Description The study aimed to obtain morphophysiology information on fruit-drop events in chili plants on application of plant growth regulator (PGR) auxin (IAA and IBA) and gibberellins. The study was arranged based on a split-plot design in a randomized block design with 3 replications. The main plot is 3 types of PGR namely IAA, IBA, and GA3. The subplots are 5 levels of concentrations (ppm): 0, 25, 75, 50, and 100. The data were analyzed using STAR software and Smallest Significant Difference (LSD) 5%. The results showed that the application of PGR and concentration did not significantly affect the number of attached and abscised flowers. However, the application of PGR resulted in a higher number of attached flowers than the abscised flowers. Giving IAA 25 ppm produced the highest number of fruits compared to other IAA concentrations. Increasing the concentration of GA3 tends to increase the number of attached fruits and the highest at 100 ppm GA3. The interaction between PGR and concentration significantly affected the weight per fruit. The treatment of GA3 100 ppm produces the highest weight per fruit. Increasing the concentration of auxin tends to reduce the weight per fruit. The IBA 100 ppm decreases the length of chili.
Penelitian bertujuan mendapatkan data dan informasi morfofisiologi kejadian gugur bunga dan buah (fruit-drop) pada tanaman cabai terhadap pemberian zat pengatur tumbuh (ZPT) auksin (IAA dan IBA) dan GA3. Penelitian disusun berdasarkan Rancangan Petak Terpisah dalam rancangan acak kelompok dengan 3 ulangan. Petak utama adalah 3 jenis ZPT yaitu IAA, IBA, dan GA3. Anak petak yaitu konsentrasi perlakuan yang terdiri dari 5 taraf (ppm) yaitu 0, 25, 50, 75, dan 100 ppm. Data yang diperoleh dianalis menggunakan software STAR dan jika terdapat beda nyata diuji lanjut dengan Beda Nyata Terkecil (BNT) pada taraf 5%. Hasil penelitian menunjukkan bahwa perlakuan IAA, IBA, dan GA3 serta konsentrasi perlakuannya tidak berpengaruh nyata terhadap jumlah bunga tinggal maupun bunga gugur pada tanaman cabai besar. Namun, hasil penelitian menemukan bahwa perlakuan ZPT menghasilkan jumlah bunga tinggal yang lebih banyak dibandingkan bunga gugur. Pemberian IAA 25 ppm menghasilkan jumlah buah tinggal tertinggi dibandingkan konsentrasi IAA lainnya. Peningkatan konsentrasi GA3 cenderung meningkatkan jumlah buah tinggal dan tertinggi pada konsentrasi GA3 100 ppm. Interaksi antara jenis ZPT dan konsentrasi pemberiannya berpengaruh nyata terhadap bobot per buah. Perlakuan GA3 100 ppm menghasilkan bobot per buah tertinggi. Peningkatan konsentrasi auksin cenderung menurunkan bobot per buah. Pemberian IBA 100 ppm menurunkan panjang buah cabai besar.
