Excerpt from Plum Pollination
The yield records for these trees which are available for the years 1915, 1916, and 1917, show some further interesting facts. The first three varieties, which as a rule are the first to blossom each spring, show a comparatively low yield record. Combination yielded at the average rate of 83, 24, and 20 pounds per tree for the three years, giving an average of 42 pounds per tree resulting from a set of per cent. Kelsey gave a consistent average yield of 46, and 30 pounds, or a total average of 38.1'pounds for three years from an average set of 9 per cent. No great difference in yield followed in 1917 as the result of the low percentage of set. Satsuma produced an average yield per tree of and 60 pounds, or a total average of for the years 1915 and 1917. These yields resulted from an average normal set of per cent. The foregoing varieties blossom very early and the yields thus far can only be considered fair from a commercial point of view.

Paperback. Zustand: New. Print on Demand. This book delves into the world of plum pollination, examining the pollination requirements of various Japanese and European plum varieties to help growers achieve optimal fruit set. The author conducted pollination experiments over several years, observing the natural fruit set of different varieties and performing controlled pollinations. The results revealed that most Japanese plum varieties require cross-pollination, with only one variety, Climax, being self-fertile. Among the European varieties, Clyman and Tragedy were found to be self-sterile, while Yellow Egg and Pond showed some self-fertility. The book also highlights the importance of honey bees as pollinators and emphasizes the positive impact they have on fruit set, even for self-fertile varieties. The author discusses the cross-pollination compatibility among the different varieties, providing valuable information for growers to make informed decisions about interplanting compatible varieties to ensure successful fruit production. Overall, this book offers practical insights and scientific data on plum pollination, guiding growers towards effective pollination practices that optimize fruit yields and ensure the continued success of their plum orchards.
