Abstract
Coconut water contains natural auxin growth regulators which are useful in stimulating root cuttings. This study aims to obtain the optimum of concentration of coconut water on the roses of cutting. The research was conducted from August to October 2018, in Pasir Sereh Village, Cihideung Village, Parompong District, West Bandung Regency, West Java Province. This study used a Randomized Block Design (RBD) with 6 treatments and 4 replications, namely A (Control), B (Concentration of 10% Coconut Water), C (Concentration of 20% Coconut Water), D (30% Concentration of Coconut Water), E (40% Concentration of Coconut Water), F (50% Concentration of Coconut Water). The parameters measured in this study were germination age, number of shoots, number of leaves, leaf area, root length, and root volume. The results showed no concentration optimum of coconut water which had a good effect on the growth shoot and root of stem cuttings of roses. At concentrations of 10%, 20%, 30%, 40%, and 50%, the growth shoot and root of rose cuttings was not different effect that without treatment.

Pada Tabel 1 dapat terlihat bahwa perlakuan C (20%) dan perlakuan E (40%) menghasilkan jumlah daun yang lebih banyak dari pada perlakuan B (10%) akan tetapi berpengaruh tidak nyata dengan perlakuan A (0%), D (30%) dan F (50%)
Hal ini berarti perlakuan C (20%) dan E (40%) tidak berbeda nyata dengan tanaman mawar yang tanpa memakai perlakuan
Summary
Umur bertunas Hasil analisis varian menunjukkan perlakuan berbagai konsentrasi air kelapa memberikan pengaruh yang sama terhadap umur bertunas setek tanaman mawar. Hasil analisis dengan Uji Jarak Berganda Duncan pada taraf 5% disajikan pada Tabel 1. Pada Tabel 1 dapat dilihat bahwa pengaruh konsentrasi air kelapa terhadap umur bertunas tidak menunjukkan perbedaan yang nyata antar semua perlakuan. Penggunaan konsentrasi air kelapa dari 10% - 50% belum mampu mempercepat umur bertunas tanaman mawar
