Judul: Growth of Roots and Shoots of Mulwo Stem Cuttings  (Annona reticulata L.) with Auxin Administration
Abstrak: Tanaman mulwo (Annona reticulata L., Annonaceae) mirip dengan tanaman sirsak dan srikaya. Tanaman sirsak dan srikaya dapat dikembangbiakkan dengan cara generatif dan vegetatif. Perkembangbiakan vegetatif dengan stek dapat dilakukan melalui stek batang. Selain itu, diperlukan zat pemacu perakaran pada stek batang yaitu auksin. Namun, penelitian mengenai perbanyakan tanaman mulwo dengan stek batang belum banyak dilakukan. Penelitian ini bertujuan menentukan konsentrasi auksin yang sesuai untuk memacu pertumbuhan akar dan tunas pada stek batang tanaman mulwo. Rancangan penelitian yang digunakan adalah Rancangan Acak Lengkap (RAL). Perlakuan konsentrasi auksin (Rootone-F) yang digunakan terdiri dari 4 taraf yaitu 0 mg/mL, 2000 mg/mL, 4000 mg/mL, dan 10000 mg/mL. Perlakuan tersebut diulang sebanyak 5 kali ulangan. Parameter yang diamati adalah jumlah tunas, jumlah akar adventif, dan jumlah inisiasi akar. Hasil penelitian menunjukkan bahwa konsentrasi Rootone-F 2000 mg/mL merupakan perlakuan dengan jumlah tunas terbanyak dan dapat memacu munculnya inisiasi akar., Mulwo (Annona reticulata L., Annonaceae) is similar to soursop and srikaya. Soursop and srikaya plants can be propagated generatively and vegetatively. Vegetative propagation by cuttings can be done through stem cuttings. In addition, a rooting agent is needed for stem cuttings, namely auxin. However, research on the propagation of mulwo plants by stem cuttings has not been widely carried out. This study aims to determine the concentration of auxin to stimulate root and shoot growth on stem cuttings of mulwo plants. The research design used was a Completely Randomized Design (CRD). The concentration treatments of auxin (Rootone-F) consisted of 4 levels, namely 0 mg/mL, 2000 mg/mL, 4000 mg/mL, and 10000 mg/mL. The treatment was repeated 5 times. The parameters observed were the number of shoots, the number of adventitious roots, and the number of root initiations. The results showed that the concentration of Rootone-F 2000 mg/mL was the treatment with the highest number of shoots and could stimulate the emergence of root initiation.

Judul: Growth Response of Moringa Cuttings to Position of Cuttings and Application of Auxin
Abstrak: Kelor merupakan sayuran indigenous yang belum diperbanyak secara massif di Indonesia. Perbanyakan pada kelor dilakukan secara generatif dan vegetatif. Perbanyakan vegetatif dengan setek hanya menghasilkan satu bibit setek dengan presentase hidup 63,33%. Sehingga perlu dilakukan peningkatan jumlah setek dan presentase hidup setek. Penelitian ini bertujuan mempelajari respon pertumbuhan bahan tanam kelor berdasarkan posisi peletakan setek dan aplikasi auksin. Penelitian dilaksanakan mulai bulan Juli – Desember 2023 di Kebun Percobaan Cikabayan Atas. Percobaan dilakukan menggunakan rancangan acak lengkap dua faktor dengan 3 ulangan. Faktor pertama posisi setek dua taraf yaitu horizontal dan vertikal kemudian faktor kedua aplikasi auksin dua taraf yaitu tanpa auksin dan dengan auksin. Kandungan metabolit sekunder daun kelor pada penelitian ini untuk total flavonoid 0,52 – 0,67 mg g-1, antosianin 0,07 – 0,19 mg 100 g-1, karoten 0,77 – 0,83 mg 100 g-1, dan total fenol 4,99 – 5, 42 % (b/b). Hasil dari posisi peletakan setek, aplikasi auksin, dan interaksi kedua faktor pada tanaman kelor belum bisa dijadikan sebagai rujukan, karena tingkat populasi setek hidup sampai akhir pengamatan yang rendah. Hal ini disebabkan adanya serangan hama selama proses penelitian., Moringa is an indigenous vegetable that has not been cultivated on a large scale in Indonesia. Propagation of moringa is achieved through generative and vegetative means. Vegetative propagation with cuttings produces a single seedling with a live percentage of 63,33%. Therefore, enhancing the number of cuttings and the percentage of living cuttings is essential. This research aims to investigate the growth response of moringa planting material about the position of the cuttings and the application of auxin. The study was conducted between July and December 2023 at the Cikabayan Experimental Garden. The experiment was designed using a two-factor completely randomized design with three replications. The first factor was two levels of cutting position, horizontal and vertical, while the second was two levels of auxin application, namely without auxin and with auxin. The secondary metabolite content of moringa leaves in this research for total flavonoids 0,52 – 0,67 mg g-1, anthocyanins 0,07 – 0,19 mg 100 g-1, carotene 0,77 – 0,83 mg 100 g-1, and total phenols 4,99 - 5, 42% (b / b). However, the results of the position of the cuttings, the application of auxin, and the interaction of the two factors cannot be used as a reference, as the population level of live cuttings until the end of observation was low. This was due to pest attacks during the research process.
