中文摘要 | 麻豆白柚植株之落葉習性,其老化的葉片,先由葉身脫落,2∼5日後葉柄再行掉落,落葉全日進行,而葉身日間掉落率為71.9﹪,且主要分佈在午後高溫期。植株每年於2∼3月間抽生春梢及開花期間,結果母枝的葉片有大量掉落,當春梢萌發初期落葉量較少,其後落葉量隨春梢之抽生而急速增加,且日落葉量第一次高峰期出現於抽梢後期,第二次高峰期則出現於盛花期。麻豆白柚葉片壽命最長可達24個月,短者壽命僅1個月,葉片壽命長短以11∼12個月為最多,如春梢延後萌發則壽命為11∼13個月,其次壽命長短則為21∼24個月。 |
英文摘要 | The results indicated that leaf-dropping occurred in the aging leaves and lamina dropped first in the daytime which counted for 71.9% and mainly distributed in afternoon in Mato Peiyu (Citrus grandis Osbeck). The petiole dropped was found in the next few days both in the day and night times. Large portion of the lamina on the mother fruiting shoot dropped between February and March when trees were flushing and flowering. Less portion of leaf dropping was observed in the early flushing stage and then increaced with time. First peak of the leaves dropped / day occurred in the late flushing stage, and the second peak appeared in the full flowering stage. Leaves of the Mato Peiyu trees can remain on the shoots as long as 24 months and longevity of leaf distributed in every month. The longevity of leaf mainly remained on the 11th-12th month after the flushing , the mainly age in 11-13th month when the spring flush delayed, and the next longevity of leaf in the 21-24th month. |
