Postplanting weekly or biweekly applications of metalaxyl at 0.312 mg or 0.600 mg a.i. L−1 soil were as effective as steam sterilization in controlling apple replant disease (ARD) symptoms in greenhouse studies. Growth improvements obtained with metalaxyl suggest that Oomycetes may be involved in ARD in Quebec. In orchard trials plastic mulch, as a cultural treatment, was found to be as effective as methyl bromide, chloropicrin and formalin against ARD; metalaxyl, Vorlex and nitrogen were found to be less effective.Key words: Replant, apple, Malus pumila Mill., Pythium, mulch

Abstract Long-term copper toxicity has been demonstrated in Scenedesmus quadricauda. Upon continuous exposure to copper ions at 250 μg/L, the algae responded by a sharp increase in the synthesis of complexing polypeptides to chelate Cu. Complexing polypeptides gradually decreased, as observed by six sampling tests over 732 h, resembling to a negative exponential curve. This gradual diminution is considered to be a prime mechanism of acclimation or of adaptation to a heavy metal contaminated environment.

Nine years after liming a sandy loam orchard soil to pH 6.0 with calcium hydroxide or dolomitic lime, pH and extractable Ca and Mg were still higher where limed than where unlimed. However, pH had decreased below 5.0 in the limed and N-fertilized plots. Delicious (Malus domestica Borkh.) apple tree nutrition benefited from the two soil amendments. Leaf Mg was increased by dolomite. Leaf Ca was increased by calcium hydroxide. Leaf Mn, although highest in unlimed soils, increased over time for both limed and unlimed soil.

A comparative analysis of the varietal variability of the fruits of 71 varieties of apple trees of Altai selection in terms of biochemical composition, according to generally accepted methods using statistical variation analysis based on long-term research, was carried out. Correlations were revealed between the content of chemical elements depending on other characteristics of the fruit and the period of ripening. The average content of soluble dry matter in fruits is from an average 15.5% in summer varieties to a high 16.2–16.3% in varieties with autumn and winter ripening. On average, the content of total sugars in fruits is high and varies insignificantly from 12.7 to 12.9%, the content of titratable acids in fruits is high – 1.0%. The content of ascorbic acid is higher in fruits of varieties with summer ripening and is 24.0 mg / 100 g, with autumn – 19.6 mg / 100 g, with winter – 22.0 mg / 100 g. As a result of selection for the qualitative improvement of fruits apple trees in Altai revealed a negative correlation of the biochemistry of the fetus, depending on its size for all indicators. Fruits of a significant part of varieties created in Altai have good taste, of which 27 have a sugar-acid index of 15–25. The fruits of the varieties Alpek, Altai Velvet, Altai New Year, Altai ruddy, Altai sweet, Gornoaltayskoe, Zolotaya taiga, Pepinka Altai have a very high sugar content of more than 15%, a high value of the sum of sugars – in fruits of 59 varieties from 10.0 to 14.9%. Varieties with high biochemical characteristics are their sources in breeding for improved biochemical composition of fruits.
