Di Indonesia, tren penggunaan pohon buah sebagai tanaman penghijauan di perkotaan terus meningkat. Di sisi lain, karakterisasi agro-ekologi pohon buah sebagai tanaman penghijauan di perkotaan masih belum teridentifikasi dengan baik, termasuk faktor pembatas yang mempengaruhi pertumbuhan tanaman. Penelitian bertujuan untuk mengidentifikasi karakteristik agro-ekologi dan keragaman pohon buah sebagai tanaman penghijauan di pinggir jalan. Pemilihan objek pengamatan dalam penelitian ini adalah keragaman tanaman penghijauan yang ada di pinggir jalan Kota Bandung dengan metode transek mengikuti jalur jalan kendaraan. Secara umum, ditemukan 23 spesies tanaman penghijauan di pinggir jalan dengan 14 tanaman adalah pohon buah. Indeks keragaman Shannon-Wiener’s (H’) tanaman penghijauan pinggir jalan yakni 1.29-1.94 termasuk keragaman sedang. Indeks dominansi Simpson (C) berkisar antara 0.18-0.48, menunjukkan tidak ada jenis tanaman yang mendominasi pada setiap segmen jalan. Pohon kersen dapat ditemukan pada seluruh tipe jalan yang diamati, mengindikasikan pohon buah ini secara sengaja ditanam sebagai tanaman penghijauan pinggir jalan. Kajian lanjut pada 14 pohon buah di 11 ruas jalan menunjukkan faktor pembatas utama yang dihadapi adalah bawah pohon sebagai tempat usaha, kabel melintang di atas pohon, dan lokasi akar sempit. Asesmen risiko pohon buah secara keseluruhan tidak ditemukan tingkat risiko tinggi. Berdasarkan hasil tersebut dapat diambil kesimpulan bahwa pohon buah yang teridentifikasi laik dipertimbangkan sebagai tanaman penghijauan pinggir jalan dengan kajian lanjut berkaitan dengan karakteristik morfologi dan kesesuaian fungsi tanaman.

Moringa is drought tolerant and its leaf is traditionally used as a vegetable. Recently, the leaf is used commercially in traditional medicine and functional foods. Fulvic acid is a kind of plant growth regulator derived from humic acid and is considered a fertilizer in sustainable agriculture. The objective of the research was to determine the effect of fulvic acid concentration on the growth, biomass, phosphorus and flavonoids contents of moringa seedlings. The experiment was conducted from July 2020 to January 2021 at Leuwikopo Experimental Station, Bogor. The treatment was arranged in a randomized block design consisting of two factors, i.e., fulvic acid level (0, 1, 2, 3, and 4 mL L-1) and moringa accessions (East Nusa Tenggara-ENT and Leuwikopo-LWK). Observation focused on growth and biomass, total flavonoids, and phosphorus contents of leaves. The results showed that fulvic acid enhanced leaf growth, and plant height. On the other hand, the fulvic acid application had no significant effect on biomass production, total flavonoids, and phosphorus contents of moringa leaves. Accessions expressed different responses to fulvic acid levels, i.e.e, the fulvic acid of 1 mL L-1 seemed favorable for ENT accession while 2 mL L-1 was favorable for LWK accession as indicated by the level of flavonoid content. Therefore, fulvic acid is beneficial in moringa cultivation, particularly for ENT accession. It is interesting to evaluate the fulvic acid application on moringa trees grown in ENT where soil moisture is considered low.

The rootstock number and scion types can be used to optimize grafting success. This study aimed to determine the effect of rootstock number, scion type, and its interaction on the success of nutmeg grafting. The research was conducted at the Seed Breeding Site in Layeni Village, Central Maluku Regency, Maluku. The research started in November 2022 and ended in August 2023. The experiment used a two-factor completely randomized design. The first factor was the rootstock number, i.e., single, double, and triple rootstocks. The second factor was the scion type, i.e., Myristica fragrans Houtt, Myristica argentea Warb, and Myristica sp. The 9 treatment combinations were replicated six times, resulting in a total of 54 experimental units. The result of the study concluded that grafting success was influenced by the rootstock number and the scion types, and there was no interaction between rootstock and scion. The highest success was achieved by using a single rootstock with a success rate of 60%. The use of Myristica sp. scions gave the highest grafting percentage of 76.66%. Successful nutmeg grafting was characterized by the presence of a fusion between the rootstock and the scion, based on anatomical observations. Failed nutmeg grafting was characterized by the absence of fusion between rootstock and scion. The rootstock number and scion type affected shoot emergence time, linked stem diameter, shoot length, and leaf number, while the scion type affected the shoot number. Double rootstock tended to have higher parameters than single and triple rootstock for shoot emergence and leaf number, but the number of failed grafting was still challenging.
