Plums are affected by a cancerous disease called “Black Knot disease” caused by the fungus Apiosporina morbosa. It affects both Japanese (Prunus salicina) and European plums (Prunus domestica) equally. In order to understand the spread of the disease, histological analysis was performed in two different European plum cultivars (susceptible and tolerant). Light and Scanning Electron Microscope (SEM) analyses confirmed the presence of the growing hyphae in the internal tissues of the susceptible trees. By using stereoscopic analysis with a fluorescence filter, we were able to detect the hyphae in the visible lesion area. At about 2 inches from above and below the knots, no spore or hypha was visible with the light microscope. However, SEM images showed strong evidence that the fungus is capable of migrating to adjacent vessels in the susceptible plum genotype. In fact, at that distance below and above the knots, conidia were detected inside xylem vessels suggesting a systemic movement of the fungus that has not been shown so far. No symptoms were observed in the resistant genotype. Starch granules, vessel occlusions and lipid droplets were the main distinguishable characteristics between susceptible and tolerant varieties.

Abstract A description is provided for Polystigma rubrum. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Prunus domestica, Prunus institia (syn. Prunus domestica subsp. institia), Prunus spinosa. Records on Prunus salicina (e.g. 46, 1510; 52, 1801) have not been verified. DISEASE: Large brightly coloured spots on leaves. GEOGRAPHICAL DISTRIBUTION: Armenia, Austria, Belgium (17, 68), Bulgaria (16, 392), Channel Islands, China, Cyprus, Czechoslovakia, Denmark, Finland, France, Germany, Greece (52, 2856), Hungary, India (60, 6325), Iran, Iraq, Ireland, Italy, Japan (46, 1510), Kazakhstan (61, 1062), Kirghizia (61, 1062), unverified, Korea (52, 1801), unverified), Lebanon (49, 982), Lithuania (42, 308), Moldova (Fatina, 1989), Netherlands (Oudemans, 1897), Poland, Portugal (Sousa da Câmara, 1916), Romania, Russia, Serbia, Spain (7, 407), Sweden, Switzerland, Tadzhikistan (47, 576), Turkey, Ukraine, United Kingdom, Uzbekistan (61, 1062, unverified). TRANSMISSION: Stromata develop throughout late spring and summer on living leaves, producing conidia in summer and autumn, and ascospores from fallen overwintered leaves the following spring. Conidiomata sometimes persist in an apparently viable condition until the ascomata are mature. Transmission is by air-dispersal of ascospores.

Available Information

Japanese plums (P salicina) and cherry plums (P cerasifera) are diploid species, while European plum (P. domestica) cultivars are hexaploids. Most diploid species are self-incompatible while fertility relations of the hexaploid European plums are variable between self-incompatibility and self-compatibility. About twenty S-alleles and six inter-incompatibility groups and one S-haplotype responsible for the self-fruitful phenotype were described in Japanese plum cultivars, but studies on cherry plums and even on the European plum cultivars are severely restricted. This review is focused on the available information obtained from myrobalans and European plums; and discusses recent hypotheses regarding the putative origin of the hexaploid plums, and thereby indicates the possibility of allele flow between different plum species.

Marcadores moleculares têm sido amplamente utilizados nas mais variadas espécies frutíferas para análise de "fingerprinting", para o processo de certificação de material vegetal e como ferramenta auxiliar em programas de melhoramento genético, para acessar a variabilidade genética entre genótipos. Dado a importância da cultura da ameixeira para a região Sul do Brasil, o presente trabalho teve por finalidade contribuir para a caracterização genético-molecular de 17 cultivares. As cultivares foram analisadas com 12 marcadores RAPD, que produziram 187 polimorfismos. O marcador OP A20 foi o mais polimórfico, produzindo 26 perfis diferentes. A análise de agrupamento, realizada com o método UPGMA, produziu um dendrograma que permitiu uma clara separação das cultivares em três grupos, correspondentes às suas respectivas espécies, Prunus salicina, Prunus domestica e Prunus cerasifera. O alto grau de polimorfismo detectado pelos marcadores RAPD confirma o potencial da técnica na análise de "fingerprinting" e sua utilidade na estimativa da variabilidade genética entre cultivares de ameixeira.

Fruit Growing

The worldwide tendency to increase the intensity of fruit growing technologies prefers generally for every fruit species rootstocks with week or mediocre vigour. From this viewpoint, the use of rootstocks for plums are rather unilateral in Hungary, where 95–99% of plum plantations are grafted on mirobalan seedlings (P. cerasifera v. mirobalana). The score of plum rootstocks abroad is much more diversified. The present study summarises the respective knowledge referring to the literature available.
