S. Siddiqui et al., SOIL-SALINITY EFFECT ON SOLUBLE SACCHARIDES, PHENOL, FATTY-ACID AND MINERAL CONTENTS, AND RESPIRATION RATE OF GARLIC CULTIVARS, Biologia plantarum, 38(4), 1996, pp. 611-615
The effect of salinity on contents of water, soluble saccharides, phen
ols, minerals and on respiration rate in bulbs of five garlic (Allium
sativum L.) cultivars differing in salinity tolerance was determined.
Cultivar HG-6 was found to be the most tolerant followed by cvs. G-l a
nd G-42, and cv. Aru the least tolerant to salinity. The cultivars whi
ch were tolerant showed lesser reduction in water content of the bulbs
by salinity. Initial contents of phenolic compounds and sulphur were
comparatively low in salinity tolerant cultivars but they increased un
der high salinity levels whereas reverse was found in salt sensitive c
ultivars. The fatty acids profile did not show significant changes und
er saline conditions. Contents of K and Ca were reduced, content of Na
was increased and there were no changes in the contents of N, Mn, Cy
Zn and Fe. The changes in soluble saccharides content and respiration
rate were not found to be associated with the salinity tolerance.
