Contents of total nitrogen, total amino acids, caffeine, and tannin decreased slowly during the growth of the first crop. The neutral detergent fiber contents in shoots was about 19% at the timing of best quality, then increased rapidly. The moisture contents was under <80% in immature shoots, about 80% a few days before the timing of best quality time, and subsequently decreased to 75%.}, pages = {19--27}, title = {摘採適期前後におけるチャ品種 'やぶきた', 'りょうふう', 'ふうしゅん' の一番茶新芽の化学成分含有量の変動}, volume = {15}, year = {2016}, yomi = {イケダ, ナミコ and ミズノ, ナオミ and タナカ, タクヤ and アライ, シンイチロウ and マツノブ, ケンシン} }
