Na te hekenga o te ihirangi methoxyl, ka piki te tohu o te reera, ka heke te wairewa wai, ka heke ano te mahi o te mata. Ko te hua ano nga ahuatanga o te kaha o te matotoru, te tote tote, te paura pungarehu iti, te pumau o te pH, te pupuri i te wai, te pumau o te rahi, te hanga kiriata pai, me te whānuitanga o te aukati, te whakamararatanga me te whakakotahitanga.
