中文摘要 | 以四個萵苣(尖葉萵苣‘V-305’、葉萵苣‘V-155’、紅菲萵苣‘葉萵41’及皺葉萵苣‘LS-005’)為基礎,以評估33個萵苣品種耐熱性,以第三葉片在50°C水浴處理80分鐘能區分品種間葉片電解質滲漏率之差異。不結球萬荳如‘奶油164', ‘臺灣大葉白萵苣’、‘改良長葉白萵苣’、‘美國羅曼尼紅萵苣’、‘アカチマ紅葉甜萵苣’、‘蘿蔓157’、‘ERFANO-1’及‘嫩莖萵苣V-310’等品種之電解質滲漏率低於或相似於尖葉萵苣‘V-305’為對熱具有耐性之品種。結球萵苣如‘綠葉183’、‘美生73’、‘美生165’、‘美國大湖366 M. T. ’、‘美國大湖659 M. T. ’及不結球萵苣‘葉萵180’等品種之電解質滲漏率高於或相似於熱敏感的皺葉萵苣品種‘LS-005’。 |
英文摘要 | The heat-tolerance of four lettuce (Lactuca sativa L.) cultivars ('Leaf lettuce V-155', 'Sharp leaf lettuce V-305' , 'Leaf lettuce-41' Wrinkle-leaf lettuce LS-005') were evaluate by electrolyte leakage ratio. As Plug seedlings were 5-6 true leaf stage , the 3rd leaf of each cultivar were punched to 1cm round leaf disc and then placed 5 leaf disc in a water bath with 50°C , 80mins for testing electrolyte leakage ratio in order to distinguish heat-tolerant and heat-sensitive cultivars. The 3^(rd) leaf were more sensitive to distinguish heat-tolerant and heat-sensitive cultivars than 5th leaf. Four lettuce cultivars were also used as controls to distinguish heat-tolerant and heat-sensitive cultivars by electrolyte leakage ratio. Among 33 lettuce cultivars were tested in the trial, Lettuce cultivars such as 'Butter lettuce 164' , 'Taiwan white lettuce' , 'Long leaf white lettuce' , 'American romanic red lettuce' , 'Red leaf lettuce' , 'Romanic 157' and 'ERFANO-l' (non-heading type cultivars) and 'stem lettuce V-310' etc. seemed to be more heat-tolerant than 'leaf lettuce V-305' (heat-tolerant control). 'Green leaf lettuce 183' , 'Mayson 73' , 'Mayson 183 'and 'Mayson 165' ,' American lake 366 M.T. 'and 'American lake M.T. 659' were more heat-sensitve than 'Wrinkle-leaf lettuce LS-005' (heat-sensitive control). |
