Konservasi vigor benih rekalsitran kakao (Theobroma cacao L.) dengan penurunan kadar air dan proses nvigorasinya

Abstract

Penelitian dilaksanakan dalam tiga tahap percobaan. Penelitian I terdiri dari dua percobaan : 1.1 Pengaruh kadar air terhadap viabilitas dan kebocoran membran, Percobaab 1.2. Pengaruh kadar air benih terhadap asam lemak bebas, bilangan peroksida, isoenzim (indikasi biokemis) dan viabilitasnya (indikasi fisiologis). Penelitian II. Studi kerusakan sel pada benih kakao berkadar air rendah.

The objective of this study experiment was to study the effect of desiccation and invigoration on viability of cacao seed during conservation period. The study consisted of three experiments. 1) Effect of desiccation on seed viability (physiological indication) and membrane leakege, free fatty acid, peroxidation value, isoenzyme peroxidase, esterase, acid phosphatase (biochemical indication), 2) Status of cellular damage on cacao seed due to desiccation, 3) Effect of desiccation and invigoration on respiration rate and seed viability.
