Rice cultivation in Indonesia involves different types of rice, including red rice, which is known to have higher nutritional value compared to white rice. However, the germination rate of red rice seeds has decreased due to poor storage conditions. Nature Growth Regulators play a critical role in the success of seed germination, seedling establishment and subsequent plant growth. To improve the quality of red rice seeds, natural growth regulators can be used. In a recent study, researchers aimed to determine the best combination of natural growth regulators and concentration level for germination of red rice line. This research was conducted from July to October 2023 at the seed technology and agronomy laboratories of the Faculty of Agriculture, Universitas Andalas. This is a factorial experiment consisting of two factors arranged in random groups design and repeated four times. The first factor was the type of natural growth regulators, namely young coconut water and shallot extract. The second factor was the concentration level, namely 0%, 35%, 70%. The data were analyzed using the F-test with a 5% level of significance. If significant differences were found, Duncan's New Multiple Range Test (DNMRT) was conducted at a 5% level. The observation parameters for the germination test carried out were the maximum growth potential (%), seed germination (%), and hard seeds (%). The application of young coconut water on concentration 70% gave the best percentage of maximum growth potential and was not different with shallot extract on concentration 70%. The application of young coconut water on concentration 70% gave the best percentage of seed germination compare to other treatment.

Jamblang merupakan salah satu buah lokal Indonesia yang keberadaannya sudah jarang ditemukan. Jamblang dikenal oleh masyarakat Sumatera Barat khususnya Kota Padang sebagai jambu kaliang. Polen merupakan organ generative jantan dari tanaman yang berfungsi sebagai sarana utama pengalir gen pada persilangan spesies. Fertilitas adalah kemampuan polen atau bakal buah untuk tumbuh normal membentuk benih. Sedangkan sterilitas adalah kegagalan proses pembuahan karena ketidakmampuan pollen atau bakal buah untuk membentuk biji. Viabilitas polen merupakan persentasi polen yang akan menyelesaikan perkecambahan dan membentuk tabung sari (pollen tube). Penelitian ini bertujuan untuk mengatahui persentase polen tanaman jamblang yang fertile dan viable yang berguna bagi kegiatan pemuliaan tanaman. Pelaksanaan penelitian dilakukan dengan menggunakan metode pewrnaan dengan larutan bromothymol blue untuk mengamati fertilitas polen, dan pengujian vibilitas polen dengan metode Brewbaker dan Kwack (1964). Berdasarkan hasil pengamatan diketahui bahwa terdapat polen yang fertile pada semua genotype tanaman, akan tetapi tidak ada satupun polen yang mampu untuk berkecambah secara in vitro.
