Lignin and Cellulose content in some parts of date palm Phoenix dactlifera L. Cultivars Hillawi and Barhi

Abstract

This study was carried out in date palm research center – Basrah Univ. duringcultivation season 2004. to study content of some date palm parts(leaflets, fiber, frondmidrib, fruit stalks and frond bases) of two cultivars Hillawi and Barhi from ligninand cellulose.The result explained there is no significant difference between the studied cultivars oftheir content of lignin and cellulose. Also the result showed the highest content oflignin appear in frond bases it had (37.63%) with significant difference of otherstudied parts, and no significant difference between the leaflets and frond midrib andalso 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 significantdifference between leaflets and frond midrib, the lowest content of cellulose appearin 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 Hillawicultivars it had (52.71%) without significant difference of fiber of two studiedcultivars. While a lowest content appear in fruit stalks in Barhi cultivars it had(27.32%)
