ABSTRACT:
Plant growth and suppression regulators of the N-(2-substituted-4-pyridyl)urea and thiourea type are provided, which exhibit excellent cytokinin-like activities and are thus useful for regulating plant growth in various fashions, such as acceleration of growth when used in flowering or fruiting at a controlled time when used in small amounts, and controlling compositions such as sugar, alkaloids, etc. of plants, or suppression of plant growth when used in an amount higher than optimal for growth acceleration, etc.
