The pollen tube responses of four hazelnut genotypes to low (4 °C) and high (30 °C) temperature stress were determined. Pollen tubes stressed by 4 °C and 30 °C showed a reduction in both germination rate and tube length when compared to control (
One of the most substantial molecules for pollen germination and tube growth are polyamines. Putrescine is the most abundant polyamine and the molecule from which spermine and spermidine originate. In this study, the effects of different exogenous pu
