu-jiu(Forestry Science and Technology Popularization General Station of Hunan Prov.,Changsha 410007,China)
The main characteristics and compositive selection based on cold resistance and hot resistance of the single plant of Eucalypts.The main selective reason based on the ecological reflection on the highest and lowest temperature in disaster of single plant of Eucalypts.301 plants were selected form 12 superior species including Eucalypts camaldulensis,E.dunnii,E.saligna×botryoides,E.benthanii and so on.148 plants were translated into clone utilization form the 301 plants. There were 30?000 hm~2 afforestation of Eucalypts clone species in Hunan, and then be introduced in Anhui,Jiangxi,Fujian,Guangxi,Guizhou,and Yunan.The results of afforestation showed that Eucalyptus has good hardiness and high inheritance capacity.
