摘要

以黑色美式PE圓孔穴盤培育之甜椒苗易產生盤根造成老化，本試驗以十字漏空穴盤培育`銘星’甜椒苗，調查不同苗齡苗之生育性狀、根活性、相對呼吸量和乙烯生成量及植株之田間產量，據以評估其改善穴盤苗老化之效果及培育優良苗株之苗齡。種苗各性狀隨苗齡提高而增加，始花日數則相反。漏空處理之穴盤苗根長顯著較短，側根較早發生，但八週苗齡植株之根部老化現象較為嚴重。相對呼吸量、乙烯生成量及根活性皆隨苗齡提高而增加。同苗齡中，圓孔之穴盤苗相對呼吸量較低，乙烯生成量則較高；漏空處理者之相對呼吸量較高，乙烯生成量則顯著較低。漏空處理者之早期產量及總產量顯著較高，單株果數以六週苗齡者之3~10個為最多。圓孔者單株果數平均在4~6個，以八週苗產量最好，但不及漏空處理者且早期產量較低。

Root circling of sweet pepper seedling was problem in round cell of 128-cell PE plug tray. The height of seedling increased and the initiated date of flowering was short during the seedling growth from the fourth to the eighth week. The side root was increased when the seedling grew in the cross openings of the sidewall of cell. However, the activity of the eighth-week-old sweet pepper root was decrease. At the same age of seedling, the amount of ethylene was higher from the round cell than that from the opening cell. The respiration rate was reversed. The survival rate at the fourth-week-old was the lowest compared to that at other ages. The early yield and total yield of the seedling in the opening cell were higher than that in un-opening tray. The six-week-old seedling grown in opening plug tray had the highest fruit number, however that in un-opening plug tray was eight-week-old.
