Abstract

Penelitian ini bertujuan untuk mempelajari pengaruh interaksi antara konsentrasi zat pengatur tumbuh 2,4-D dan kinetin terhadap induksi kalus dari eksplan daun kayu manis serta untuk mendapatkan kombinasi konsentrasi yang tepat untuk menginduksi kalus. Penelitian dilaksanakan di Laboratorium Bioteknologi Tanaman Fakultas Pertanian, Universitas Jambi, Desa Mendalo Darat, Kecamatan Jambi Luar Kota, Kabupaten Muaro Jambi, Jambi. Penelitian menggunakan Rancangan Acak Kelompok (RAK) dengan pola faktorial, faktor pertama taraf konsentrasi zat pengatur tumbuh 2,4-D 1,2,3,4,5 ppm dan faktor kedua taraf konsentrasi zat pengatur tumbuh kinetin 0,1 ; 0,5 ; 1.0 ppm sehingga di dapatkan 15 perlakuan, setiap perlakuan diulang sebanyak 3 kali maka di dapatkan 45 satuan percobaan. Masing-masing satuan percobaan terdiri dari 3 botol dan terdapat satu eksplan dalam setiap botol. Eksplan di induksi selama 3 bulan. Parameter yang diamati yaitu waktu muncul kalus diamati 2 hari setelah tanam sampai 3 bulan, warna kalus, struktur kalus, persentase eksplan membentuk kalus dan berat kalus diamati di akhir penelitian. Hasil penelitian menunjukkan pada parameter waktu muncul kalus tercepat 15,33 HSK dengan pemberian zat pengatur tumbuh 2,4-D 1 ppm. Semua perlakuan dapat menginduksi kalus 100% dan terdapat berbagai variasi warna yang dihasilkan. Serta kalus yang dihasilkan kalus berstruktur remah dan kompak.

Abstract

This study was aimed to obtain the composition of ameliorant that gives the best result in recovering several chemical properties of coal post mining area in reclamation as well as in promoting the growth of avocado in the area. The study was carried out in post mining area of PT Nan Riang from April to October 2017 using Experimental Method with Randomized Group Design consisting of 5 treatments with different composition of ameliorant, a1 = 1 kg composted chicken manure + limestone (0,50 x Al-dd) + 25 g biochar /plant, a2 = 2 kg composted chicken manure + limestone (1,00 x Al-dd) + 50 g biochar /plant, a3 = 3 kg composted chicken manure + limestone (1,25 x Al-dd) + 75 g biochar /plant, a4 = 4 kg composted chicken manure + limestone (1,50 x Al-dd) + 100 g biochar /plant dan a5 = 5 kg composted chicken manure + limestone (1,75 x Al-dd) + 125 g biochar /plant. The results showed that the treatment by ameliorant composition had real influence on the increase of the plant’s height, unreal influence on the increase of the plant’s diameter, real influence on the soil pH, and unreal influence on the soil organic-C content and cation-exchange capacity. Also, it can be seen from the DMRT 5% test that the best composition of ameliorant in promoting the plant’s height was at 4 kg composted chicken manure+ limestone (1,50 x Al-dd) + 100 g biochar /plant, while that in improving the soil pH was at 5 kg composted chicken manure + limestone (1,75 x Al-dd) + 125 g biochar /plant.

Abstract

Cempedak seeds are recalcitrant seeds with high water content and are susceptible to a decrease in water content. Seed viability quickly decreases and eventually dies. Decreasing the water content below the critical point is a problem, high water content seeds germinate, and die if stored at low temperatures. With the right storage media, it is hoped that seeds can be stored longer so that seed viability and vigor can be maintained. This research aims to obtain appropriate storage media with a certain storage time that can maintain the viability and vigor of cempedak seeds. The research used a Completely Randomized Design (CRD) arranged factorially with two factors.  The first factor of storage media (m) consists of m1: sawdust, m2: rice husks, and m3: coconut fiber powder. Meanwhile, the second factor is storage time (w) which consists of three treatment levels, namely w1: storage for 2 weeks, w2: storage for 4 weeks and w3: storage for 6 weeks.  There were 9 treatments. Each treatment was repeated three times so that there were 27 experimental units. Each experimental unit contained 25 cempedak seeds. The variables observed were: seed water content, germination percentage, germination speed, germination uniformity and seedling dry weight. Data were analyzed using the F test and continued with the Duncan test at the α level of 5%. The results of the research showed that cempedak seeds stored in sawdust media for 4 weeks were able to maintain a water content of 36.24%, germination capacity of 69.33%, germination speed of 1.87%, germination simultaneity of 62.66% and seed dry weight. 8.37 grams.Key words: viability ; vigor ; storage media ; storage time; cempedak seeds
