Notes	Seasonal differences of contents of free amino acids and sugars of the lower-parts of rice stems whose leaf blades were cut off at six different stages of growth of rice plants were studied by paper chromatography. Amino acids found always in both of treated and non-treated rice culms were as follows: aspartic acid, glutamic acid, glycine (or asparagine), alanine, threonine (or glutamine), α-amino butylic acid, valine, leucine, serine, tyrosine and cystic acid. No qualitative effects on the members of amino acids were found by the reduction of the leaf blades. Sugars found always in the above mentioned culms were sucrose, glucose and fructose. It seems likely that there exist some correlations between the decrease of sucrose contents of the stem bases of rice plants and the increase of severity of stem rot of rice plants whose leaf blades were cut off at different stages of the plant growth.
Notes	水稲の穂孕期から出穂期にかけて稲葉剪除を行えば,稲小粒菌核病の被害度が非常に増大する.その原因を生化学面より追究する目的で著者は第1 第2報に於て,時期別に稲葉剪除した水稲茎基部の炭水化物及び各態窒素含量について分析を行い,穂孕期及び出穂期の稲葉剪除で,炭水化物含量は急減するのに対して,窒素含量では剪除による影響はあまり見られず, 唯可溶性窒素が稍〃増加する傾向のあることを認め,従来から云われている被害度の大きくなる状態に置かれた水稲の茎基部では,炭水化物は減少し,C/N 率は低下することが見られた.本研究は,前報告と同様に,時期別に稲葉剪除を行い,それによる水稲茎基部の遊離アミノ酸及び遊離糖含量の変動を時期別にペーパークロマトグラフ法で検索し,稲小粒菌核病の被害度と関連があるかどうかを見たものである．
