Abstract

Research on the Effect of Cutting Scarification and Sulfuric Acid Concentration on Germination and Growth of Ajwa Date Seedlings (Phoenix dactylifera L.). This research was conducted in the Greenhouse area of ??the Faculty of Agriculture, Riau Islamic University, Jalan Kaharudin Nasution KM 11 No. 113, Marpoyan, Air Dingin Village, Bukit Raya District, Pekanbaru City. This research was conducted for 4 months starting from February to May 2024. The design used in this study was a Completely Randomized Design (CRD) factorial consisting of 2 factors. The first factor is Cutting scarification consisting of 5 levels, namely without cutting, cutting in the plumule area, cutting in the radicle area, cutting in the plumule and radicle areas, and cutting in the embryo area and the second factor is sulfuric acid consisting of 4 levels, namely 0 ml / L, 40 ml / L, 80 ml / L and 120 ml / L. The parameters observed were germination power, germination time, vigor index, number of leaves, longest leaf length, seedling height, longest root length, seedling wet weight, and seedling dry weight. The observation data were analyzed statistically and continued with the Honestly Significant Difference (HSD) test at the 5% level. The results showed that the interaction of the effect of cutting scarification and sulfuric acid had a significant effect on the parameters of germination power, germination time, vigor index, number of leaves, longest leaf length, seedling height, longest root length, seedling wet weight and seedling dry weight. The best treatment was cutting in the embryo area and 120 ml/L sulfuric acid (P4A3).
