Abstract

In order to determine the content of different biochemical components in sweet potato tubers under the conditions of sandy soils from D?buleni, the following varieties were studied: Yulmi, Juhwangmi, Hayanmi, KSP 1, KSC 1, grown in transparent mulch culture, in the first decade of May, in the climatic conditions of the period, 2015-2017. All varieties studied showed a total dry matter content of over 30% and the highest content was determined for KSC1 (38.87%). Also, the results obtained with respect to the content of soluble carbohydrates, starch and C vitamin are similar to those in the literature, the differences being due to the studied genotypes and the climatic conditions in the culture area. The determinations made show that the highest total dry matter content was recorded at 110 days after planting, 38.41% of the varieties average and, depending on the variety, Yulmi showed the highest content (41.52% ). The maximum starch content was determined at 100 days after planting, with an average varieties of 13.53%. The highest starch content was determined in the Juhwangmi (14.43%) and KSP1 (14.22%) varieties. As for the content of C vitamin, it showed the highest values in all varieties to 100 days after planting and then begins to diminish. Depending on the years of study, the best results were determined in 2016. The very high temperatures in the summer of 2017, with maximum over 40 В°C in several days, along with the lack of rainfall, had a negative impact on the accumulation of biochemical components studied in tubers.
