The prediction of mulberry (Morus alba L.) growth becomes important for changes in the mulberry cultivation system. To develop a mulberry growth model, the response of mulberry growth to different temperatures was investigated. Mulberry saplings were grown in phytotorons under sunlight at 3 diurnally fluctuating temperature conditions (34/22, 32/24, 30/26°C) which were a 28°C average daily temperature and at 2 constant temperatures (28, 32°C) in 1995, and at 4 fluctuating temperatures (33/19, 32/20, 30/22, 28/24°C) which were a 26°C average daily temperature and at one constant temperature (26°C) in 1996. The shoot length and leaf number were investigated every 10 days. Distribution of dry matter to each plant part was measured at the end of the treatment. Changes in shoot length were not different among temperature treatments and the rate of shoot elongation increased in the process of time during the treatments in 1995, but leveled off at the end of treatment in 1996. There were no differences in leaf number among the same average daily temperature treatments in either years, but the leaf number between 32°C treatment and the other average daily 28°C treatments in 1995 was significantly different at a 1% level. Shoot dry weight was not different among temperature treatments in both years. Therefore, fluctuating temperature conditions seemed not to affect mulberry growth as long as the average daily temperature was same. The leaf number seemed to be a superior index of mulberry growth.
桑树(Morus alba L.)生长预测对桑树栽培制度的变化具有重要意义。为了建立桑树生长模型，研究了桑树生长对不同温度的响应。1995年，桑树幼苗在3种日平均温度(34/22℃、32/24℃、30/26℃)和2种恒定温度(28℃、32℃)条件下生长;1996年，桑树幼苗在4种温度(33/19℃、32/20℃、30/22℃、28/24℃)下生长，日平均温度为26℃，1种恒定温度(26℃)条件下生长。每10 d调查一次茎长和叶数。处理结束时测定干物质在植株各部位的分布情况。不同温度处理的茎长变化无显著差异，1995年各处理的茎伸长率随时间的推移而增加，1996年处理结束后趋于平稳。相同日平均温度处理间叶片数无显著差异，但1995年32℃处理与其他28℃处理间叶片数差异显著(1%)。2年不同温度处理的茎干质量无显著差异。因此，在日平均温度相同的条件下，温度波动对桑树生长似乎没有影响。叶片数似乎是桑树生长的优越指标。

Plant transformation technology has become an indispensable tool for studying gene function in plant and for cultivar improvement (BIRCH, 1997; HANSEN and WRIGHT,1999). Many successful transf ormants of fruit trees have been reported (MATSUTA et al., 1993 and references therein). However, there are few reports on gene transfer systems for mulberry (Morus alba L.) trees by Agrobacterium (MACHII, 1990), by particle bombardment (MACHII et al., 1996; SUGIMURA et al., 2000) and by electroporation (SUGIMURA et al., 1999b). These authors showed that each transformation system was available for gene delivery into mulberry plant. However, whole plants developed from these transformed cells have not yet been obtained except for the case of development of the transformed plantlets from A. tumefaciens-inoculated leaf discs (MACHII, 1990). The limiting factors to practical transformation of mulberry plant may be a difficulty of regeneration and a low frequency of transformation. Many trials have shown that the mulberry is one of the species recalcitrant in regeneration. However, successful regeneration and organogenesis of mulberry plant from immature leaf cultures * Corresponding author 4 Present address: Horticulture Department , Southwest Agricultural University, Chongqing 400716, China
植物转化技术已成为研究植物基因功能和品种改良不可缺少的工具(BIRCH, 1997;HANSEN and WRIGHT,1999)。许多成功的果树转化已被报道(MATSUTA et al.， 1993和其中的参考文献)。然而，关于农杆菌(MACHII, 1990)、粒子轰击(MACHII et al.， 1996;SUGIMURA et al.， 2000)和电穿孔(SUGIMURA et al.， 1999b)。这些作者表明，每种转化体系都可以将基因传递到桑树植株。然而，目前还没有从这些转化的细胞中发育出完整的植物，除了从接种了A. tummefaciens的叶盘中发育出转化的植株(MACHII, 1990)。制约桑树实际转化的因素可能是再生困难和转化频率低。许多试验表明，桑树是再生中具有顽固性的树种之一。通讯作者4通讯地址:西南农业大学园林系，重庆400716
