Neue Wirkungen des Wachstumsregulators Ancymidol bei Karotten

New effects of the growth regulator Ancymidol in carrot plants . Ancymidol, generally known as growth retardant substance for ornamental plants, reduced length and weight of carrot leaves. Weight of roots, however, was either unchanged or was increased. So the leaf/root‐ratio was considerably narrowed. Pure protein content of leaves and roots increased, in the case of roots also the yield of pure protein. A regulation of plant growth and plant metabolism in this direction could be of importance also for other root crops.
