الملخص EN

This study was carried out in date palm research center – Basrah Univ.

during cultivation season 2004.

to study content of some date palm parts(leaflets, fiber, frond midrib, fruit stalks and frond bases) of two cultivars Hillawi and Barhi from lignin and cellulose.

The result explained there is no significant difference between the studied cultivars of their content of lignin and cellulose.

Also the result showed the highest content of lignin appear in frond bases it had (37.63 %) with significant difference of other studied parts, and no significant difference between the leaflets and frond midrib and also no significant difference among leaflets, fiber and fruit stalks.

Also didn’t appear significant difference of interactions.

Also the result showed the highest content of cellulose in fiber it had (48.93 %) without significant difference of frond bases it had (47.28 %), and no significant difference between leaflets and frond midrib, the lowest content of cellulose appear in fruit stalks it had (30.32 %) with significant difference of other studied parts.

To interactions the highest content of cellulose appear in frond bases in Hillawi cultivars it had (52.71 %) without significant difference of fiber of two studied cultivars.

While a lowest content appear in fruit stalks in Barhi cultivars it had (27.32 %).
