 note = {シークヮーシャー葉澱粉の経時および季節的変化を調べた。単離した澱粉, さらに澱粉から分離したアミロースおよびアミロペクチンのヨウ素呈色液は, それぞれの特性を示した。澱粉は日中多く, 夜間減少すること, 一方, アミロペクチン/アミロース比は日中低く, 夜間高い値を示すことが解った。澱粉は10月初旬に最も多く3.51%(対乾燥葉)で, 11月下旬急激に減少(0.69%)し, 1月下旬から再び増大し2月初旬には1.74%であった。澱粉のヨウ素呈色液の極大吸収は10月に最も低く(563nm), その後徐々に高波長側へ移行し, 2月には573nmであった。一方, アミロペクチン/アミロース比は10月に最も高く(4.17), その後徐々に減少し, 2月には2.97であった。, Seasonal and daylong variation of starch and amylopectin/amylose ratio in the leaves of C. depressa HAYATA were investigated. The results obtained were as follows; 1 Starch was prepared from the leaves of C. depressa by the yield of 0.23% of the fresh tissues. Amylose and amylopectin were prepared from 1.00g of the starch by the yield of 33% and 67%, respectively. 2 The iodine coloration spectrum of starch, amylose and amylopectin showed the characteristics of their own. The content of starch in the leaves of C. depressa showed high value in the day time, however it showed low value in the night time. The amylopectin/amylose ratio of C. depressa showed high value in the night time but showed low value in the day time. Quantitative determinations of starch in the leaves of C. depressa were carried out throughout five months. The content of starch showed the maximum value in October, and the value rapidly decreased from November till January, and then increased., 紀要論文},
