Influence of Environmental Factors on Smallflower Morningglory (Jacquemontia tamnifolia) Germination and Growth
Keyword(s):
The optimum pH for germination of smallflower morningglory (Jacquemontia tamnifolia(L.) Griseb. # IAQTA] seed was 8.0. A scarification time of 25 to 60 s using a drum scarifier with medium grit provided the best germination, and the optimum temperature for germination was 35 to 40C. However, the optimum temperature for growth was 25 to 35C, with reductions in growth occurring above or below this range. Emergence after 14 days was 81 and 49% at planting depths of 1.5 and 10 cm, respectively. Shade levels of 30 to 92% reduced smallflower morningglory growth by 38 to 87% compared to plants grown in full sunlight.
