“…Relative bloom date of pollenizers is im portant because bloom periods must overlap with those of commercial apple cultivars. Y ear-to-year variability in dates of flowering and in the relative flowering periods of dif ferent cultivars has been reported (2). In the studies reported here, bloom periods started 1 to 14 days earlier in 1983 than in 1982; in 1984 they were 3 to 8 days later than in 1983 (Table 1).…”

Data on flower characteristics and honey bee (Apis mellifera L.) foraging behavior were collected on 34 ornamental crabapple and five apple cultivars. Honey bees showed a strong fidelity to foraging on either non-white or white flowers. Nectar reward had little or no correlation to this behavior. Reflectance readings in a blue range (at 436 nm) were more closely correlated with flower-color categories than ultraviolet reflectance. Considering bee behavior and bloom timing, ‘Manchurian’, ‘Snowdrift’, and ‘Golden Hornet’ are potential ornamental crabapple pollenizers for ‘Delicious’ under Pacific Northwest conditions.

“…Many factors affect the speed at which pollen tubes grow in styles, such as soil fertility and fertilization methods (Williams, 1965), flowering dates (Church and Williams, 1983), temperature and relative humidity (Williams, et al, 1984) and sexual compatibility (Williams, et al, 1984). Spiegel-Roy andAlston, 1982, andMaklad et al, 2011).…”

T HE experiments were performed using (Nour, Fedela, Spinosa clementines, Kishu seedless, Balady, and Seedless mandarins) to determine the compatibility or incompatibility as related to the number of seeds per fruit and the genetic relation between them. For two consecutive seasons (2020 and 2021), the growth of the pollen tube in the styles following self-pollination has been analyzed using a fluorescence microscope to detect incompatibility properties. According to Nour and Fedela clementine cultivars are highly incompatible, while the other four cultivars are incompatible. After receiving pollen, Nour and Fedela clementines had very low pollen tubes that reached style. On the other hand, the highest rate was in the other four cultivars. The DNA of the six cultivars of mandarin and clementine investigated in this study was very similar. Balady mandarin and seedless mandarin appear to have very high similarities, while Fedela clementine and seedless mandarin appear to be very low. RAPD-PCR showed a specific molecule related to incompatibility such as (A-18) RAPD primer, at MW 361 bp. linked to the incompatibility of Nour and Fedela clementine c.vs.

“…This increases the efficiency of fieldwork and reduces working expenses. Thus, crab apples have been planted as pollinizers in single-cultivar apple orchards worldwide since the 1960s (Church et al 1983;Gothard 1994;Paek 1977;Way and Paek 1976;Williams 1967Williams , 1970Williams and Church 1983). They have been also selected (Kim et al 1979) and bred (Ha and Shim 1995), when their blooming times are similar to those of major apple cultivars in Korea.…”

Crab apple cultivars, 'Maypole', 'Tuscan', and 'Manchurian', were evaluated as potential pollinizers of major apple cultivars, 'Fuji', 'Hongro', and 'Tsugaru', cultivated in high-density apple orchard systems. Numerous cultivar characteristics, including blooming time, pollen germination, fruit set, disease and pest resistance, and selfincompatibility, were examined. The blooming times of both 'Maypole' and 'Tuscan' ranged from April 19 to May 5, which was 2-4 days earlier than those of the major commercial apple cultivars. PCR analysis did not reveal the presence of any of the S-alleles (S1, S3, S7, or S9) identified in major commercial apple cultivars. In addition, the percentage of the fruit set was high after trees were artificially fertilized with crab apple pollen. Artificially cross-pollinated fruits were of similar or higher quality than open-pollinated fruits. They also demonstrated resistance to apple blotch, sooty blotch, and fly speck. The results indicate that the two crab apples, 'Maypole' and 'Tuscan' would be potential candidates for pollinizers of major apple cultivars in Korea. Use of the pollen of these crap apples in commercial production will improve fruit quality and promote sustainable and robust fruit production.
