GLORIA, NESTOR W., University of the Philippines at Los Banos. August, 1982, Growth and Fiber Morphology of Abaca (Musa textilis Nee) Ratoons as Influenced by Plant Density and N Level. Major Professor: Prof. Ernesta G. Quintana
An old abaca plantation was subjected to butcher harvest as a rejuvenation process. The subsequent ratoons were evaluated in terms of growth and fiber dimensions as influenced by plant density and nitrogen level. Replants served as checks in determining the merits of ratooning.
Ratoons emerged approximately 13 days earlier than replants. Ratoons were not severely damaged by pests regardless of density and N levels of application. Slight damage caused by slug caterpillar and corm " weevil was observed,
Generally, ratoons had more rapid vegetative growth than replants regardless of plant density and N level, although it appeared that the application of 100 kg N/ha favored height and girth increment after a period of 12 months. Unlimited ratoons exhibited better performance over ratoons at controlled density. At advanced stages, however, a reduction in girth showing characteristics of "taguiltils" was observed in unlimited ratoons.
In other gross morphological characteristics like petiole length, leaf blade length and width, ratoons at any density manifested superior performance over the replants, Furthermore, ratoons also had Significantly higher fresh and dry matter weight of stalk and leaves than the replants.
Leaf N content significantly increased with increased N application during the 6th month but not after 12 months. Plant density did not affect leaf N content.
Generally, N application did not significantly affect fiber cellular dimensions, however, the fiber dimensions of ratoons at any density were significantly bigger than those of replants.
