Abstract

White jasmine (Jasminum sambac (L.) Aiton) is one of the ornamental plants whose flowers are widely used. However, information regarding flower development, especially the flowering phenology of this plant, is still limited. This study aims to obtain information on the flowering phenology of melati putih and the morphological characterization of the flowers. Flowering phenology data was analyzed qualitatively, while flower morphology character data was analyzed quantitatively. The results show that the flowering phenology of melati putih takes place in an average of 26 days with environmental factors being light intensity 337.00-2639.00 lux, air temperature 27-34oC, humidity 61-82%, and rainfall 0.0–9.6 mm. Air temperature and humidity influence the process of bud emergence and the length of time for large buds to develop towards anthesis. The morphological characters of the flower is inflorescentia cymosa, pleiochasial type with trumpet-shaped, white color, and classified as a complete flower. Small flowers have an average flower length of 26 mm and an average diameter of 31 mm. There are 8-10 petals (calyx) with an average length of 8 mm and diameter is 6 mm. The crown (corolla) is composed of 7-10. Each flower has two stamens and a pistil.

Abstract

Butterfly pea (Clitoria ternatea L.) is one of the plants that has potential as a medicinal plant. This potential is based on the many compounds that can be useful in the pharmacological field. Information on flowering phenology and morphological characterization of Butterfly pea flowers is the focus of this study. This study aims to examine each phase that occurs during the stages of flower development associated with environmental factors, and identify the morphological characteristics of butterfly pea flowers. This research was conducted at Ternate Street, The Hok, Jambi Province, in July-September 2024. The data generated are descriptive, qualitative, and quantitative. The results showed that butterfly pea flowers have a flowering stage that lasts for 11-14 days, with environmental factors that tend to be unstable. Morphological characterization of butterfly pea shows that flowers include papilionaceous, namely flowers with irregular corolla arrangement with a total of five strands and including hermaphroditus flowers with zygomorphus type and there are two bractea organs.
