Abstract
Penelitian ini bertujuan untuk mengetahui respon pertumbuhan pegagan (Centella asiatica (L.) Urban) pada perlakuan kombinasi konsentrasi, tempat pemberian dan frekuensi pemberian zat pengatur tumbuh kinetin. Rancangan penelitian yang digunakan adalah Rancangan Acak Kelompok (RAK) faktorial yang terdiri dari 3 faktor, dengan ulangan sebagai kelompok. Faktor pertama adalah konsentrasi kinetin (0, 20, 40, 60, 80 dan 100 ppm) masing-masing sebanyak 10 ml. Faktor kedua adalah tempat pemberian (disemprotkan di lamina daun dan di pangkal tangkai) dan faktor ketiga adalah frekuensi pemberian kinetin (1x yang dilakukan pada minggu pertama dan 2x pada minggu pertama dan minggu ketiga setelah tanam selama 3 bulan). Masing-masing perlakuan diulang 3 kali. Panjang tangkai daun, luas daun, jumlah tangkai daun, panjang stolon, jumlah stolon diamati seminggu sekali. Sedangkan panjang akar, jumlah akar, berat kering tanaman bagian atas, berat kering akar dan berat kering total diamati pada akhir bulan ke-3. Data dianalisis statistik dengan uji ragam dan uji BNJ α=5%. Hasil penelitian menunjukkan bahwa konsentrasi, tempat dan frekuensi pemberian kinetin tidak berpengaruh nyata terhadap panjang tangkai daun, luas daun, jumlah stolon, panjang akar pegagan dan berat kering akar. Frekuensi pemberian kinetin hanya mempengaruhi jumlah akar. Sedangkan jumlah tangkai, panjang stolon, berat kering tanaman bagian atas dan berat kering total hanya dipengaruhi oleh konsentrasi kinetin. Konsentrasi kinetin 20 ppm cenderung menghasilkan pertumbuhan jumlah tangkai, panjang stolon, berat kering tanaman bagian atas dan berat kering total terbaik. Hal ini berarti bahwa tanaman pegagan cenderung memberikan respon pertumbuhan yang lebih baik pada perlakuan kinetin dengan konsentrasi rendah.
English Abstract
The aims of this research were to examine effect of concentration, spraying place and frequency of kinetin on Pegagan (Centella asiatica (L.) Urban) growth. The research was designed using Factorial Randomized Complete Design with 3 factors. The first factor was concentration of kinetin (0, 20, 40, 60, 80 and 100 ppm) each 10 ml in volume. The second factor was place of kinetin sprayed (leaf and lower end of shoot leaf). The third was frequency of kinetin application during 3 month observation (once on first week and twice on first and third week). Each treatment was repeated 3 times. The repeation as a group. Shoot length, leaf area, shoot number, length and number of stolon were observed once a week. Length and number of root as well as shoot, root and total of biomass were measured only at the end of the observation. Data were analyzed by using analysis of variance and multivariate (tukey; α=5%). Result of the research showed that concentration, place and frequency of kinetin application did not significantly affect on shoot length, leaf area, stolon number, root length and root biomass. Frequency of kinetin application only affected on root number. Shoot number, stolon length, shoot and total biomass were influenced significantly by kinetin concentration. The 20 ppm kinetin significantly provided better growth than all other tested concentration for increasing shoot number, stolon length, shoot and total of biomass. This means that Pegagan has better growth responses by application of kinetin with low concentration.
