Germination of Cassia fistula L. Seeds by Mechanical Stress

The effect of mechanical stress in presence of different kinds of chemical media on seed germination, percentage of germination and rate of imbibition in seeds of Cassia fistula L. have been studied. A unique germination percentage of seedlings free-from fungus attack were observed in cracked and punctured seeds. Modifications raised by this stress in seeds enhances quick germination in presence of suitable moisture media. To make comparative study between the rate of imbibition and percentage of germination and to know the susceptibility of seeds towards fungal attack, heating and roasting in addition to cracking and puncturing, were applied and discussed.
