Assessment of pollen morphology, viability and germination in subtropical plum (Prunus salicina Lindl.) grown under Tarai region of Uttarakhand

Abstract

The present investigation was carried out at Horticultural Research Centre (HRC), Patharchatta, GBPUAT Satluj Purple and Kala Amritsari. The pollen morphology (polar length and equatorial diameter) was measured through scanning electron microscope (SEM), while the pollen viability and germination were determined by acetocarmine and sucrose solution test, respectively. The results demonstrated that polar length and equatorial diameter was more in Kala Amritsari, while Satluj Purple was smaller in size; however, the polar/equatorial diameter (P/E) ratio was more under Satluj Purple. Moreover, the pollen viability and germination were higher in Satluj Purple as compared to Kala Amritsari.
