Abstract:
Two experiments on gladiolus were conducted at BARI, Gazipur, Bangladesh during
October 2013 to June 2014. First experiment includes performance of ten gladiolus
genotypes in respect of growth, yield and yield contributing characters to select
promising line

=4% sucrose + 200 ppm 8-HQS +25 ppm citric acid and T
= Control. A
synergized effect of 3 % sucrose + 200 ppm HQS + 25 ppm citric acid proved
effective in maintaining quality and increasing vase life of gladiolus up to 12 days.
