THE PHYSIOLOGY OF HOST–PARASITE RELATIONS: IVA. THE EFFECT OF MALEIC HYDRAZIDE ON THE CARBOHYDRATE, NITROGEN, AND FREE AMINO ACID CONTENT OF THE FIRST LEAF OF KHAPLI WHEAT

摘要: Khapli wheat was grown in sand culture 1-qt. crocks. Daily applications of maleic hydrazide (10 mg. per crock) were started about 10 days after sowing. After 5 to 12 or 15 treatment, samples taken for analysis. Maleic inhibited growth and caused increases the dry weight, total soluble matter, sucrose, free amino compounds, particularly glutamine glutamate, first leaves. The treated leaves also rich starch which does not normally occur leaf.
