Abstract

Wild-type raspberries are part of forest succession and could be cultivated owing to their benefits and economic value. The development of cultivated plants depends on the quality of the genetic material used for propagation. Phenological studies are the first step in assessing the quality of genetic material and in determining the overall developmental process. This research aims to study the development and morphology of flowers, fruits, and seeds. This research was conducted at Cibodas Botanical Garden from September 2022 to March 2023. The experiment used wild-type raspberry species as a factor in a randomized complete block design. The results showed differences in the developmental phases and morphology of flowers, fruits, and seeds, as well as in stigma receptivity, among R. fraxinifolius, R. rosifolius, and R. ellipticus. Flowers take 11–15 days from initiation to anthesis, and the receptivity of the stigmas of the three species reaches a peak one day after anthesis in the morning. The fruit is ripe at 39–46 days after anthesis with a different color.
