Acclimatization of seaweed plantlets in the greenhouse is one of the stages of seaweed cultivation using tissue cultures techniques. Acclimatiation aims to adapt plantlets that were originally cultured in the laboratory under controlled condition to be cultivated in the water.
The purpose of this trial was to determine the optimal duration for acclimatization of plantlets in the greenhouse to produc e the best growth of Cottoni seedlings. The trial was conducted in the water around Main Centre for Marine Aquaculture Lampung. The treatments consist of the duration for acclimatization in the greenhouse for 2 weeks, 4 weeks and 6 weeks. The acclimatized plantlets were then cultivated in the water for 1 month.
The specific growth rate between acclimatization 2 weeks (2,92%) and 4 weeks (2,93%) was not significantly different but was significantly different from the 6 weeks treatment (2,57%).
The acclimatized plantlets were then cultivated in the water for 1 month and the results showed that the treatment between 2 weeks of acclimatization (7,11%) dan 4 weeks (7,25%) was not significantly different but was significantly different from the 6 weeks treatment (6,43%).
From the results it can be concluded that the most optimal plantlets acclimatization duration in the greenhouse is acclimatization for 2 weeks.
