Induksi partenokarpi dengan GA3 pada zucchini (Cucurbita pepo L)
Abstract
Sari Buah zucchini partenokarpi dihasilkan agar lebih efisien dalam pengolahan sebagai bahan pangan. Penelitian bertujuan untuk mengetahui pengaruh aplikasi GA3 dan waktu aplikasi terhadap partenokarpi. Penelitian dilakukan dengan penyemprotan GA3 pada perlakuan 0 ppm pollinated; 0, 500, 1.000, 1.500 ppm unpollinated; yang diaplikasikan pre anthesis dan anthesis. Perlakuan menggunakan metode Rancangan Acak Kelompok (RAK) Faktorial dengan tiga ulangan. Analisis varian menggunakan Uji Fdengan tingkat kepercayaan 95%. Uji lanjut menggunakan Tukey pada taraf nyata 5%. Perangkat lunak yang digunakan untuk analisis data adalah Minitab 17. Hasil penelitian pada konsentasi 1.500 ppm dan waktu aplikasi pre anthesis responsif dalam induksi partenokarpi pada buah zucchini.

Abstract. Parthenocarpy zucchini fruit is produced to be more efficient in processing as food. This experiment aimed to determine the effect of GA3 application and time of application on parthenocarpy fruit formation in zucchini. The GA3 treatment was carried out by spraying 0 ppm to pollinated flower; 0 500, 1000, and 1500 ppm to unpollinated flower. GA3 was applied at pre anthesis and anthesis. This experiment was arranged using Factorial Randomized Block Design (RBD) with three replications. Analysis of variance using the F Test with a confidence level of 95% followed with Tukey at the 5% significance level using Minitab 17. The experimental results showed that the concentration of 1000 ppm applied at pre anthesis were responsive in producing parthenocarpy zucchini fruit.
Keywords: parthenocarpy, GA3, zucchini, seed number, concentrate
