“…In addition to preventing self‐fertilization, SI can also act as a barrier between individuals sharing the same SI phenotype and, thus, influences pollen‐mediated gene flow by limiting compatible matings (Bateman, ). Moreover, by interfering with plant production and breeding, SI is a major obstacle for constant fruit production in crop species (Sassa, ), as well as for the breeding of new cultivars and the development of inbred lines (Matsumoto, ). Deciphering the SI system of plants is therefore of great interest in agronomy, horticulture, and forestry.…”

Self‐incompatibility (SI) is the main mechanism that favors outcrossing in plants. By limiting compatible matings, SI interferes in fruit production and breeding of new cultivars. In the Oleeae tribe (Oleaceae), an unusual diallelic SI system (DSI) has been proposed for three distantly related species including the olive (Olea europaea), but empirical evidence has remained controversial for this latter. The olive domestication is a complex process with multiple origins. As a consequence, the mixing of S‐alleles from two distinct taxa, the possible artificial selection of self‐compatible mutants and the large phenological variation of blooming may constitute obstacles for deciphering SI in olive. Here, we investigate cross‐genotype compatibilities in the Saharan wild olive (O. e. subsp. laperrinei). As this taxon was geographically isolated for thousands of years, SI should not be affected by human selection. A population of 37 mature individuals maintained in a collection was investigated. Several embryos per mother were genotyped with microsatellites in order to identify compatible fathers that contributed to fertilization. While the pollination was limited by distance inside the collection, our results strongly support the DSI hypothesis, and all individuals were assigned to two incompatibility groups (G1 and G2). No self‐fertilization was observed in our conditions. In contrast, crosses between full or half siblings were frequent (ca. 45%), which is likely due to a nonrandom assortment of related trees in the collection. Finally, implications of our results for orchard management and the conservation of olive genetic resources are discussed.

“…Under conditions of cold irregularity during the winter period, typical of the southern region of Brazil, the low synchronization of flowering of the main cultivars and their respective pollinators is frequent, leading to low fructification and production irregularity (HAWERROTH et al, 2011;GARRAT et al, 2014;MATSUMOTO, 2014;QUINET et al, 2016). In addition, low yields can occur under conditions adverse to pollination, such as occurrence of rainfall during flowering, deficiency of pollinating insects and when flowering intensity is reduced.…”

Effect of Thidiazuron Concentration and Application Period on ‘Royal Gala’ Apple Fruiting and Production

et al. 2017

-'Gala' apple trees have low fruit set in restrictive pollination situations, being an obstacle to the achievement of high production rates in orchards in southern Brazil, which can be minimized by the use of growth regulators. The aim of this study was to evaluate the effect of thidiazuron concentrations in 'Royal Gala' apple fruiting and production, grown in mild winter conditions. The experiment was conducted during the 2011/2012, 2012/2013 and 2013/2014 crop years in Fraiburgo, SC, on 'Royal Gala' apple trees in Marubakaido rootstock M9 with filter. In all evaluation cycles, the experimental design was a randomized block with factorial arrangement (6x2) with six TDZ concentrations and two application forms, with six replicates, and the experimental unit consisting of one plant. The TDZ concentrations of each treatment were applied split into two seasons. The first application was performed on pink bud stage (E2) and the second application was in full bloom stage (F2). The variables evaluated were: fruit set (%), return bloom (%), number and weight of fruits per plant, mean fruit weight (g) and average number of seeds per fruit. Data were submitted to analysis of variance, in which for significant variables by the F test, analysis of contrast and polynomial regression were performed in order to evaluate the response of variables with increasing TDZ concentration. TDZ is effective even at low concentrations, increasing the production and fruit set of 'Gala' apples in the climatic conditions of southern Brazil.

Identification and characterization ofS-RNasegenes in apple rootstock and the diversity ofS-RNasesinMalusspecies

et al. 2016

We isolated and confirmed two S-RNases, denoted as mpS1 and mpS2, from apple rootstock 'Marubakaido' (Malus prunifolia Borkh. Var. ringo Asami). These S-RNases contained and conserved five cysteine residues and two histidine residues, which are essential for RNase activity. The mpS1 showed high similarity to S5 (99.1%) of Malus spectabilis, whereas the mpS2 showed 99.5% nucleotide sequence similarity to S26 of (Malus × domestica) and 99.6% to S35 of (Malus sieversii) when compared with reported S-RNases. In amino acid sequences, the mpS1-RNase was almost similar to the S5-RNase of Malus spectabilis, and the mpS2-RNase was similar to the S35 of Malus sieversii, with only one bp being different from the S26-RNase of Malus × domestica. The 57 S-RNases of Malus species were renamed and rearranged containing the new S-RNases, as mprpS35 (mpS2) and mprpS57 (mpS1), for determining S-genotypes and identifying new alleles from apple species (Malus spp.).
