Effect of antitranspirants on the germinating seeds of Sorghum vulgare L.

The antitranspirants are helpful for controlling the transpiration rate and internal water balance. In Kolhapur and adjoining area Most widely distributed improved indigenous rabbi variety of Sorghum is Maladandi-35-1 (M-35-1). This variety has been still popular throughout Maharashtra for water stress tolerance capacity. In the present investigation we have tried the effect of two antitranspirants viz. HICO 110 R and Abscisic Acid (ABA) on germination of Sorghum vulgare L. The lower concentration of HICO-110 R (1g/L) showed less inhibition of germination percentage. The root length is stimulated by HICO-110 R, while ABA exhibited inhibitory effect. The root/ shoot ratio represented histographically reveals gradual decline with the advancement of time (fig 3). ABA does not favour seedling growth, however HICO-110 R favour the seedling growth. Sorghum seed germination is reduced due to application of both HICO-110 R & ABA. The ABA showed more inhibitory action than that of HICO-110 R.
