An interspecific somatic hybrid between Actinidia chinensis and Actinidia kolomikta and its chilling tolerance

Protoplasts isolated from cotyledon-derived callus of Actinidia chinensisPlanch. var. chinensis (2N=2x=58) were fused with mesophyll protoplasts of Actiniadia kolomikta(Maxim. et Rupr.) Maxim (2N=2x=58) using a PEG method. Plantlets were regenerated from the fusion product clone 11. RAPD analyses, chromosome numbers of root tip cells and fluorescence peak position of leaf nuclei confirmed that clone 11 was an interspecific somatic hybrid (2N=4x=116) between A. chinensis and A. kolomikta. The chilling tolerance of the somatic hybrid was tested with in vitro leaves at low temperatures. Based on data of leaf thickness, electroconductivity, proline levels, malondialdehyde content and activity of superoxide dismutase, dendrogram cluster analysis suggested that the interspecific somatic hybrid was similar to A. kolomikta, and might have a higher capacity of cold resistance than A. chinensis.

东北典型森林土壤呼吸的模拟——IBIS模型的局域化应用

集成生物圈模拟器(IBIS)将陆地生态系统的生态学过程与相关的生物物理和生理学过程统一起来,代表了生态系统碳循环模拟模型的研究方向。将IBIS-2.6进行适当改造用于中国东北地区的6种典型森林类型(红松林、落叶松林、杨桦林、硬阔叶林、蒙古栎林和杂木林)的土壤呼吸、根际呼吸和异养呼吸估算,并以实测数据作验证。2004-2005年土壤呼吸、根际呼吸和异养呼吸年通量的模拟结果与实测值吻合较好,模拟偏差变动范围分别为:-5%-21%、-2%-16%和-16%-45%。土壤呼吸模拟值与实测值之间的差异不显著(P0.05),两者间的相关系数以杂木林最低(0.362)、硬阔叶林最高(0.917)。除了春末夏初的土壤呼吸迅速升高过程外,模型能较好的捕捉土壤呼吸的季节动态。研究为IBIS模型的局域化应用奠定了基础,并表明经过改造的IBIS可以用于特定的森林生态系统水平的土壤呼吸模拟估测。
