Study on the dynamic change of the starch content in hypocotyles of two Mangrove species

The dynamic change of starch content in hypocotyles of two mangrove species, Kandelia candel and Bruguiera gymnorrhiza,were studied.As the time proceeds,both the total content of the starches and the content of starches per unit weight increased simultaneously.In April when the hypocotyles of Kandelia candel mature,the content of starches in hypocotyles of Kandelia candel could reach as high as 2.63±0.31g in per individual in average,and 24.95%±0.76% in per unit weight,while the content of starches in the viviparous hypocotyles of Bruguiera gymnorrhiza could reach 2.81±0.25g,and 20.07%±0.80% in per unit weight.
