Abstract
EFFECT OF SEED SIZE ON GERMINATION AND SEEDLING GROWTH OF SPECIES STEMONA TUBEROSA LOUR.
Experimental results of the effect of seed size on germination and seedling growth species of Stemona tuberosa Lour. showed that, larger seeds germinate earlier, in a shorter time, but the germination rate is lower than that of smaller seeds. Seedlings from larger seeds had higher height, root diameter, number of stems, and number of leaves than seedlings from smaller seeds, nevertheless the difference was only significant when comparing large and medium seeds with small seeds, and not significant between large seed and medium seeds (P=95%). The highest percentage of nursery seedlings was in medium seeds (57,33%), compared to 56,67% in large seeds and 46,33% in small seeds. Therefore, seeds with a size of ≥ 1.5 x 0.3 cm (medium seeds) were selected as the basis for establishing seed standards species of Stemona tuberosa Lour.
