Penelitian ini bertujuan untuk: 1) mengetahui pengaruh lamanya stres air terhadap pembungaan kelengkeng, 2) mengetahui pengaruh dosis KClO3 terhadap pembungaan kelengkeng, 3) menentukan kombinasi lamanya stres air dan dosis KClO3 yang terbaik untuk merangsang pembungaan kelengkeng. Penelitian ini dilaksanakan di Cilengko Farm, Desa Pandak, Kecamatan Baturraden dan di laboratorium Agronomi dan Hortikultura Fakultas Pertanian, Universitas Jenderal Soedirman pada Juli 2016 sampai Desember 2016. Rancangan yang digunakan adalah rancangan acak kelompok lengkap (RAKL) dengan dua faktor, yang terdiri dari lamanya stres air (tanpa pemberian stres air, stres air selama 2 minggu, dan stres air selama 3 minggu) dan dosis KClO3 (tanpa pemberian KClO3, 5 ml/l, 10 ml/l, 15 ml/l), sehingga terdapat 12 kombinasi perlakuan. Masing-masing perlakuan diulang sebanyak 3 kali dan terdapat dua unit percobaan untuk masing-masing ulangan. Variabel yang diamati meliputi jumlah daun (helai), luas daun (cm2), pertambahan tinggi tanaman (cm), kandungan klorofil (unit), saat muncul bunga (hsp), jumlah bunga rontok (%), dan jumlah bunga tidak rontok (%).Data dianalisis menggunakan uji F dan dilanjutkan dengan DMRT 5%. Hasil penelitian menunjukkan bahwa 1) pemberian perlakuan stres air hanya dapat dilihat pengaruhnya pada jumlah daun, dan dianggap belum mampu merangsang pembungaan kelengkeng, 2) pemberian perlakuan KClO3 hanya dapat dilihat pengaruhnya pada jumlah daun, dan dianggap belum mampu merangsang pembungaan kelengkeng, 3) Kombinasi antara pemberian stres air dan KClO3 belum mampu merangsang pembungaan kelengkeng.

This study aims to: 1) determine the effect of duration of water stress on the flowering of longan, 2) determinate the effect of dose of KClO3 on the flowering of longan, 3) determine the combination of duration of water stress and dose of KClO3 of the best for stimulate the flowering of longan. This research was conducted in Cilengko Farm, Pandak village, District of Baturaden and in the laboratory of Agronomy and Horticulture Faculty of Agriculture, University of Jenderal Soedirman in July 2016 to December 2016. This research used a randomized complete block design (RCBD) with two factors, consisting the duration of water stress (not given water stress, water stress for 2 weeks, and water stress for 3 weeks) and dose of KClO3 (not given KClO3, 5 ml/l, 10 ml/l, 15 ml/l), so there were 12 combinations of treatments. Each treatment was repeated 3 times and there were two experimental units for each replicate. The observed variables include the number of leaves (leaf), leaf area (cm2), increase plant height (cm), chlorophyll content (unit), the emergence of flower (hsp), number of flower does fall out (%), and number of flower does not fall out (%).The data were analyzed using the F test and continued with DMRT 5%. The results showed 1) the treatment of water stress performed visible effect on the number of leaves, and was not capable to stimulate the flowering of longan, 2) the treatment of  KClO3 performed visible effect on the number of leaves, and was not capable to stimulate the flowering of longan, 3) a combination of the treatment of water stress and KClO3 was not able to stimulate the flowering of longan.
