摘要

Pure protein, chlorophyll, carotene, and carbohydrates of Daucus carota throughout the vegetative period of first year as influenced by growth regulators (CCC, GA and BA).1) Carrot plants were treated for 9 weeks with gibberellic acid (GA3), benzyladenine (BA) and chlorcholinechloride (CCC). 2) Yield of carrot roots (g/plant) was reduced by GA, and changed insignificantly by CCC and BA. Leaf yield was increased with GA and BA, and decreased with CCC. 3) The quantity of pure protein in carrot roots (mg/plant) increased with CCC and decreased with GA and BA. Opposite results were obtained for leaves. 4) The quantity of hydrolysable carbohydrates (g/plant) in roots decreased with GA, BA and CCC. In leaves GA and BA increased the yield of carbohydrates whereas CCC decreased it. 5) The quantity of carotene (mg/plant) in roots decreased strongly with GA and negligibly with BA. CCC increased the yield of carotene. 6) The quantity of chlorophyll (mg/plant) increased with GA and decreased with CCC. BA increased chlorophyll during the first half phase of the vegetative period and decreased in the other half phase. 7) Following relations were calculated for the duration of the vegetative period: a) hydrolysable carbohydrates to pure protein of leaves and roots. b) carotene (in the roots) to pure protein (in the leaves) c) Carotene (in the roots) to carbohydrates (in the roots) d) carbohydrates to chlorophyll in the leaves, furthermore was calculated e) the storing power of the living system of leaves for carbohydrates in the roots. 8) The time curves for daily synthesis capacity of system of leaves or their storing capacity for products in the roots show that protein, chlorophyll and carotene of leaves behave as components of the system while carbohydrates (as expected) belog to the product. Contrary to that the daily storing capacity of the system of leaves shows that protein, carotene and carbohydrates in the roots belong to the product. Thus the root proves to be a genuine storage organ in which the major quantities of protein and carotene are not involved in the metabolic processes but can be regarded as stored or end products. .
