Pollen germination in Robusta coffee
Studies were conducted to find out the differences in pollen germination in Coffea canephora Pierre ex Froehner (S.274 and bulk robusta) in vitro. Sucrose solution at three concentrations viz 10, 20 and 40 were used as media, distilled water being control. The percentage of pollen germination was maximum (68.87) at 10 concentration in S.274 while it was 55.92 at 20 concentration in bulk robusta. Ten per cent sucrose solution from the present study was found to be a good medium for maximum percentage of germination in S.274. The lengt of the pollen tube was found to be maximum in S.274 (190.4¿) at 10 sucrose medium, closely followed by 20 sucrose solution. Increase in tube growth was significantly higher in S.274 than in bulk robusta at 10 and 20 sucrose solution. Earlier work on pollen germination conducted at Central Coffee Research Institute and elsewhere is discussed
