Six trees of each cultivar received six pollination treatments: three cross-pollen sources, self-pollination, bagging and bagging with emasculation. Pollen tube growth, percentage fruit set, fruit weight, seediness, sugar and acid content were assessed in all treatments. Significant xenia effects, including effects on sugar content, were found in all cultivars. `Imperial' was found to be self-incompatible as self-pollen tubes were inhibited in the upper style. This resulted in a lower fruit set in self-pollinated fruits (P<0.01), a very low fruit weight (33–55 g, compared with 92–103 g, P<0.01), and fruits containing few or no seeds. In addition, `Ellenor' and `Murcott' pollen significantly increased sugar content of fruit by between 0.9–1.6% compared with self-pollinated and unpollinated treatments (P<0.05).

Since `Topred' exhibits full self incompatibility, its fruit production is totally dependent on cross pollination. The two commercial pollenizers of `Topred' in Israel are `Golden Delicious' and `Jonathan'. In the study presented here, the potential of these two pollenizers was determined. In two consecutive seasons, it was found that the rate of fruit-set and fruit yield were significantly higher in the rows of `Topred' adjacent to the `Golden Delicious' as compared with the rows adjacent to the `Jonathan'. PCR analysis of the S-alleles, a polymorphic gene locus, determining the outcome of pollination, revealed that `Jonathan' and `Topred' share allele S9. PCR-S-allele analysis of progeny seedlings revealed that in `Jonathan' only S7, the unshared allele, took part in fertilization, whereas both alleles of `Golden Delicious' (S2,S3) participated at equal rates.

In some cases, exogenously applied respiratory inhibitors (NaN3, 2 mM and KCN, 100 mM and 3 mM) were not present in sufficient quantities to inhibit respiration, and yet production of volatiles was inhibited: indicating the action of cytoplasmic enzymes in the conversion of precursors into volatiles after harvest. Post-harvest respiration, whether via normal or alternative pathways, is a requirement for production of volatiles. Production of volatiles concurrent with activation of the alternative pathway may suggest that ATP may not be required. Large buds and open flowers consume three times as much oxygen as smaller buds after harvest: one reason for the reduced amounts of volatiles produced after harvest in small and medium sized buds, and in early stages of flowering.","PeriodicalId":54808,"journal":{"name":"Journal of Horticultural Science & Biotechnology","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"1999-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/14620316.1999.11511134","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"60224404","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

No significant interactions between nitrogen availability and supplementary light on yield, nitrate content, osmotic potential of expressed leaf sap and component osmotica were found. Supplementary light greatly increased plant growth and resulted in earlier harvest. When harvested with similar fresh weights, plant nitrate content was significantly reduced by supplementary light although the effect was slight. The reduced contribution of nitrate to sap osmotic potential at the higher light level was accompanied by a significant increase in the contribution of sucrose.

The present study aimed to determine the optimum harvest time to minimize storage losses. Experiments with two cultivars (Fontana F1 and Panther F1) were performed at an experimental site and on farms for three years. Delaying harvest decreased storage losses which mainly comprised spoilage due to storage diseases. Infections by the two major pathogens, Mycocentrospora acerina and Botrytis cinerea, were reduced towards the end of the harvest period. No further improvement in storability was observed after early October, but storage losses did not increase with a later harvest in most cases. Changes in storability were generally not related to weather conditions at or prior to harvest. Only the continuous frost at the very end of October in one season impaired storage quality.","PeriodicalId":54808,"journal":{"name":"Journal of Horticultural Science & Biotechnology","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"1999-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/14620316.1999.11511141","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"60225214","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
