    Aksesi Potensial Jarak Pagar (Jatropha curcas L.)
    (Badan Penelitian dan Pengembangan Pertanian, 2007) Sudarmo, Hadi; Bambang Heliyanto; Suwarso; Sudarmadji; Pusat Penelitian dan Pengembangan Perkebunan
    Penelitian ini bertujuan untuk mengidentifikasi aksesi potensial jarak pagar untuk medukung pengembangan jarak pagar. Sebanyak 421 aksesi hasil eksplorasi jarak pagar dievaluasi di KP. Asembagus. Tiap aksesi diwakili 10 tanaman dengan jarak tanam 2 m x 2 m. Parameter yang diamati meliputi tinggi tanaman, jumlah cabang, jumlah tandan, jumlah buah per-tandan, berat 100 biji, kadar rninyak dan produksi biji. Hasil evaluasi sampai dengan umur 9 bulan teridentifikasi 7 aksesi memiliki harapan produktivitas tinggi, yaitu HS-49 (1097.50 kg/ha), SP-16 (977.50 kg/ha), SP-38 (912.50 kg/ha), SP-8 (656.07 kg/ha), SM-33 (622.50 kg/ha), SP-34 (578.33 kg/ha), dan SM-35 (500 kg/ha). Terdapat korelasi positif dan nyata antara jumlah tandan per tanaman dan jumlah buah per tandan dengan produksi, dengan koefisien korelasi masing-masing 0.733 dan 0.829.

    Response of Five Kenaf Accessions to Shoot Regeneration
    (Pusat Penelitian dan Pengembangan Perkebunan, 1999) Purwati, Rully Dyah; Sudjindro; Sudarmadji; Balai Penelitian Tanaman Tembakau dan Serat
    This experiment was aimed to study response of fives kenfa accession to shoot regeneratioo and to establish an appropriate regeaeraiea protocol for kenaf The experiment was performed at Tissue Culture Laboratory Research Institute for Tobacco and Fibre Crops (RITFC), MaJang, from June to Octo- ber 1997. Crtyledons with plumules attached were used as explants and culture medium for callus induction was MS-based medium with BAP (2 mgfl) and NAA (0.5 mgfl). Calli produced in this cultures were transferred into MS-based medium containing BAP (2 mgfl) and GAJ (5 mgfl) for shoot initiatioo. All shorts obtained were then sub-cultured in MS-based medium without regulators (MSO) for root formation. Rooted shorts (plantlets) were acclimatized in the sterile sand and transferred into sterile soil in the glass house. Results of this experiment showed that the most respoosive accessions were Cuba 10811, followed by KK 60, He 48, PI 324922, aid CRNI 056 H with the average number of shoots per explant 4.32 ± 4.21, 4.00± 4.01, 3.05 ± 2.98, 2.80± 1.47, and 2.72 ± 2.49, respectively, at 40 days after transferring on shoot regeneratica medium. Shoots rooted after 14 days on MSO medium with frequencies of 81.50-93.30%. Healthy plaatlets survived and grew well in soil media in the glass house. Therefore, an appropriate short regeneration protocol for kenafwas found,
