近年,甘薯块根纵向裂伤与其它块根异常症状均常发生。块根裂伤不仅外形不佳,也影响耐贮性与加工性,显著降低了商品价值。最近,千叶县农业试验场以生育初期低温与裂伤关系为目的进行试验,指出低温是诱发的重要原因。但是笔者重复进行田间试验,并没有得到稳定的再现性。因此,本研究在人工控制气候的条件下,用一叶插栽培法进行严格
In recent years, sweet potato root tuberous longitudinal laceration and other abnormal symptoms often occur. Not only the appearance of root laceration poor shape, but also affect the storage and processing, significantly reducing the value of the commodity. Recently, Chiba Prefecture Agricultural Experimental Field to early stage of low temperature and laceration for the purpose of testing, pointed out that low temperature is an important cause of induction. However, the author repeated field trials and did not achieve stable reproducibility. Therefore, under the conditions of artificial climate control, the study was strictly carried out by single-leaf cultivation method
