| Abstract:
The effects of the pollen parent (xenia) on seed and fruit characters are known to occur in several nut crops. For pistachio this phenomenon is under discussion. In this experiment, effects of Pistacia vera, P. atlantica and P. terebinthus pollen on fruit size and weight of two commercially grown cultivars (P. vera cvs. 'Mateur' and 'El Guettar') were tested and compared to an open-pollinated control. For the two cultivars it was concluded that fruits obtained by pollination with P. atlantica pollen, were better than those resulting from pollination by other Pistacia species and a significant difference was noted for some parameters measured. In contrast, no effects of the different pollinators were observed for kernel weight. For 'Mateur' the percentage of blank fruits was lower (6.76%) under open pollination, while for 'El Guettar' the use of P. terebinthus pollen gave the lowest percentage (19.46%). | |
