ABSTRACT
Six varieties of Ficus deltoidea Jack (Moraceae) showed
leaf morphological variations through quantitative measurement on different
plant parts. There were significant differences among six varieties studied by
plant parts. The varieties studied include var. deltoidea Corner,
var. angustifolia (Miq.) Corner, var. trengganuensis Corner,
var. bilobata Corner, var. intermedia Corner, and var. kunstleri (King) Corner. The upper,
middle and lower plant parts showed morphological variations in terms of leaf
length, leaf width, leaf area and petiole length. Qualitative parameters also
showed trends in morphological variations in terms of leaf shape, leaf base,
leaf apex and leaf attachment. However, some qualitative parameters were not
the recommended parameters to differentiate among varieties. On the other hand,
leaf heterophylly has occurred in F.
deltoidea because foliage of the young plant was different
from the mature plant. Leaf heterophylly was observed in leaf shape and leaf
apex parameters, whereby leaves from the lower plant parts were different from the
upper and middle parts. The heterophylly in leaf shape was detected in
varieties angustifolia, bilobata, intermedia and trengganuensis, whilst six varieties
of F. deltoidea showed leaf apex
heterophylly.

ABSTRAK
Enam varieti Ficus deltoidea Jack (Moraceae) telah
menunjukkan pelbagai variasi morfologi daun melalui ukuran kuantitatif pada
bahagian pokok yang berlainan. Terdapat perbezaan yang signifikan
di antara enam varieti yang dikaji berdasarkan bahagian pokok yang berbeza. Varieti yang yang dikaji termasuklah var. deltoidea Corner,
var. angustifolia (Miq.) Corner, var. trengganuensis Corner,
var. bilobata Corner, var. intermedia Corner, dan var. kunstleri (King)
Corner. Bahagian atas, tengah dan bawah pokok
menunjukkan pelbagai variasi morfologi dari segi panjang daun, lebar daun, luas
permukaan daun dan panjang petiol. Parameter
kualitatif juga menunjukkan tren dalam variasi morfologi dari segi bentuk daun,
bentuk dasar daun, puncak daun dan lampiran daun. Walau
bagaimanapun, beberapa parameter kualitatif tidak disyorkan untuk membezakan
varieti-varieti berkenaan. Sebaliknya, terdapat heterofili daun pada F. deltoidea kerana dedaun tumbuhan
muda berbeza dari pokok yang matang. Heterofili daun
diperhatikan pada bentuk daun dan parameter puncak daun, di mana daun dari
bahagian pokok yang lebih bawah adalah berbeza dari bahagian-bahagian atas dan
tengah. Heterofili dalam bentuk daun dikesan dalam
varieti angustifolia, bilobata, intermedia dan trengganuensis, manakala enam varieti F.
deltoidea menunjukkan heterofili pada puncak daun.
