Cells were elicited in cell suspension and seedlings by root uptake of products. With salicylic acid and phosphorous acid, polyphenol oxidases activities were multiplied by 1.6 to 3 in yac ǎnd 1.2 to 4 in TMS4(2)1425 according to the organs. They were 3 and 4 times higher in cells of TMS4(2)1425 treated respectively with phosphorous acid and salicylic acid, and 3 times in leaves of yac ǎnd TMS4(2)1425 elicited by acid phosphorous. Amount of phenols increased from 25 to 110%. The highest accumulations were recorded in cells treated with salicylic acid (67.8% [TMS4(2)1425]; 110% (yac)̌) and leaves treated with Sumi 8 (32% [TMS4(2)1425]; 68.9% (yac)̌). With phosphorous acid, the increase of these compounds was greater than 50% in cells. It was 21% [TMS4(2)1425] and 38% (yac)̌ in leaves. Each elicitor would have a specific action in cassava cultivars.Traduction de : En| Type de document | Site actuel | Cote | URL | Statut | |

The aim of this study was to evaluate the activities of immobilize and cytoplasmic polyphenol oxidases,
and quantify phenols in cells and seedlings of cassava cultivars yac ǎnd TMS4(2)1425 elicited by
salicylic acid, phosphorous acid and Sumi 8 (diniconazole). Cells were elicited in cell suspension and
seedlings by root uptake of products. With salicylic acid and phosphorous acid, polyphenol oxidases
activities were multiplied by 1.6 to 3 in yac ǎnd 1.2 to 4 in TMS4(2)1425 according to the organs. They
were 3 and 4 times higher in cells of TMS4(2)1425 treated respectively with phosphorous acid and
salicylic acid, and 3 times in leaves of yac ǎnd TMS4(2)1425 elicited by acid phosphorous. Amount of
phenols increased from 25 to 110%. The highest accumulations were recorded in cells treated with
salicylic acid (67.8% [TMS4(2)1425]; 110% (yac)̌) and leaves treated with Sumi 8 (32% [TMS4(2)1425];
68.9% (yac)̌). With phosphorous acid, the increase of these compounds was greater than 50% in cells.
It was 21% [TMS4(2)1425] and 38% (yac)̌ in leaves. Each elicitor would have a specific action in
cassava cultivars.
