Nineteen locally selected potato lines were screened for water stress
tolerance by measuring the growth parameters in vitro. The stress was achieved
by adding 4% of sorbitol to the growth medium. Plant height and diameter,
leaf area, number, lengt
h and diameter of roots and plant fresh and dry weight
were measured. The results showed a difference in the response of the studied
lines to water stress, cluster analysis, based on the sum of all growth
parameters relative values of the lines showed that the lines were divided into
three groups according to water stress tolerance: The tolerant group, the
moderate tolerant group and the sensitive group. The results indicated the
possibility to use the in vitro method to screen the potato lines for water stress
tolerance.
Sweeteners are used as alternatives of Sugar because of their slow
absorption and incomplete metabolism in human body, which are positively
destinies in setting free small amount of calorie.
This research presents the influence of ultrasonic on th
e sorbitol synthesis,
starting from Glucose by implementing hydrogenation using Lithium
Aluminum Hydride. The result we have reached by using the ultrasonic as
compared with mechanical mixing or other method have lead us to two
conclusions:
The first was that we have obtained almost the same quantity of the sorbitol.
The second was that by using ultrasonic, micelles of colloid Aluminum
hydroxide were accumulated. This accumulation resulted in an easy separation
by purification, which eventually lead to a super pure sorbitol solution.
We hope that these results will be useful for the Crystallography science.
