JORGE SUAREZ, Héctor; GONZALEZ MARRERO, Alberto; PEREZ PEREZ, Yosel  y  SUAREZ BENITEZ, Oscar. Influence of hydrothermal treatment time on the percentage of sprouting, cane production and control of seed diseases propagated by cuttings. Ctro. Agr. [online]. 2020, vol.47, n.3, pp. 33-42.  Epub 01-Jul-2020. ISSN 0253-5785.

The work came true for the sake of determining the influence that exercises the passage of time of hydrothermic treatment in the seed reproduced by cuttings in the variables percentages of brotation, production of cane and in disease control, for what refused to compromise an experiment in the Basic Seed Bank (BSB) of Cienfuegos in November 2017. In the study they were once three treatments were evaluated hydrothermic (50,5 ºC 3 hours (Test), 50,5 ºC 2 hours and 51 ºC 1 hour) in five cultivars. The studied variables were percentage from brotation at 60 days of planted, diagnostic for UMELISA in front of the scald foliating, tinction of the vessels of the xylem (diagnosis officially), agricultural performance and its components, at ten elderly months. He used the random block design with three repetitions and came true analysis of variance, simple and bi-factorial, try comparative of stockings by means of Multiple proof of rank with test of Tukey and the Analysis of Conglomerates (Cluster Analysis). The results made an offer that the treatment of 51 ºC surpassed in the percentage of brotation and in the sugarcane production to the two remainders and that there were no differences in the diagnostic for UMELISA. In the diagnosis officially in all the samples they presented more of an 85 % aptitude of the xylem vessels.
