Pertumbuhan Rumput Laut Gracilaria sp. terhadap Variasi Dosis Media Walne

نویسندگان

چکیده

Gacilaria sp. merupakan sumber agar yang sangat laku di pasaran baik dalam negeri maupun luar negeri. Untuk memenuhi permintaan pasar maka stok bibit harus terpenuhi salah satunya dengan menggunakan metode vegetatif. Nutrien satu faktor penting proses ini. Jika media tumbuh tidak mencukupi kebutuhan perlu dilakukan pemupukan. Penelitian ini bertujuan untuk mengetahui pengaruh variasi dosis Walne pada pertumbuhan Gracilaria dan optimal sebagai nutrien. Metode digunakan adalah eksperimental laboratoris Rancangan Acak Lengkap (RAL) 5 perlakuan 1 kontrol 3 ulangan, antara lain A (kontrol), B (0,5 ml/L), C (1 D (2 E (4 ml/L) F (8 ml/L). Parameter diamati berat eksplan, jumlah tunas, panjang mutlak, laju spesifik kualitas air media. Data dianalisis analisis One-Way ANOVA dilanjutkan uji Tukey Games-Howell. Hasil penelitian menunjukkan rata-rata berat, tunas terdapat perbedaan signifikan (p < 0,05). Rata-rata mutlak tertinggi yaitu 0,07 ± 0,01 g/hari 2,24 %/hari. Hal diduga nutrien bekerja secara optimal. pengamatan pH – 7,92), salinitas (23 32 ppt) suhu (27 31 oC). Dosis 4 ml/L konsentrasi karena berpengaruh signifikan. is a source of which very salable in the market both domestically and abroad. To meet demand, stock seeds must be met, one them by using vegetative method. Nutrients are important factors process this If growing not sufficient, fertilization needs to done. This study aims determine effect variations dose on growth knowing as nutrients. The method used laboratory experimental with Completely Randomized Design (CRD) treatments control replications, including treatment (control), Parameters observed were explant weight, number shoots, shoot length, absolute weight growth, specific rate water quality analyzed analysis followed Games-Howell tests. results showed that there significant differences average shoots length highest was g/day 2,24%/day. It suspected nutrients work optimally. for salinity temperature concentration because at effect.

Different regulation of haloperoxidation during agar oligosaccharide-activated defence mechanisms in two related red algae, Gracilaria sp. and Gracilaria chilensis.

The related red seaweeds Gracilaria sp. from the eastern Mediterranean and Gracilaria chilensis from Chile were similar in their enzymatic inventory for halogenation. In both species, halogenation was dependent upon H(2)O(2) and thus driven by haloperoxidases. These could be inhibited with phosphate and reversibly inhibited with azide and were therefore apparently dependent upon vanadate. Both ...

Removal of Hexavalent Chromium Using Activated Carbons Derived from Marine Algae Gracilaria and Sargassum Sp

Industrial wastewater contain higher quantities of salts besides chromium (VI) ions, therefore, the effect of these salts on the adsorption of chromium (VI) should be studied. In this research, the batch removal of toxic hexavalent chromium ions from wastewater and aqueous solution using two different activated carbon marine algae Gracilaria (red algae) and Sargassum sp. (brown algae) were exam...

The lipidome of the red seaweed Gracilaria sp., cultivated on land-based integrated multitrophic aquaculture (IMTA) system, was assessed for the first time using hydrophilic interaction liquid chromatography-mass spectrometry and tandem mass spectrometry (HILIC-MS and MS/MS). One hundred and forty-seven molecular species were identified in the lipidome of the Gracilaria genus and distributed be...
