Abstract

Fabaceae family has spread-distribution in the tropic region which much potency for human live in the world such as timber, medicine, food, etc. Phenology data give some information which has ecological value, such as character of species and climate change effect to plant activity. Study of leaves senescense of Fabaceae was conducted in Purwodadi Botanic Garden on July – October 2012. Materials of this researches are 79 selected species of Fabaceae. Estimation method of the abundance of leaves senescense was scored 0-4. Air temperature was observed periodically. The conclusions of this research are there four model of leaves senescense and adaptation of Fabaceae (full leaves senescense, leaves senescense and fruiting, evergreen, and less of leaves senescense). More information will be presented in this paper.  Keywords: Fabaceae, dry season, leaves senescense

Abstract

Pterocarpus indicus Wild. merupakan jenis pohon lokal dan termasuk jenis langka yang memiliki beragam potensi antara lain penghasil kayu dan penyerap karbon tinggi dan pola penyebaran anakan belum diketahui. Penelitian ini untuk mengetahui tingkat penyebaran anakan Pterocarpus indicus di sekitar pohon induknya  di Kebun Raya Purwodadi. Hasil penelitian menunjukkan bahwa penyebaran anakan tidak jauh dari pohon induknya dan berada pada kondisi lingkungan dengan kelembaban yang cukup tinggi. Tercatat sebanyak 1392 anakan di sekitar pohon induk sana kembang (Pterocarpus indicus Wild.) pada berbagai arah pengamatan.  Jumlah anakan yang ditemukan banyak terdapat pada tingkat naungan yang tinggi daripada di tempat cahaya terbuka. Pola sebaran anakan angsana dan faktor-faktor yang mempengaruhinya akan dibahas di dalam paper ini. Kata kunci: Anakan, Pterocarpus indicus wild., Kebun Raya Purwodadi

Abstract

Global warming has adverse effects on human life, which can be prevented by planting many trees. Sapindaceae family has various purposes, particularly as fruit producers. However, research on the potential of the Sapindaceae family as a carbon sequester is still lacking. This study aimed to determine the annual increment of biomass and carbon absorption of 22 species from the Sapindaceae family in Purwodadi Botanic Garden. Data were collected using a non-destructive method in the Purwodadi Botanic Garden in July-September 2019. The research tool used in this research included stationery, roll meter, and tally sheet. Biomass was measured with the Kettering equation. The results revealed variations in the value of biomass and the carbon increment of each species. Three species of the Sapindaceae family that have biomass and high carbon increment were Litchi chinensis, Filicium decipiens, and Schleichera oleosa. Keywords: biomass increment, carbon increment, global warming, sapindaceae family

Abstract

Bananas (Musa spp.) are widely cultivated in Indonesia. They are commonly grown in backyards, home gardens, intercropped with short-term crops, and in agroforestry systems. The potential of bananas to sequester carbon has been reported, but information on performance variation among cultivars remains limited. An inventory of biomass and carbon stock (C-stock) estimation was conducted on banana accessions in the Musa germplasm collection of Purwodadi Botanic Garden, Pasuruan. Biomass and C-stock estimations were carried out for 42 individual banana accessions consisting of five wild species and 37 cultivars using a non-destructive allometric equation method for banana. The objectives of this study were to estimate the biomass and C-stock of Indonesian bananas in the Purwodadi germplasm collection, to project time-average above-ground C-stock of banana-based farming systems in Indonesia, and to discuss the role of bananas in landscape rehabilitation. The results showed that biomass and C-stock values varied among accessions. Wild banana species Musa balbisiana had higher biomass and C-stock compared to Musa acuminata. Cultivars containing one or two “B” genomes (ABB and AAB) were more vigorous and contributed higher biomass and C-stock than AAA and AA cultivars. Among the cultivars, the highest C-stock contribution was recorded in Pisang Kepok Bung (average 6.92 kg C/plant), while the lowest was found in Pisang Rayap (average 0.67 kg C/plant). On average, the Indonesian bananas examined contributed approximately 2.26 kg C/plant or 0.98 tonnes C/ha. The total banana growing area increased from 73,539 ha in 2000 to 101,822 ha in 2010 and slightly decreased to 100,600 ha in 2014. These areas contributed an estimated C-stock of 72.28 tonnes (2000), increasing to 100.07 tonnes (2010), followed by a slight decline to 98.97 tonnes in 2014—values based only on recorded cultivation areas. Banana plants—especially when combined with woody tree crops—have potential as key components of agroforestry and mixed farming systems, home gardens, and landscape rehabilitation, contributing to carbon reduction and providing economic benefits for surrounding communities.
