Slip and Accession Difference on Drought Tolerance of Pineapple Seedlings Through Proline Level

Pineapple plants are commonly propagated through slips. This research was conducted in the Experimental Garden of Sukamerindu Village, Sungai Serut Subdistrict, Bengkulu City. The study aimed to determine the effect of slips and accessions on the drought tolerance of pineapple seedlings, specifically by measuring the proline level. The study used a completely randomized design with two treatments: slip weight (B1 and B2) and accessions (A1-A25). There were a total of 50 treatment combinations, and the experiment was repeated three times, resulting in 150 plants. The results showed that there was no interaction between slip weight and accession on the growth of the seedlings. Accession had a significant effect on plant height and number of leaves, but did not significantly affect leaf greenness and stomatal density. Slip weight had a highly significant effect on plant height and number of leaves, but did not significantly affect leaf greenness and stomatal density. The highest proline content was found in Accession Babat-1 at 0.541 μmol proline/gram, while the lowest proline content was found in Accession Alai 2 at 0.345 μmol proline/gram. This suggests that Accession Babat-1 is more resistant to drought stress compared to Accession Alai 2.
