Abstract

Three macapuno‑bearing dwarf x tall coconut hybrid trees were observed to exhibit some characteristics influenced by the dwarf female parents. Flowering started as early as 39 to 57 months after planting. Intraspadix overlapping of 43 to 100% was also recorded suggesting moderate to high degree of self pollination. Macapuno yield ranged from 0‑50% per bunch. The nuts resem­ble the female parents in form but were generally heavier. They were all classified as type l macapuno. Binomial test showed goodness of fit to 3:1 ratio of normal to macapuno nuts.

Abstract

Bisexual button‑like flowers were found in the dwarf cultivars Albuera, Catigan, Coconino, Lingkuranay, Malayan Red, Malayan Yellow and Tacunan as well as in Baybay Tall in varying frequencies. These hermaphro­dites differed in size, possessed varying number of fully developed anthers that contained pollen with 46.4 ‑84.1% fertility. knong the big hermaphrodites, their distinct characteristics are partly exposed ovary at inflorescence opening and earlier stigmatic receptivity compared with the normal buttons.
