Abstract
ABSTRAK
Mentimun gynoecious sangat penting untuk produksi benih hibrida, namun secara alami hanya menghasilkan bunga betina, sehingga menyulitkan pemeliharaan galur murni. Penelitian ini bertujuan untuk menentukan konsentrasi zat penginduksi paling baik dalam menginduksi pembentukan bunga jantan pada tanaman mentimun gynoecious. Penelitian dilaksanakan di PT. Tani Murni Indonesia menggunakan Rancangan Acak Lengkap Petak Terpisah (split plot). Petak utama (Main Plot) yaitu varietas mentimun gynoecious (Erina, New Metavy dan Zatavy) dan anak petak (Subplot) zat penginduksi bunga jantan Silver Nitrat (AgNO3) (200 dan 300 ppm), Silver Tiosulfat (Ag2S2O3) (200 dan 500 ppm) dan Giberelin (GA3) (1000 dan 1500 ppm). Aplikasi perlakuan dilakukan dengan cara penyemprotan. Data pengamatan dianalisis menggunakan Sidik Ragam (ANOVA) taraf 5% dilanjutkan dengan DMRT taraf 5%. Hasil analisis data menunjukkan terdapat interaksi terbaik varietas Erina, New Metavy dan Zatavy memberikan hasil munculnya bunga jantan lebih cepat pada AgNO3 200 ppm, jumlah buah tertinggi pada perlakuan Ag2S2O3 200 ppm dan panjang buah terbaik pada perlakuan tanpa zat penginduksi. Zat penginduksi terbaik Silver Tiosulfat 200 ppm dan varietas terbaik Zatavy.
Kata Kunci: Varietas, Mentimun Gynoecious, Silver Nitrat, Silver Tiosulfat, Giberelin.
ABSTRACT
Gynoecious cucumbers are essential for hybrid seed production, but they naturally produce only female flowers, making it difficult to maintain pure lines. This study aimed to determine the optimal concentration of an inducer for inducing male flower formation in gynoecious cucumber plants. The study was conducted at PT. Tani Murni using a Split Plot Completely Randomized Design. The main plots consisted of gynoecious cucumber varieties (Erina, New Metavy, and Zatavy), and the subplots consisted of the male flower-inducing agents silver nitrate (AgNO₃) (200 and 300 ppm), silver thiosulfate (Ag₂S₂O₃) (200 and 500 ppm), and gibberellin (GA₃) (1000 and 1500 ppm). The treatments were applied via spraying. The observational data were analyzed using Analysis of Variance (ANOVA) at the 5% level, followed by DMRT at the 5% level. The results of the data analysis showed that the best interaction was between the Erina, New Metavy, and Zatavy varieties, resulting in earlier male flower emergence at 200 ppm AgNO₃, the highest fruit yield at 200 ppm Ag₂S₂O₃, and the best fruit length in the treatment without an inducer. The best inducing agent was 200 ppm silver thiosulfate, and the best variety was Zatavy.
