Abstract


The aim of the research was to find out resistance of the five varieties of chili pepper
to various concentrations of NaCl salt by Germination Test. The research was
conducted in the seed technology laboratory of the Faculty of Agriculture, University
of North Sumatera on December 2011. The research used Randomized Block Design
with two factors and three replication. The first factor was variety, consisting of five
varieties, namely Laris, Mario, TM 007, TM 999, and Hot Star. The second factor was
salt concentration, consisting 4 levels, namely G0(0 ppm), G1 (1000 ppm), G2 (2000
ppm), and G3 (3000 ppm). The parameters observed in this research were germination
percentage, germination rate, percentage of normal and abnormal seedlings,
percentage of dead seeds, seedling fresh weight and seedling height. The results
showed that varieties significantly effected germination rate, percentage of dead
seeds, seedling fresh weight and seedling height. While salt concentration did not
show any significant affect on all parameters. It can be concluded that among the
varieties tested, the Mario variety showed best tolerance to NaCl salt, the least
tolerance was Hot Star.
