摘要: 本試驗採用"台中亞蔬四號"、"農友301"及"農友202"番茄品種為材料,探 討苗齡(4週、6週、8週或10 週)對三品種苗株生育與早期產量的影響。三 個育苗期之試驗結果顯示,三品種苗株之園藝性狀均以8週苗最大,4週苗 最小。苗株之株高及葉面積以11月17日定植苗株之園藝性狀均以8 週苗最 大, 4週苗最小。苗株之株高及葉面積以11月17日定植者最大,節間數與 葉數則以9月22日定植者最多。12月2日定植苗株之園藝性狀均顯著小於其 他二育苗期。 11月17日定植後苗株之根系比活性均呈增加趨勢,而於12 月2 日定植 4週苗之根系比活性較其它苗齡苗者大。於11月17日及12月2 日定植之4 週苗有最佳的回復力。品種及苗齡對於1993年12月4日定植 及1994年1月15日定植苗株之平均始花日數均無影響。品種對前述二期定 植之第一花序著生節位亦無影響,然苗齡對1993年12月4日定植者呈二次 效應,對1994年1月15日定植者則呈一次效應。1993年12月4日定植植株之 早期產量以"農友 202"最高, 1994年1月15日定植者則以"台中亞蔬四號" 最高,二期作均以10 週苗的早期產量最高。
Greenhouse and field experiments were conducted to study the influence of seedling ages (4、6、8 and/or 10 weeks) on growth and early yield of fresh-market tomato. Older seedlings in plug tray (20ml/plug) showed bigger plant size at transplanting in all three cultivars. The root specific activity of seedlings transplanted on November 17, 1993 increased after transplanting, but the root specific activity of 4 week old seedlings transpl- anted on December 2, 1993 were higher than other seedling. Four old seedlings transplanted on November 17, 1993 and December 2, 1993 had the best recovery from transplanting. There was no significanct difference on days to flowering of seedlings transplanted on December 4, 1993 and January 15, 1994 either among cultivars or among seedling ages. The first node of inflorescence(FNI) were not different among cultivars. There was a quardratic response of age upon FNI for seedlings transplanted on December 4, 1993 but the response was linear for seedlings transplanted on January 15, 1994."Known You 202" had the highest early yield for December 4, 1993 transplanting had the highest early yield for January 15, 1994 transplanting. Ten week old se- edlings had the highest early yield for both experiments transpl- anted on December 4, 1993 and on January 15, 1994. The diffreence between three planting seasons were also exam- ized. Seedlings transplanted on September 22, 1993 had the high- est plant height and leaf area. However, seedlings transplanted on November 17, 1993 had the highest number of nodes and leaves. The plant size of seedlings transplanted on December 2, 1993 were significantly smaller than seedlings transplanted in Sep- tember and November .
