Abstract

Anyelir (Dianthus caryophyllus L.) merupakan salah satu komoditas bunga potong komersial yang sangat penting di dunia. Tanaman anyelir mempunyai susunan genetik yang heterozigot, tetapi tanaman F1 terseleksi dari hasil persilangan langsung dapat dijadikan tanaman induk sebagai sumber perbanyakan vegetatif. Setiap klon F1 berbeda secara genetik. Tujuan percobaan ialah mendapatkan klon-klon anyelir bunga potong yang memiliki kombinasi karakter morfologi tanaman dan bunga yang unggul. Percobaan dilaksanakan di rumah lindung Instalasi Penelitian dan Pengkajian Teknologi Pertanian (IP2TP) Cipanas, Cianjur, Jawa Barat, dengan ketinggian 1,100 m dpl, dari bulan Januari sampai dengan Desember 2019. Penelitian ditata dalam rancangan acak kelompok lengkap dengan sembilan perlakuan, yaitu : D 1.1, D 3.13, D 5.1, D 5.4, D 5.5, D 8.5, D 8.8, D 13.13 dan D 13.14 dan tiga ulangan. Hasil percobaan menunjukkan bahwa klon D 13.14 terpilih sebagai klon harapan anyelir bunga potong, karena memiliki kombinasi karakter morfologi tanaman dan bunga yang unggul, yaitu tanaman kokoh, diameter bunga besar (7.52 cm), jumlah petal terbanyak (87.67 helai), kesegaran bunga terlama (13.83 hari) dan warna bunga merah menyala.

Abstract

Impatiens hawkeri x platypetala rooted cuttings are typically cultivated using rice husks as a substrate. However, due to the poor water-holding capacity of this medium, Impatiens grows slowly in this environment. A viable alternative is the cocopeat perlite mixture which has a better water-holding capacity compared to the rice husk. Currently, there is no sufficient information available regarding the best growth medium to improve the quality of I. hawkeri x platypetala rooted cuttings in Indonesia. Therefore, this study aimed to obtain the best medium for quality rooted cuttings I. hawkeri x platypetala. The method employed was a randomized complete block design with two factors. The first factor was the Impatiens varieties consisting of Impala Agrihorti, Imadata Agrihorti, and Lavender, while the second was the growth medium, comprised of four levels namely rice husk (control), as well as a mixture of cocopeat with 3%, 5% and 8% perlite. The result showed that there was no interaction between varieties and growth medium. The mixture of 3% perlite in cocopeat exhibited better outcomes compared to other treatments. This medium increased the number and length of roots, stem diameter, plant height, leaves thickness, leaves number and survival rate. Therefore, the addition of 3% perlite in cocopeat could replace the rice husk as a rooted cutting growth medium for I. hawkeri x platypetala.
