Eliminating interference by anthocyanin in chlorophyll estimation of sweet potato (Ipomoea batatas L.) leaves.

ABSTRACT:

Background

Spectral reflectance was evaluated for its usefulness as a nondestructive estimation of chlorophyll (Chl) content from three cultivars of sweet potato (Ipomoea batatas L.) with green, yellow, and purple leaves grown in a greenhouse for 22 days. While the green and yellow leaves contain variant amount of photosynthetic pigments without or with little level of anthocyanins, the purple leaves, except large amount of photosynthetic pigments, have high quantity of anthocyanins.

Results

For green and yellow leaves, the reciprocal reflectance (R^-1) and derived indices incorporating near infrared (NIR) reflectance, [(R_λ)^-1 - (R_NIR)^-1] and [(R_NIR/R_λ) - 1], in the green and red edge spectral ranges
