Abstract |
The mechanism of dusky reddish-brown "kaki" color development of morning glory, Ipomoea nil cv. Danjuro, was studied. Three major known anthocyanins were isolated as glucosylated pelargonidin derivatives. Measurement of the vacuolar pH with proton-selective microelectrodes revealed the vacuolar pH of the colored cell of open flowers to be 6.8, while that of buds was 5.8. Mixing of the three anthocyanins according to the composition ratio in petals at pH 6.8 allowed the identical color to that of petals to be reproduced. The typical "kaki" color development was mostly caused by 5-OH free acylated anthocyanins, which have two lambdamax around 435 and 535 nm in the visible region. |
