Plantlet In Vitro

Phalaenopsis merupakan salah satu anggrek yang terkenal karena keindahan bunganya dengan variasi warna yang tinggi dan periode pembungaan yang lama. Salah satu masalah dalam budidaya anggrek adalah Penyakit Busuk Lunak (PBL) yang disebabkan oleh bakteri Dickeya dadantii. Induksi resistensi dengan Asam Salisilat (AS) merupakan metode alternatif dalam mengendalikan PBL pada Phalaenopsis. Penelitian ini dilaksanakan pada bulan November 2018 sampai Maret 2019, di Laboratorium Kultur Jaringan Tanaman, Departemen Agronomi dan Hortikultura IPB. Penelitian terdiri dari dua percobaan. Percobaan 1 bertujuan untuk mengevaluasi keragaman respon planlet in vitro asal biji hasil penyerbukan sendiri P. amabilis terhadap D. dadanti dengan inokulasi pada daun terpisah dan menentukan tingkat ketahanannya. Sebanyak 7 dari 158 planlet yang diuji, memiliki respon agak tahan terhadap D. dadantii, sedangkan sisanya rentan atau sangat rentan. Percobaan 2 bertujuan untuk membandingkan respon bibit P. amabilis terhadap D. dadantii pada 1 hari setelah perlakuan asam salisilat (AS) pada konsentrasi 0, 15, 30, 45, 60, 75, dan 90 ppm menggunakan metode inokulasi daun pada bibit yang masih menempel di tanaman. Percobaan 2 menggunakan rancangan acak kelompok lengkap teracak (RKLT). Hasil penelitian menunjukkan perlakuan AS 75 ppm paling baik dalam menginduksi ketahanan bibit P. amabilis terhadap patogen penyebab busuk lunak D. dadantii. Tanaman pada perlakuan tersebut menghasilkan nilai CFU dan AUPDC lebih rendah dan aktivitas peroksidase lebih tinggi dibanding perlakuan lainnya.

In order to determine the nitrogen use efficiency of plantlets in vitro under different nitrogen source, near infrared spectroscopy technique and image analysis technique with multi-references were used to obtain the successive information of nitrogen consumption. The Logistic and nonlinear hyperbolic equations were used for fitting the relationship of biomass of plantlet in vitro and culture time, nitrogen utilization of plantlets and culture time, and nitrogen utilization of plantlets and biomass of plantlet in vitro. The models of growth prediction, nitrogen utilization and nitrogen use efficiency of plantlets in vitro were established. The nitrogen use efficiency of Atractylodes lancea plantlets in vitro sub-cultured in different nitrogen source and levels were measured, which decreased with the increase of culture time. Ammonium (0.096 g L-1) / nitrate (0.555 g L-1) was the preferred nitrogen sources combination for the growth of Atractylodes lancea plantlets in vitro.
