“…Hal ini menunjukkan sebaran variasi genetik untuk sifat tinggi dan diameter terdistribusi antar famili cukup besar. Adanya variasi genetik yang tinggi untuk sifat tinggi dan diameter pada tingkat semai juga ditemukan pada jenis binuang (Octomeles sumatrana Mig) (Yudhohartono dan Fambayun, 2012) dan jabon (Anthocephalus cadamba Mig) (Yudhohartono dan Herdiyanti, 2013;Yudhohartono, 2013). Varians galat atau varians individu semai di dalam plot cukup besar nilainya, artinya variasi di antara semai di dalam plot sangat tinggi.…”

ABSTRAKPendugaan parameter genetik untuk sifat tinggi dan diameter nyawai (Ficus variegata Blume) dilakukan terhadap semai yang ditanam di persemaian Balai Besar Penelitian Bioteknologi dan Pemuliaan Tanaman Hutan, Yogyakarta pada umur 8 bulan. Penelitian ini menggunakan bibit dari beberapa pohon induk (famili) asal Pulau Lombok. Rancangan yang digunakan adalah Rancangan Acak Lengkap Berblok (Randomized Complete Block Design) dengan 17 famili sebagai perlakuan, setiap perlakuan terdiri atas 3 ulangan dan tiap ulangan terdiri atas 10 bibit. Analisis varians menunjukkan terdapat perbedaan yang signifikan antar famili untuk sifat tinggi dan diameter. Nilai heritabilitas famili untuk karakter tinggi adalah sebesar 0,98 dan diameter sebesar 0,91 sedangkan korelasi genetik antara sifat tinggi dan diameter adalah sebesar 0,7. Informasi ini sangat penting untuk pemuliaan genetik jenis nyawai di masa mendatang. ABSTRACTGenetic parameters were estimated for height and diameter characteristic of Ficus variegata Blume seedlings planted in the nursery of The Centre for Forest Biotechnology and Tree Improvement, Yogyakarta at 8 months of age. The trial involved seedlings from several mother trees (family) originated from Lombok Island. The trial was arranged in a Randomized Complete Block Design (RCBD) which comprised of 17 families as treatment, 3 replications and each replication comprised 10 seedlings. Analysis of varians showed that height and diameter were significantly different between families. Family heritabilities for height and diameter characteristic were 0.98 and 0.91 respectively, while genetic correlation between the two characteristics were 0.7. This information is very important for future genetic improvement of the species.

Breadfruit is one of the tree species with a wide distribution in the Indonesian archipelago and shows variations in growth morphology, leave, and fruits. Therefore, the breadfruit clonal test plantation was carried out from several origin distributions at vertisol land in Gunungkidul, Yogyakarta, with a spacing of 5 x 5 m. This study aimed to identify the variation in growth and fruit production of 12 breadfruit cultivars at 10 years old. They were collected from Gunungkidul, Kediri, Banyuwangi, Sukabumi, Banten, Bali, Mataram, Lampung, Bone, Malino, Sorong, and Manokwari. The study was conducted by selecting 4 trees from each cultivar that have average growth and replicated five times. The growth characters of breadfruit trees were observed, namely height, stem diameter at breast height, canopy width, and a number of fruits. The observation results showed that there is a significant influence of origin distribution of breadfruit on growth and fruiting performance. The average tree height was 6.1-9.7 m, stem diameter 14.2-22.0 cm, canopy width 3.2-6.1 m, and the number of ripe fruit 3-21 fruit/tree. Breadfruit clones from South Sulawesi (Bone, Malino) and Papua (Sorong, Manokwari) were relatively stable, showing the best performance in all the characters observed. It is indicated that cultivars from South Sulawesi and Papua were adaptable in vertic soil.

As one of the ex situ conservation sites, Purwodadi Botanic Garden (PBG) has Intsia bijuga as its collection with high economic value for its high quality wood. It is categorised as Near Threatened in the IUCN Red List. Its efficacy as herb is due to the presence of its various chemical compounds. The purpose of this study was to characterize the morphology of I. bijuga cultivated in PBG and to reveal its phytochemical compounds, as well as their health benefits. This research was conducted at the PBG in April–May 2020. The plant material was obtained from PBG collection. The plant morphology was characterized by direct observation in the field, while information regarding phytochemical compounds of I. bijuga along with their benefits was obtained by literature review. The data obtained was analyzed descriptively. The results showed that I. bijuga collected by PBG came from Maluku and Java. Both have morphological characteristics that are not very different, i.e., they are trees, they have compound leaves, pale stems with lenticels on their surface, panicle flowers, pod-shaped fruits, and buttress roots. I. bijuga contains polyphenol compounds that have medicinal benefits, such as anti-bacterial, anti-cancer, and anti-viral, hence it has enormous medicinal potential. Due to habitat shrinkage of the species, an effort to have it conserved ex situ is critical.
