| Abstract: | On exposure to light the outer parenchyma layers of mature potatobecame green as amyloplasts are converted to chloroamyloplasts.This tissue was sampled during greening, and analysed for nuclearand plastid DNA content. There was an increase in the proportionof plastid DNA in total DNA from 15% in white tuber tissue to22% in greened tissue, while the nuclear ploidy distributionand average nuclear ploidy was similar in both. Key words: Solatium tuberosum, greening, amyloplast |
