“…Many years ago, Swingle (1928) proposed that hormones produced by the seeds are responsible for the changes. Pollinizer effects on some traits were previously demonstrated in almond (Garc ıa-Gusano et al 2005;Gonz alez et al 2005;Sanchez-Perez et al 2012), apple (Ruth & Williams 1983;T oth et al 2005;Bodor et al 2008), blueberry (Gupton 1997;da Silveira et al 2011), chestnut (McKay & Crane 1939, cucumber (Olfati et al 2010), date palm (Swingle 1928;Muhtaseb & Ghanim 2006), grapefruit (Burger 1985), guava (Usman et al 2013), litchi (Degani et al 1995), loquat (Xu et al 2007), pear (Tufts & Hansen 1933;Nyeki 1972), pistachio (Crane & Iwakiri 1980), pecan (Marquard 1988), olive (Farinelli et al 2012), sour cherry (Ansari et al 2010), walnut (Golzari et al 2010) and watermelon (Freeman et al 2007).…”

Literature investigations indicate that the grapes have quite complex fertilisation biology. This complexity necessitates extensive investigations to obtain reliable knowledge for both well-organised hybridisation studies and maximising grape yield. Therefore, this study was conducted to investigate the influences of self-, free- and cross-pollination on berry and seed characteristics in grape. Five different pollination treatments were applied to 'Narince', the most widely known and popular white wine grape in Turkey. Pollen tests indicated that all the cultivars had satisfactory in vitro pollen viability percentages. Free-pollination produced a significantly higher percentage berry set. Among the pollinizers, the use of pollen of 'Thompson Seedless' and 'Cardinal' varieties resulted in higher berry set percentage in 'Narince'. The free-pollination was also superior in giving the highest weight, length and width of the berry, as well as number of seeds per berry. These findings revealed that there were strong xenial and metaxenial effects in the studied grape cultivars. Among the pollinizer cultivars, the most effective pollinator was 'Thompson Seedless'. Hence, for better berry set and quality, the use of 'Thompson Seedless' as a pollinizer may be an attractive option in both grape production and breeding studies.

“…Similar results were observed by Kodad et al (2009) in almonds and Samocha et al (2014) in Jatropha curcas L. Previous studies indicated that some fruit chemical compositions in other species could also be influenced by different pollen sources. The pollen source affected the total soluble solids of the fruit in date palms (Phoenix dactylifera L.) (Rezazadeh et al, 2013) and the amygdalin content in almonds (Sanchez-Perez et al, 2012). The variation among pollen sources in oil composition could be contributed by its own embryo, which is affected by both the mother and father genotypes (Kodad et al, 2009).…”

The effects of different pollen sources on fruit and seed characteristics of Paeonia ostii ‘Feng Dan’ were investigated using analysis of three different pollination treatments and pollen sources from fifteen cultivars in two successive years. The results showed that self-pollination decreased fruit setting, the number of seeds per fruit, seed volume, seed and kernel weights, and the linoleic acid (LA) concentration in the seed oil, but increased the concentration of oleic acid (OA) compared with cross-pollination. Among those pollen donors, P. suffruticosa ‘Yinhong Qiaodui’ produced the highest fruit set (87.5%); the lowest fruit set was obtained with P. suffruticosa ‘Mo Run Jue Lun’ (44.33%). The most seeds per fruit were achieved by P. suffruticosa ‘Mochi Jin Hui’. P. suffruticosa ‘Dahong Baozhu’ produced the largest fruit, which contained larger and heaviest seeds. The oil extraction ratio (26% to 31.6%) and the concentration of three major unsaturated fatty acids (UFAs) in seed oil also significantly differed among pollen sources. The content of OA, LA, and α-linolenic acid (ALA) ranged from 13.82 to 24.79, 12.09 to 21.84, and 23.50 to 38.64 g/100 g crude oil, respectively. Overall, pollen source has clear effects on seed yield and even on fatty acid (FA) composition of seed oil in tree peony.

“…The influence of pollen on the maternal tissue of fruits has been shown in many plants including fruit trees and several horticultural crops (Riazi et al, 1995;Sanchez et al, 2012 ;Rezazadeh et al, 2013 ;Steven et al, 2019). This recent study, with four different pollination treatments applied to 11 argane genotypes revealed the differences between open-pollination and cross-pollination for most fruit traits (size, color, shape, time of fruit maturity), suggest the influence of the pollinizer (effect of source pollen) on fruit size and female parent effects in shape, time of fruit ripe.…”

During the breeding program studies, the pollen donor parents (pollinizers) were observed to be characterized by a strong flowering rate and very low fruit set, even after hand pollination. Then the notion of pollinizers in the argane species was born, first mentioned, checked, documented and confirmed like other conventional tree species. Since the argane tree is completely self-incompatible, the presence of compatible pollinizers is necessary for the fruit set. Indeed, pollinizers need to be selected accurately based on the synchronization of bloom periods and compatibility to receiver trees (female). The pollinizer is essential in any breeding program and for new orchard plantations. The current study was conducted on 13 argane genotypes including two pollinizers. The flowering period, bloom phenology, floral structure and fruit set of crossed genotypes were monitored, illustrated and a season phenogram was established. The pollen viability and germination were also evaluated. In order to test compatibility, the hand pollination using two selected pollinizer pollens was compared to open pollination. Then, the compatibility system was monitored and evaluated through analysis of crossing diallel programs and through the index of self-incompatibility. The flowering periods are genotype depending and one to three blooms have been observed during the two years study (2018-2019) and the argane tree is a tristylous species (Mesostylous, brevistylous and longistylous flowers). The in vitro tests showed that the pollen originated from crossed genotypes were viable and able to germinate. The cross-compatibility rate depends on cross associations and it varies from 39 to 84 %. In fact, this study showed that the effect of pollen-parent (xenia) occurs in all fruit components of argane tree. It was observed, for the first time, that both compatible pollinizers and xenic effects of pollen on argane fruit have occurred. Artificial pollination is currently feasible for breeding programs and the screening of elite genotypes. Then the selected pollinizer is quite required for the development of argane tree cropping.
