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.","PeriodicalId":22665,"journal":{"name":"The journal of sericultural science of Japan","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2001-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90488892","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}

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","PeriodicalId":22665,"journal":{"name":"The journal of sericultural science of Japan","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2000-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79999118","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}
