3. Results3.1. Morphology Indicator for Capsule MaturityThree days post-bloom, this study’s P. labukensis flower samples were manually pollinated to procure reliable and adequate seed sources for the seed germination stage.Capsule development in length and diameter after 15 days of hand pollination increased.Subsequently, 7–10 days post-pollination, the diameter of the capsules rose from 0.5 to0.8 ± 0.3 cm. In the following 15 days, the diameter and length of the capsules reached1.15 ± 0.53 cm and 10 ± 0.5 cm, which remained constant until maturation. On average, thecapsules were 4–10 cm on the longest axis and 0.8–1 cm long on the widest axis (Figure 1)
