Features of the manifestation of morphometric parameters of seeds in populations of vegetable chervil (Anthriscus cerefolium (L.) Hoffm)

The morphometric parameters of the internal structure of seeds in seven representatives of the common chervil (Anthriscus cerefolium (L.) Hoffm.) were studied. The variability of the linear dimensions of the seed, endosperm and embryo, the values of the indices Iz/e, Iz/s and Ie/s are shown. The analysis of correlation connections between them is given. The studies were carried out at VNIIO, a branch of the FGBNU FSVC. Seeds of the variety Aromatny (standard) had a length of 7.12±0.146 mm. Significantly smaller seeds had two accessions, variety Ogorodnik (6.56+0.158 mm) and No. 21, which is 8.0 and 27.0% less than standard. Seeds of a significantly larger size, including No. 24 and No. 22, respectively, by 3.0-18.0% higher than control. The endosperm length of the standard was 5.20+0.121 mm. The smallest size of the endosperm was noted in sample No. 21, which is 7.1% less than the control. Three samples significantly exceeded the standard (by 7.5-16.5%) in terms of the length of the endosperm, including samples No. 20 and variety Ogorodnik. The length of the embryo in the Aromatny variety is 1.54+0.119 mm. Samples of variety Ogorodnik and No. 21 had an embryo significantly less than the standard by 14.3 and 10.4%. Significantly larger embryos were found in samples No. 24 and No. 22, which is 17.5-44.2% higher than control. The coefficient of variation (V, %) for the parameter seed length varied from 9.17% to 12.3%, for the endosperm length from 8.35% to 14.6%, and for the embryo from 20.1 to 34.8%. The Izs index varied from 0.195 to 0.266. The Ie/c index varied from 0.707 to 0.930. A close relationship (0.675-0.863) was noted between the length of the seed and the length of the endosperm, with downward deviations to a value of 0.265 in sample No. 21 and Dietichesky variety. The presented information on the example of chervil seeds indicates a significant variability of morphometric parameters. The data obtained can be used for an in-depth characterization of seed quality, substantiation of priming technology.
