Recent Advances in Production Technology of Major Temperate Fruit Crops (Apple, Pear, Peach, Plum, Apricot, Almond, Cherry and Walnut)

This PowerPoint presentation provides a comprehensive overview of the cultivation and characteristics of two important fruit crops: plums and apricots. It begins by detailing the composition of fruit, specifically focusing on the organic acids found in fruit juice, such as malic, citric, and quinic acid, along with nutritional values per 100 grams of flesh. The presentation then transitions into the training and pruning practices for plum trees, highlighting the differences in systems used in Europe and India, and emphasizing the minimal pruning required for these trees. It discusses the ideal planting conditions for plum trees, including the appropriate age of trees for planting, optimal planting times, spacing, and sunlight requirements.

Propagation methods for plums are also covered, detailing commercial techniques such as budding and grafting, with specific mention of tongue grafting and T-budding. The presentation further explores the characteristics of various rootstocks, categorizing them based on their vigor, salt tolerance, drought resistance, and disease resistance. Following this, the flowering and fruit set stages of plums are discussed, noting the timing of flowering for European and Japanese plums, the abundance of hermaphrodite flowers, and the role of pollinators like honey bees.
