Notes
Seasonal changes of carbohydrate and nitrogen contents of the lower parts of rice culms whose leaf blades were cut of at six different stages (stem elongation, head initiation, 10 days before earing, earing, 10 days after earing, and milk stages) were studied. Contents of total nitrogen and protein nitrogen were scarcely affected by the leaf blade excisions; but soluble nitrogen somewhat increased by the cuttings treated at 10 days before earing and earing stages. On the contrary contents of carbohydrate decreased by the cuttings treated at 10 days before earing and earing. Similar tendencies were seen on the C/N ratio. Contents of carbohydrate and C/N ratio of all treated and non ?treated rice plants decreased rapidly after milk stages.
穂孕期から出穂期に亘つて稲葉の剪除を行えば,稲小粒菌核病の被害度が著しく増大することはすでに報告した所である.このような被害度増大の原因を水稲茎基部の生化学面より追究する予備実験として,第1報に於ては健全水稲について,伸長生長期より乳熟期までの体内成分（炭水化物及び窒素), 酵素（catalase, polyphenol oxidase, peroxidase, amylase)活性,及び呼吸作用について測定を行った. これらの中,炭水化物の含量は生育時期の経過と共に増大するのに対して,窒素は逆に時期の経過と共に減少する傾向が認められた.本報に於ては,伸長生長期より黄熟期に至る迄時期別に稲葉剪除を行い,これらの乗除が茎基部の炭水化物及び窒素含量に如何なる変化をもたらし,又それらが時期別に如何なる変化を来すかを見たものである.
