Abstract

Inadequate supply of pineapple planting materials is one of the major constraints to the expansion of its large scale cultivation in South-West, Nigeria. The effects of types and weight of propagule on the performance of pineapple (Ananas comosus) plantlets was evaluated at the Teaching and Research Farm, Ekiti State University, Ado-Ekiti, Nigeria. Treatments consisted of two propagule types (PT) i.e. Stump, S and Crown, C and three propagule weights (PW); 20-25 g as light weight (LW); 30-35 g as medium weight (MW) and 40-45 g as heavy weight (HW). The experiment was laid out in a randomized complete block design in four replications. The results showed that irrespective of types of planting material used, propagule weights significantly (P<0.05) increased number of pineapple plantlets, length of D-leaf, number of leaves, leaf area and root length. Heavy weight (40-45g) stumps produced the highest number of pineapple plantlets (11)  compared to the least (2) produced by LW stump as well as 3, 6 and 8 produced by LW, MW and HW crowns, respectively. HW Stump produced significantly (P<0.05) higher plantlet biomass weight of 310g compared to other classes of the propagules. It is evident that the use of heavy weight stump could enhance the growth of pineapple plantlets therefore, it is recommended as planting material for the production of plantlets in pineapple cultivation.

Keywords: Pineapple, plantlet, propagule weight, propagation, sprouts.
