“…immaturesized fruit drop. Some Annonaceae species' flowering and fruiting periods are affected by micro-climate in mother trees (Lestari and Fiqa 2020). Based on Gottsberger (2016), the Anaxagorea plants' group required luminous gaps for growth.…”

“…Air temperature is a climatic factor that greatly affects plant phenological processes. Fruit formation is influenced by various factors, including pollinator effectiveness (Abrol et al 2019;Tanda 2022), endogenous factors (Yuan and Yang 2018;Yan et al 2019;Bu et al 2020), the number and synchronization of male and female flower maturity (Handayani 2016;Oliveira et al 2019;Fathin et al 2021), and environmental factors (Lestari and Fiqa 2020;Zhang et al 2022). Endogenous factors influence, for example, morphological and anatomical chemical construction, such as the content of carbohydrates, water, minerals, nutritional status, and growth hormone.…”

Abstract. Lestari DA, Ningrum LW, Nada FMH, Pradipta NN, Harsono DR. 2023. Flowering and fruiting phenology of Anaxagorea luzonensis A. Gray (Annonaceae). Biodiversitas 24: 784-792. Anaxagorea luzonensis is one of the critical plant collections from the Annonaceae family, with only one specimen in Purwodadi Botanic Garden (PBG). In protecting these plants, it is necessary to know the process of flowering and fruiting through the phenological process. This research is expected to observe plant propagation, physiology, environmental response, and increased reproductive success. The aim of this research is to know the details of flowering and fruiting phenology stages, determine reproductive success, and explain the floral biology of A. luzonensis. Research on the flowering and fruiting phenology of A. luzonensis was carried out from December 2021 – November 2022 in one season at PBG. The method is observative, including changes in color, shape, and size of flowers and fruit in each phenological stage. In addition, the method includes the count of reproductive success and observation of the A. luzonensis flower. This study's results stated that the flowering and fruiting phenology of A. luzonensis experienced a shorter flowering time than fruiting time and a low percentage (<30%) of reproductive success. Flowering stages are divided into five stages, i.e. initiation, flower bud, before bloom, bloom, and anthesis; fruiting stages are divided into three stages, i.e. immature-sized, mature-sized, and ripe fruit, which occurred in period 73-121 ± 85 days. Environmental and genetic factors cause the low value of reproductive success. This research can be useful for the conservation strategy of A. luzonensis, especially for reproduction biology and seed conservation.

In Southeast Asian dipterocarp forests, a general flowering (GF) occurs at the multiannual interval. At this phenomenon, at least 40% of the trees in the stands flower in synchrony, dominated by the flowering of the Dipterocarpaceae family that hypothesized to be caused by changes in climate factors, especially ENSO. This study aimed to determine the pattern of flowering trees in Bukit Barisan Selatan National Park (BBSNP) and to determine a model for predicting flowering patterns associated with climatic factors in 2021-2050. Flowers and fruits were observed every month from February 1998 to September 2020 at Way Canguk Research Station, BBSNP. The climatic factors used were temperature, rainfall, humidity, wind speed, and the ENSO index. We used a generalized linear model to link climatic factors and flowering and model future flowering. The results showed no GF in BBSNP because the highest flower synchronization only reached 37.8%. The climatic factor with the highest coefficient was ENSO, but flowering was mostly influenced by fluctuations in climate factors, not its absolute value. The model estimated that the flowering in 2021 - 2050 will peak to 34.4% in December 2044 and further ensure good forest regeneration. Thus, BBSNP can still be suitable for conservation purposes.

Capparis micracantha is a flowering plant species with a wide range of distributions. It is often used as traditional medicine by local people. This species is often overlooked due to very limited information that reveals about its conservation aspects. This study aims to update the distribution records and predict the potential current distribution of this species. Some new occurrence records were obtained through a direct field survey, plant inventory database, and reliable scientific papers. In order to gain more information about current distribution, Species Distribution Modelling (SDM) was applied to predict the potential current distribution of this species in Indonesia. Two algorithms of machine learning (SVM and GLM) were applied to produce predictive distribution maps. The models were built from occurrence records data and environmental variables (climate and topography). Area Under Curve (AUC) was used to evaluate the model prediction. The AUC value of those models >0.80 means those models have a good performance. The AUC value of those models is stated in SVM (0.86) and GLM (0.824). SVM and GLM have almost similar resulting predictive maps of current distribution. The predictive maps would be useful to give information about the regions in Indonesia that have similar environment characteristics and climate conditions where the species are observably present. This species has also been conserved through ex-situ conservation strategies, but the seedling growth of this species still remains a challenge.
