Abstract

Gamma-ray irradiation on plant seeds can affect plants’ growth and biochemical content. The application of gamma-ray irradiation can improve the quality of plants. This research aims to investigate the effect of gamma irradiation on the germination, growth, and chlorophyll content of sengon. Sengon seeds were irradiated with gamma rays at 0 (control), 25, 75, 125, and 175 Gy dose. Sengon seeds germinated and rared for four months. The study used a one-factor, completely randomized design (CRD). The parameters observed were the germination percentage, seedling height, diameter, and chlorophyll content. The result showed that gamma irradiation treatment can increase seed germination. Seeds irradiated with a dose of 75 Gy had a higher germination percentage than the other doses. Gamma irradiation with a dose of 25-175 Gy had of height and diameter of the seedlings compared to the control. Seedlings irradiated with a dose of 125 Gy had a higher chlorophyll content than other doses. Seedlings irradiated with a dose of 75 Gy had lower chlorophyll content than other doses. Therefore, in further experiment dose of gamma irradiation 25-175 Gy can be used to improve seeds’ viability. To increase the height and diameter of the seedlings, further research is still needed to investigate the effect of other doses on the growth of the seedlings.

Abstract

Infeksi cendawan terbawa benih merupakan salah satu faktor pembatas dalam pengembangan hutan tanaman sengon. Cendawan yang terbawa benih bisa menjadi penyebab penyakit dan dapat menurunkan produktivitas. Penelitian ini bertujuan untuk mengkaji pengaruh iradiasi sinar gama terhadap kesehatan benih sengon. Benih sengon diradiasi sinar gama dengan dosis 0, 25, 75, 125, dan 175 Gy. Uji kesehatan benih sengon dilakukan dengan menggunakan metode blotter test. Cendawan yang muncul pada benih diidentifikasi berdasarkan ciri morfologi. Hasil penelitian menunjukkan bahwa terdapat delapan jenis cendawan patogen terbawa benih yang teridentifikasi pada benih kontrol dan yang diiradiasi sinar gama, yaitu Aspergillus flavus, Aspergillus niger, Cladosporium sp., Penicillium sp., Phoma sp., Rhizopus sp., Pythium sp., dan Culvularia sp. Jenis Cladosporium sp., Penicillium sp., dan Phoma sp., mendominasi infeksi dan kontaminasi benih sengon pada setiap dosis iradiasi sinar gama. Perlakuan iradiasi sinar gama dengan dosis hingga 175 Gy belum efektif menurunkan nilai persentase infeksi cendawan terbawa benih sengon.
