چکیده

AbstractPinching and dormancy breaking chemicals (DBC) application are potentially used to regulate the growth of plant. This study aims evaluate response ‘Crystal’ guava (Psidium guajava L.) seedling in pinching DBC application. experiment was carried out Integrated Field Laboratory, Faculty Agriculture, Universitas Lampung from March June 2021, with a randomized completely block design (RCBD) 2 factors (pinching DBC) repeated four times. The results showed that could reduce increase height seedling. combination significantly number new emerging leaves, branches, shoots as well length shoots. leaf area on leaves not affected by factors. non-pinched plants inhibited vegetative precisely increased generative growth, indicated flowers produced. most recommended treatment improve plant seedlings KNO3 40 g L-1.Keywords: 'Crystal' guava, KNO3, pinching, chemicals. AbstrakPinching dan pemberian zat pemecah dormansi berpotensi untuk digunakan sebagai pengatur pertumbuhan tanaman. Penelitian ini bertujuan mengevalusi respon bibit tanaman jambu biji 'Kristal' terhadap perlakuan (ZPD). Percobaan dilaksanakan di lahan Laboratorium Lapang Terpadu, Fakultas Pertanian, dari bulan Maret hingga Juni dengan rancangan acak kelompok (RAK) faktorial ZPD) yang diulang sebanyak 4 kali. Hasil penelitian menunjukan bahwa teknik dapat menurunkan pertambahan tinggi jambu. Namun hal justru memperbaiki Kombinasi ZPD meningkatkan jumlah daun, cabang, tunas baru serta panjang secara signifikan. Luas daun tidak dipengaruhi oleh faktor ZPD. Pemberian pada dipinching menghambat vegetatif, sebaliknya pertumbuhaan generatif indikator peningkatan bunga diproduksi. Perlakuan paling direkomendasikan vegetatif adalah kombinasi antara L-1.Kata kunci: ‘Kristal’,
