“…Perhaps the variation is due to variable compatibility between cultivars with respect to temperatures and rates of pollen tube growth (Griggs and Iwakiri 1975;Garcia and Egea Ibanez 1979). In any case, there is sufficient evidence (e.g., Table 4, Erickson et al 1977) to suggest that high nut sets obtained through hand pollination may be attainable throughout an orchard by open pollination.…”

“…Several authors have found that from 30% to over 50°/o of almond flowers can produce mature nuts (Kester and Griggs 1959a;Erickson et al 1977;Micke and Kester 1978); yet in commercial orchards percentage set is normally much less and is commonly 5-30% (Tufts 19 19;Griggs 1949;Kester and Griggs 1959a;Gary et al 1976). While an increase in percentage set decreases the size of individual nuts (S. J.…”

During 1978-80, flower emergence was recorded on 12 almond cultivars (Prunus dulcis) at Angle Vale, South Australia. Early flowering cultivars showed a larger annual variation in flowering period (2-3 weeks) than late flowering cultivars (0-2 weeks). In the same period, pollen production ranged from 30 to 122 mg per 100 flowers and in vitro pollen germination ranged from 76.1 to 99.0%. Pollen production and in vitro germination differed significantly between cultivars. Hand-pollination of Nonpareil with pollen from each of eight other cultivars resulted in significantly higher nut set than with open-pollinated or self-pollinated flowers. In contrast to Nonpareil, hand-pollination of Chellaston with pollen from five other cultivars resulted in significantly higher nut set compared with self-pollinated Chellaston but not compared with open-pollinated Chellaston. The potential increase in almond yield due to improved pollination is discussed.
