Permintaan anggur di Indonesia terus meningkat, namun produksi dalam negeri masih belum mampu memenuhi kebutuhan pasar sehingga diperlukan upaya peningkatan budidaya, antara lain melalui penggunaan batang bawah yang sesuai dengan metode grafting. Penelitian ini bertujuan mengevaluasi kompatibilitas grafting, pertumbuhan vegetatif, pembungaan, dan respon fisiologis tanaman anggur varietas Pestrij pada beberapa varietas batang bawah. Penelitian terdiri atas dua percobaan menggunakan Rancangan Acak Lengkap dengan tiga varietas batang bawah, yaitu Isabella, Red Master, dan Dodgride. Percobaan pertama mengevaluasi kompatibilitas grafting dan pertumbuhan bibit, sedangkan percobaan kedua mengamati pertumbuhan vegetatif, pembungaan, dan respon fisiologis tanaman setelah perlakuan stress air. Hasil penelitian menunjukkan bahwa Red Master menghasilkan persentase keberhasilan grafting tertinggi sebesar 90%, diikuti Isabella sebesar 85% dan Dodgride sebesar 70%. Isabella memberikan pertumbuhan vegetatif terbaik yang ditunjukkan oleh tinggi bibit, jumlah daun, diameter batang, dan jumlah cabang sekunder yang lebih tinggi dibandingkan perlakuan lainnya. Perbedaan antar varietas batang bawah terutama terlihat pada fase awal pertumbuhan tanaman. Sebaliknya, jumlah infloresens, jumlah bunga, kandungan karbohidrat, nitrogen, dan rasio C/N tidak berbeda nyata antar perlakuan. Perlakuan stres air cenderung meningkatkan kandungan karbohidrat dan rasio C/N pada seluruh perlakuan. Secara umum, Isabella berpotensi digunakan sebagai batang bawah yang sesuai untuk mendukung pertumbuhan vegetatif awal anggur varietas Pestrij pada kondisi tropis.

| dc.description.abstract | ABSTRACT
The demand for grapes in Indonesia continues to grow, but domestic production is limited. Rootstock selection is an important approach to improving grafting success and the early establishment and adaptation of the vine in tropical production systems. This study was carried out to assess the compatibility, vegetative growth, flowering response, and some physiological traits of Pestrij grapevines grafted onto Isabella, Red Master, and Dogridge rootstocks in greenhouse conditions in Bogor, West Java, Indonesia. Two experiments were performed in a completely randomized design. The first experiment evaluated grafting success and seedling growth with 20 plants per rootstock. The second experiment assessed vegetative growth, flowering, and carbohydrate and nitrogen status after a short water-stress induction treatment, with three experimental units per rootstock and three plants per unit. Red Master had the highest grafting success rate (90%), followed by Isabella (85%) and Dogridge (70%). Nevertheless, Isabella consistently supported faster early vegetative growth, including seedling height, number of leaves, lower stem diameter, secondary branching, and final stem diameter, compared with the other rootstocks. On the other hand, rootstock had no significant effect on the number of inflorescences, the number of flowers, carbohydrate content, nitrogen content, and C/N ratio. Water stress generally increased carbohydrate content and the C/N ratio, but this response did not significantly improve flowering. The results of the study show that all rootstock varieties tested exhibit good grafting compatibility with the Pestrij grapevine scion, whereas the Isabella variety is better suited to support the early vegetative growth of Pestrij grapevines in a tropical greenhouse environment.
