Abstract. Putra RE, Wibisana G, Kinasih I, Raffiudin R, Soesilohadi RCH, Purnobasuki H. 2023. Pollination biology of yellow passion fruit (Passiflora edulis forma flavicarpa) at typical Indonesian small-scale farming. Biodiversitas 24: 2179-2188. Yellow has been considered one the potential local fruits targeted as export commodity Indonesia. However, this production level is relatively unstabl...

Multiple interacting factors drive recent declines in wild and managed bees, threatening their pollination services. Widespread and intensive monitoring could lead to more effective management of wild and managed bees. However, tracking their dynamic populations is costly. We tested the effectiveness of an inexpensive, noninvasive and passive acoustic survey technique for monitoring bumble bee ...

The Himalayan endemic alpine genus Roscoea, like other members of ginger family, exhibits the combination of floral traits that would fit pollination by long distant foragers such as bees, birds or flies. We studied the pollination biology of Roscoea alpina, observed potential floral visitors and determined their foraging behaviour, visitation frequency and pollination efficiency, to seek evide...

For several plant species, brood size results from the abortion of ovules and seeds. However, these processes have rarely been studied together in wild plants. In some of the leguminous species studied, seed abortion has been found to depend on pollen quality and on the position of the ovule or fruit. The direct consequence for the mother plant is that fruit costs increase as the seed:ovule rat...

Understanding the natural mating behavior (selfor cross-pollination) in watermelon is important to the design of a suitable breeding strategy. The objective of this study was to measure the rate of selfand cross-pollination in watermelon [Citrullus lanatus (Thunb.) Matsum. & Nakai] using the dominant gene Sp (Spotted leaves and fruit) as a marker. The experiment consisted of two studies and was...

a number of grapevine cultivars have female flowers and for better fruit set, they need pollinizer. single planting of these cultivars leads to severe decrease in fruit set. this research was carried out to investigate the effect of cross pollination with four grape cultivars (askari, rish baba, bidane sefid and tabarze sefid) on fruit set, bunch weight, berry per cluster, average weight of 20 ...

In red clover seed production, low yield is limiting the commercial exploitation of tetraploid clover. To explore if pollination factor for in clover, we investigated pollinator behaviour and plant reproductive success diploid (2x) cultivar ‘Rajah' (4x) ‘Amos' using honey bee hand approaches. We measured set at flower head level with increasing visitation rate bees (one bee, two open pollinatio...

Abstract Key message Paternity analyses show that effective pollination of ash ( Fraxinus excelsior L.) in a seed orchard and floodplain forest affected by dieback is more likely to be facilitated healthier males. Thereby, natural selection can have positive effect on the health future generations. Context Ongoing increasing fragmentation populations may result reduced pollen flow, which reduce...

The reproductive biology encompassing phenology, floral biology, pollination and breeding systems, of Butea monosperma, a beautiful tree of the Indian subcontinent, was investigated in a protected dry, deciduous forest located in New Delhi. Phenological studies indicated that although the species shows a regular flowering season, all trees do not flower every year. Flowers are typically papilio...

Autonomous self-pollination may be considered as a mechanism enhancing plant reproductive success when plant access to pollen sources may limit seed production. We have studied the relationship between geographical patterns of variation in pollinator service to Helleborus foetidus and self-pollination ability in three widely spaced regions in the Iberian Peninsula. As could be expected from its...
