摘 要 ：在繁殖棚内昼夜施放ＣＯ₂，使棚内ＣＯ₂浓度保持在８００±１００μｌＬ－１，对三种澳大利亚园林植物：Ｃｈａｍｅｌａｕｃｉｕｍｕｎｃｉｎａｔｕｍ、Ｃｏｒｒｅａｒｅｆｌｅｘａ和Ｐｒｏｓｔａｎｔｈｅｒａｉｎｃｔｓａ进行插条试验。结果表明：高浓度ＣＯ₂处理的Ｃｈａｍｅｌａｕｃｉｕｍｕｎｃｉｎａｔｕｍ和Ｃｏｒｒｅａｒｅｆｌｅｘａ插条干物质重量和淀粉含量显著增加，使插条出根早、出根率高和根量多，据后４０ｄ的插条出根率分别比对照高２６．６％和３３．４％．然而，同样的ＣＯ₂处理对Ｐｒｏｓｔａｎｔｈｅｒａｉｎｃｉｓａ

Abstract:Cuttings of Chamelaucium umcinatum and Correa reflexa in the plastic chamber enriched with CO₂ both day and night at an average level of 800μl L-1 showed a significant increase of dry weight and starch content.In comparison with control,the short time of recovering of starch content to initial level and a progressive rise of starch content in high CO₂ treated cuttings resulted in the earlier rooting, higher rooting percentage and more roots. After cutting for 40 days,the rooting rates of the CO₂ enriched cuttings of Chamelaucium uncinatum and Correa reflexa were respectively 26.6% and 33.4% higher than that of the controls.However,the effect of CO₂ enrichment on cuttings of Prostanthera was inconspicuous,probably because these cuttings were insensitive to CO₂ treatment.
