GERMINATION OF SALAK (Salacca zalacca) SEEDS WITH CHEMICAL SCARIFICATION TREATMENT

Abstract

This study aims to determine the effect of KNO₃, H₂SO_4, and GA₃ in breaking dormancy and germination of salak (Salacca zalacca) plants. In this study using a non-factorial randomized block design with one factor, namely P₀ (control), P₁ (KNO₃ 60%), P₂ (KNO₃ 70%), P₃ (KNO₃ 80%), P₄ (H₂SO₄ 60%), P₅ (H₂SO₄ 70%), P₆ (H₂SO₄ 80%), P₇ (GA₃ 25 ppm), P₈ (GA₃ 50 ppm), P₉ (GA₃ 75 ppm), P₁₀ (KNO₃ 60% and GA₃ 25 ppm), P₁₁ (KNO₃ 70% and GA₃ 50 ppm), P₁₂ (KNO₃ 80% and GA₃ 75 ppm), P₁₃ (H₂SO₄ 60% and GA₃ 25 ppm), P₁₄ (H₂SO₄ 70% and GA₃ 50 ppm), P₁₅ (KNO₃ 60% and GA₃ 75). Parameters observed were germination, maximum growth potential, plant height, 

number of leaves, leaf length, and leaf width. Based on the results of the DMRT test at 5% level, it showed that each treatment had an effect on the chemical scarification treatment showing a significant effect on germination, maximum growth potential, plant height, number of leaves, leaf length, and leaf width. However, it did not have a significant effect on the number of leaves at 12 WAP, leaf width at 11 and 12 WAP. Keywords: Plant Height, Leaves, Leaf Width
