The integrate effect of seed soaking in aqueous plant extracts and ascorbic acid on germination and seedling characters of rice grains under salinity stress [electronic resource]

In the recent years using non-traditional sources such as aqueous extracts plant and ascorbic acid are considered as one of the challenges
for enhancing germination character and seedling parameters of rice grains. Thus, a laboratory experiment was conducted to study the integrate
effect of four plant extracts i.e. turmeric (Curcuma longa), sorrel (Rumexvesicarius), grapes (Vitisvinifera), and roselle (Hibiscus sabdariffa)
in comparison with ascorbic acid (ASA) on germination characters and seedling parameters of rice under salinity stress, using Randomized
Complete Block Design (RCBD) with four replications. Data revealed that there was a noticeable improvement in germination percentage and
seedling vigor index as compared to control treatments treatment due to grains soaking technique. In general, plant tested extracts and
ascorbic acid improved tested criteria in varying degrees as well as improvement was more pronounced in the absence of salinity. The water
extract of roselle ranked the first in improving the tested measurements and recorded the maximum values 89.4 and 67.2%; 5.8 and 4.8 cm; 9.08
and 8.30 cm; 14.88 and 13.1 cm; 1330.2 and 880.3; 294.6 and 284.2 mg; 186.8 and 181.0 mg; 37.6 and 36.8 mg; 27.4 and 26.4 mg of germination
percentage, shoot length, root length, seedling length, seedling vigor index, shoot fresh, root fresh, shoot dry and root dry weights,
respectively in the absence or presence of salinity. While control and ASA treatments recorded the lowest values in this context under
salinity stress.
