This book was released on 1969 with total page 240 pages. Available in PDF, EPUB and Kindle. 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.

This book was released on 1970 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies were conducted on the causes of low germination of monogerm sugarbeet seed grown in western Oregon. Emphasis was placed on the identification and measurement of endogenous inhibitors as related to the germination and vigor. Both qualitative and quantitative analytical methods were applied to examine the organic substances in the aqueous seedball extracts as influenced by environmental factors during maturation. Effects of exogenous factors such as harvest time after anthesis, liming of the soil and post harvest drying temperature on the subsequent germination were examined. Attempts were made to improve germination potential of a given seed lot by pre-germination treatments. Effects of soaking, leaching and drying upon germination were compared and examined. Leaching studies were further expanded to measure the change of inhibitor content at various leaching intervals and to relate concentrations to germination and vigor. Varying concentrations of gibberellic acid (potassium salt) were applied to germinating seed to examine effects on seed dormancy. Five phenolic compounds and oxalic acid as the soluble and insoluble salt were shown to be present in the sugarbeet fruit. Among the five known phenolic substances, ferulic acid was most inhibitory to germination. Oxalic acid at various levels of concentration did not influence germination although oxalic acid did inhibit the seedling growth at relatively low concentrations. Among four sugarbeet seed samples tested, a low germinating lot (variety 4426) was shown to contain the least amount of oxalic acid, however, ferulic acid content of this lot was considerably higher than the others. It was concluded that oxalic acid was not involved in dormancy of the seed samples tested. Among the several pre-germination treatments tested to improve germination potential of the given varieties, complete drying after leaching of seed samples showed the best response. Germination potential of the monogerm varieties used in these studies greatly increased by drying them completely after leaching. Vigor as measured by length of seedlings was markedly improved. Simple leaching did not improve germination. Optimum leaching time for best germination of the varieties tested was from 12 to 20 hours.
