The role of the variety in exploiting the biological potential during flax straw processing
https://doi.org/10.26898/0370-8799-2025-6-4
Abstract
The article provides information on the biological potential of new varieties of fiber flax of the FRC BFC selection in terms of fiber content, yield and number of long fibers, the range of variation of values of which is from 26.6 to 37.5%, from 19.1 to 32.5%, from 11.00 to 14.20 the numbers, respectively. According to the results of the control developments of flax straw of various quality carried out in the AO “Vyshnevolotsky Flax Plant” of the Tver region from 2019 to 2023, the maximum degree of use of the biological potential of the varieties based on fiber productivity was determined. It was found that with the range of variation in the section of varieties in terms of long fiber yield from 7.6 to 16.6%, the degree of potential utilization varies from 31.0 to 56.8%. For a long fiber number, this criterion ranges from 70.4 to 90.9%, with the number varying from 10.00 to 11.00. The degree of use of the biological potential according to a complex indicator - long fiber percentage numbers, the change in values of which was from 31.0 to 182.6, ranges from 9.7 to 48.1%. It has been proved that the role of the variety in ensuring an increase in the efficiency of processing flax is significant. The values for the yield of long fiber from a flax fiber having the number 1.00, depending on the variety, differ by 6.9%, in its quality by 2.00 numbers. The range of variation in the values of the same signs (flax straw number 1.75) is 7.5% and 1.00 number. Such differences can lead to a 25% reduction in the cost of fiber products. Despite the low degree of realization of the biological potential according to the percentage of long fiber, varieties with the optimal proportion of long fiber, taking into account its number, have been identified. The ratio of the specific gravity of long and short fiber percentages for the best varieties of fiber flax is in the following proportions: 74 : 26% (Sursky), 73 : 27% (Alexsan drit), 68 : 32% (Visit).
