Abstract

本研究於麻豆、大內、善化等地區六年生以上麻豆白柚果園共五處，調查植株一年問枝梢葉片落葉率、春梢萌發位置及生長、著花率及最後結果率等，其結果為：麻豆白柚植株於果實生長期間，其枝梢葉片落葉率極小，於十月間果實採收時僅為10％左右，冬季期間落葉量亦不大，春梢萌嶺前之2月中旬為20%，春梢萌發後4月上旬達90％。顯示春梢萌發期間，枝梢有大量更換葉片之現象，其落葉率因不同生長環境而異。植株之春梢萌發率為86.3%，春梢萌發位置以頂梢為最多，倒數第二梢次之，倒數第三梢最少，分別為84.6％、11.5％及3.9％。春梢結果枝形成率為31.7%，其在結果母枝之著生位置，亦以頂梢為最多，倒數第二梢次之，倒數第三梢最少，分別為86.9％、12.5％及0.6%，且頂梢有較高比率之帶葉花序，植株春梢結果枝之最後結果率為3.4?4.8％。 Survey were conducted at Matou, Tanei And Shanhua in the 6-year-old orchards of Mato Peiyu. The leaf drop pattern, shooting site of the spring flush, inflorescence shoot formation and final fruit-setting were recorded all the year round. Results indicated that less leaf drop was observed during the fruit growing period because leaf drop was accumulated only to 10% in October when the fruits were harvested. Not much of leaf drop was also observed from October to early February of the next year. Before the shooting of spring flush in middle February leaf drop increased to 20%. Since then leaf drop increased greatly to 90% in early April. The data showed that most leaf drop occurred in the growth period of spring flush. Meanwhile, different amount of leaf drop varied in different growth environments. Within a plant, 86.3% of the flushes were shot in the spring and 84.6, 11.5, and 3.9% of them were the terminal, the last second and the last third shoot, respectively. Of the spring flushes, 31.7% were able to produce inflorescence, and most of the inforescence were developed from the terminal shoot, followed by the last second and the last third shoot, they counted for 86.9, 12.5, and 0.6% respectively. More leafy inflorescence Percentage were observed in the terminal shoot. Of the inflorescence shoots, only 3.4-4.8% were found with final fruit settings.
