Book excerpt: Maturation rates of monogerm sugar beet seed grown in Western Oregon were measured quantitatively to determine attainment of maximum seed development and germination. Seed was collected at various intervals after anthesis from two hybrid varieties representing the extremes in resistance (hard bolting) and susceptibility (easy bolting) to seedstalk development. The effects of harvesting procedures on seed development and germination were compared at the various stages of maturity using simulated direct and windrow methods. Maturity as determined by maximum germination and dry seed weight occurred at 40, 43 and 45 days after anthesis for the three years studied. Heat units accumulated from anthesis to maturity remained constant for all three years, even though 1965 was much warmer. It was concluded that the seed on sugar beet plants should be mature after 900 heat units are attained or 45 days after peak anthesis. The primary factor lowering the germination potential of mature seed was the occurrence of underdeveloped seeds, Chemical inhibitors in the sugar beet fruits as measured by firm ungerminated seeds may also reduce the germination for seed collected prior to maturity. Some seeds were capable of germination 20 days after anthesis. Plants and seeds of the hard bolting variety remained green throughout the maturation period, whereas easy bolting plants reached senesence and shattered. Plant appearance and percent moisture content were not found to be reliable indicators of sugar beet seed maturity. Maximum germination and dry seed weight were attained at nearly the same levels regardless of harvesting method used. Sugar beets cut prematurely continued seed development while drying on the windrowed plant, but also contained more substances inhibitory to germination. It was determined that germination, dry seed weight, heat unit accumulation and days from anthesis to maturity could all be used to estimate the optimum stage to harvest sugar beets for seed.

This book was released on 1969 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: The influence of several fertilizer elements on the occurrence of underdeveloped seeds in monogerm sugar beets (Beta vulgaris L.) was studied. Lime (CaCO3), nitrogen, phosphorus and potassium fertilizer applications were made to sugar beet seed plots at two locations in the Willamette Valley, Oregon. Seed produced from each treatment was examined by radiography to determine the percentage of fruits containing underdeveloped seeds. Underdeveloped seeds include those which are completely absent from the fruit locule and those which are only partially developed. High nitrogen fertilization negatively influenced seed development, causing an increase in the occurrence of underdeveloped seeds. A larger difference in underdeveloped seeds was noted, however, between the two experimental locations. Lime, phosphorus and potassium applications had no apparent influence on seed development. Experimental locations and nitrogen fertilizer levels influenced the concentrations of several nutrient elements in the sugar beet petioles. But no association was apparent between plant nutritional status and the occurrence of underdeveloped seeds. It was concluded that inadequate or imbalanced fertilizer applications were not the primary factors impeding sugar beet seed development. Although excess nitrogen fertilization was detrimental to seed development, it accounted for only a fraction of the total underdeveloped seeds obtained.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Sugar Beet: Culture, Seed Development, Manufacture, and Statistics The mean summer temperature of these localities is about the same, but the continuation of a semisummer temperature through the winter in southern California greatly favors the growth and manufacture of the beets. In northern Nebraska and South Dakota the beets, which are to be manufactured during the winter time, have to be protected by expensive silos. In southern California and other places similarly situ ated the beets can be protected without any covering, or at most with only a slight covering of leaves or straw. The season for planting in a mild climate is also longer. For instance, in southern California plant-a ing can commence as early as January and continue till June, thus giv ing a beet crop coming continuously into maturity from the 1st of August to the lst of December. In other. Localities the planting must be accomplished in a short time, say from the l0th of May till the 1st of June. Before the first of these dates the ground will be too cold for planting and after the second the season will be. So late as to prevent the maturity of the beets before frost. When the field is properly plowed and subsoiled in the late autumn the farmer will be able to take advantage of the first favorable opportunity in the spring to pre pare the surface of the soil and plant the seed.
