“…Plants whose height at the time of flooding was lower than in stagnant water would experience death due to all parts of the plant being submerged. These findings were also similar to Yuniarti et al [16], who observed planting failure due to the ability of seedlings adapting drought and inundation. Tata et al [17] also said that initiaves and efforts to encourage plant growth on degraded peatlands in Indonesia can be successful if plant seeds can survive in flood.…”

Peatland plays an important role as the storage of carbon stocks both in the soil layer and biomass. The value of carbon stocks in peatlands is strongly influenced by the peatland’s quality and potential to produce carbon emissions if the natural conditions are disturbed. Revegetation can improve the quality and land cover compared to natural succession. The success of revegetation can be seen from the survival rate and growth performance of planted species. The purpose of this preliminary study was to see the survival rate and growth of four species of revegetation plants in the burnt peatland area located in Pedamaran, Ogan Komering Ilir, South Sumatra in 2017 and 2021. This study was carried out using quantitative descriptive methods. Results show that the growth performance of four endemic revegetation species was different, reflected by the diameter of breast height (dbh), height, and survival rate. Based on data, pulai (Alstonia pneumatophore) show the best growth performance compared to tembesu (Fragraea fragrans), jelutung (Dyera polyphylla), and balangeran (Shorea balangeran). Pulai showed the highest survival rate (98.61%), with an average dbh growth of 8.31 mm and 75.60 cm in height. Furthermore, all data obtained in this study can be used as basic data for revegetation development to increase growth and survival rate, enhance carbon stocks, and other efforts in climate change mitigation and adaptation.

“…Biji yang telah matang akan memiliki cadangan makanan yang cukup untuk pertumbuhan embrio. Skarifikasi dengan air panas memberikan pengaruh nyata terhadap persentase perkecambahan, karena perendaman biji dalam air panas dapat melunakkan kulit biji yang keras sehingga dapat memudahkan proses imbibisi dan mempercepat proses perkecambahan (Suhartati & Alfaizin, 2017). Melalui proses skarifikasi tersebut dapat menghasilkan biji yang bersifat permeabel.…”

Timoho (Kleinhovia hospita) wood is one of the raw materials for keris sheath that having high aesthetic and economic values. Due to exploitation of keris raw material that outmatches its planting activities, this type of tree is already hard to find in the Special Region of Yogyakarta, so this research aims to determine the generative propagation techniques carried out in the nursery of Center for Forest Biotechnology and Tree Improvement. Genetic material in the form of seeds in this study came from the parent trees grown in Bulaksumur region and Purwobinangun region, Yogyakarta. The methods that will be used are sampling, seed extraction, seed scarification in hot water for 24 hours, germination using wet tissue as media in petri dish, and planted in polybags. The result showed that viability of seeds from Bulaksumur region was 80% while that from Purwobinangun region was 68%. Observation and measurement of stem length and number of leaves every 2 weeks for 42 daysshowed that the number of timoho seed leaves from Purwobinangun hada higher number of leaves and a longer stem length, which is 19,11 ± 2,66 leaf blade and 11,54 ± 2,77 cm than the number of leaves and stem length from Bulaksumur, which is 0,59 ± 1,07 leaf blade and 7,59 ± 1,17 cm. Based on thisresearch, it was concluded that although the viability of seeds from Bulaksumur was higher, the possibility of inbreeding from it broodstock caused the growth of seeds from Bulaksumur not as good as the growth of seeds from Purwobinangun

“…Benih kayu kuku termasuk dalam kategori benih ortodoks yang dapat disimpan pada kadar air relatif rendah dan mempunyai kulit benih yang keras, sehingga menyebabkan benih sulit untuk berkecambah (dormansi eksogenius) (Suhartati dan Alfaizin, 2017). Karakter benih tersebut membuat benih kayu kuku bisa disimpan dalam waktu yang lama dan bijinya yang bersifat dormansi tersebut menyebabkan biji sulit berkecambah sehingga memerlukan skarifikasi untuk mempercepat perkecambahannya (Suhartatiet al,2015).…”

PENGARUH SKARIFIKASI DAN LAMA PENYIMPANAN BENIH TERHADAP VIABILITAS BENIH KAYU KUKU (Pericopsis mooniana[Thw]Thw.)

Abstrak: Kayu kuku (Pericopsis mooniana [Thw] Thw.) merupakan jenis dari famili Fabaceae. Kayu kuku dilaporkan termasuk dalam jenis kayu lokal sulawesi yang saat ini masuk kategori terancam punah. Penelitian ini bertujuan untuk mengetahui viabilitas benih kayu yang dipengaruhi pengikiran dan lama penyimpanan. Penelitian ini dilaksanakan di Rumah Asosiasi Mikoriza Indonesia (AMI) cabang Sulawesi Tenggara selama 1 bulan (Mei). Penelitian ini menggunakan rancangan acak lengkap (Ral Faktorial) dengan tiga kali ulangan dan tiap unit 50 biji. Hasil penelitian menunjukkan bahwa benih tanpa skarifikasi memiliki nilai tertinggi pada peubah rata-rata waktu untuk berkecambah yaitu 10.58 hari. Penyimpanan benih 1 tahun mempunyai nilai tertinggi pada peubah persentase kecambah = 67,50%, daya kecambah = 66,50% dan rata-rata benih berkecambah perhari = 1,12 benih dan tidak berpengaruh signifikan terhadap perkecambahan benih. Perlakuan skarifikasi signifikan terhadap persen kecambah = 91.33%, daya kecambah = 91.00%, dan rata-rata benih berkecambah perhari = 1.52 benih. Benih kayu kuku perlu diskarifikasi sebelum dikecambahkan untuk mempercepat perkecambahan. Kata Kunci: kayu kuku, skarifikasi, perkecambahan The Effect of Scarification and Seed Storage Duration on The Viability of Kuku Wood Seeds (Pericopsis mooniana[Thw]Thw.)Abstract: Kayu kuku [Pericopsis mooniana (Thw) Thw.] is one of the species in the family Fabaceae. Kayu kuku is reportedly included in the local Sulawesi timber species which is currently in endangered category. This study aims to determine the viability of kayu kuku seeds which influences by scarification and the length of seed storage. This research carried out at the Indonesian Mycorrhiza Association greenhouse in the Southeast Sulawesi for one month (May 2019). This study used a completely randomized design on Factorial Ral with three replications and each unit of 50 seeds.The results showed that the seed without scarification had the highest value on the average time to germinate variable, which was 10.58 days. One year seed storage has the highest value on the variable percentage of germination = 67.50%, sprouts power = 66.50% and the average germination rate per day = 1.12 seeds and no significant effect on seed germination.Significant scarification treatment of sprout percent = 91.33%, germination power = 91.00%, and average germinating seeds per day = 1.52 seeds. The seed of Kayu Kuku needs to be clarified before germination to accelerate germination. Key words: Kayu kuku, scarification, Germination
