Abstract

ABSTRACT Arrangement of Guava Flowering (Psidium guajava L.) ‘Krystal’ through the Application of Different Strangulation Times. The seasonal production of guava (Psidium guajava) requires flowering manipulation technique such strangulation in order to be available throughout the years. This study aimed to explain the relationship between strangulation time, the period of flowering and harvesting of guava cv 'Krystal'. The experiment was conducted from February to December 2017, in Cikabayan experimental garden of IPB University, Bogor, Indonesia. The experiment used a completely randomized design with single factor, i.e strangulation times that consisted of control (no strangulation), strangulation in March, in April and in May. The results showed that strangulation treatment was able to accelerate the emergence of flowers and increase the number of generative shoots, the number of flowers per tree and the number of fruits harvested. The increase of flowering response on strangulated trees was supported by a higher leaf C/N compared to control, which is related to the low leaf N content in strangulation treatments. The strangulation treatment could accelerate the time of flower emergence six days earlier than control.  Keywords: guava, C/N, flowering induction, ringing, seasonal production ABSTRAK Produksi buah jambu biji (Psidium guajava) yang bersifat musiman memerlukan teknik pengaturan pembungaan agar dapat tersedia sepanjang tahun. Penelitian ini bertujuan untuk menjelaskan keterkaitan antara waktu strangulasi dengan pola pembungaan dan panen buah jambu biji ‘Kristal’. Percobaan dilaksanakan mulai Februari sampai Desember 2017, di Kebun Percobaan Cikabayan IPB Bogor. Rancangan yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan faktor tunggal yaitu waktu strangulasi yang terdiri dari 4 (empat) taraf, yakni tanpa strangulasi, strangulasi bulan Maret, strangulasi bulan April dan strangulasi bulan Mei. Hasil penelitian menunjukkan bahwa perlakuan strangulasi mampu mempercepat munculnya bunga dan meningkatkan jumlah tunas generatif, jumlah bunga per pohon, jumlah bakal buah per pohon dan jumlah buah yang dipanen. Peningkatan respon pembungaan akibat strangulasi didukung oleh C/N daun yang lebih tinggi dibandingkan tanpa stangulasi, yang berhubungan dengan rendahnya kandungan nitrogen daun pada perlakuan strangulasi. Perlakuan strangulasi mampu mempercepat waktu muncul bunga 6 hari lebih cepat dibandingkan tanpa strangulasi.Kata kunci: jambu biji, C/N, induksi pembungaan, pencekikan batang, produksi musiman
