Compound III, 2-furan-2-yl-[1,3]dioxolane, demonstrated good activity in shortening germination time, improving root growth, and increasing drought and salinity tolerance. In a water medium, the three substituted dioxolanes increased root numbers. Under water-deficit stress all treated seeds germinated by the fifth day, whereas controls did not germinate until after 6.5 days. These dioxolanes increased root number and root length. Compound III was the most outstanding of the three, with an increase of 227% in root number, 234% in root length, and 295% in shoot dry mass. Under salinity stress, these dioxolanes significantly improved growth (promotion of root number and shoot dry mass), although they had no effect on tissue moisture content. Field trials showed that compound III promoted root growth, increased root fresh weight significantly, and maintained a normal yield under water-deficit conditions. It showed low mammalian and environmental toxicity in various toxicologic tests. Results of Salmonella typhimurium reversion assay with and without a S9 mixture and the chromosomal aberration assay revealed that it had no mutagenic potential under experimental conditions.
