Effect of Pollen Parent on Pollen Tube Growth in Hass Avocado

This report supplies more information on the pollen-stigma intercompatibility reported on last year. Flowers of the cultivars Hass (A and E trees) and Ettinger were used as female parents and the cultivars Hass (A and E trees), Ettinger and Fuerte (A and E trees) were used as pollen parents for in vitro pollination experiments. As in the previous report, Ettinger as a pollen donor outperformed the other pollen parents, while Hass (A) was the best female parent. This means that if these results could be extrapolated to an orchard situation, Hass orchards interplanted with Ettinger should give higher percentage fruit set than pure Hass orchards. OPSOMMINC Hierdie verslag gee meer inligting oor stuifmeel-stempel verenigbaarheid waaroor daar verlede jaar verslag gelewer is. Blomme van die kultivars Hass (A en E borne) en Ettinger is as vroulike ouers gebruik, terwyl die kultivars Hass (A en E borne), Ettinger en Fuerte (A en E borne) as stuifmeelouers vir die in vitro bestuiwingseksperimente gebruik is. Soos in die vorige verslag was Ettinger die beste stuifmeelouer, terwyl Hass (A) die beste vroulike ouer was. Dit beteken dat indien die resudate na 'n boordsituasie geekstrapoleer kon word, Hass boorde wat met Ettinger gemeng is, beter vrugset behoort te lewer as suiwer Hass boorde.
