Abstract
Relevance and methods. In some Umbelliferae crops, the ratio of the parameters of the seed (the relative length of the embryo) has a significant effect on the ability of seeds to germinate. We studied 10 coriander samples, which showed significant differences in the degree of severity of the main morphological parameters, including the length of the seed, endosperm and embryo.
Results. The indicators of the hybrid 5/19 and the variety Stimul significantly exceeded the average value of the population in the length of the seed at 1%, and the sample of the local population from Azerbaijan had the lowest indicator at the 5% level of significance. The endosperm length of the hybrid 5/19, the variety Stimul and the sample of the local population of Egypt exceeded the level of the indicator on average in the experiment. According to the length of the embryo, the Nectar variety, hybrid 5/19 and samples from Egypt and Azerbaijan were at the level of the average value for the experiment. The largest embryo (1.063±0.04) was distinguished by the Commander variety. Four samples significantly exceeded, and the hybrid 11/19 were lower than the average value. Depending on the variety, the coefficient of variation of indicators varied for the length of the embryo (13.9-19.1%), the length of the endosperm (16.4-20.4%) and the length of the seed (15.7-22.1%). The maximum value (0.377) of the IZ/E index, which characterizes the ratio of the size of the embryo and endosperm, was observed in the Commander variety. A close correlation was found between the length of the seed and the length of the endosperm, the correlation coefficient varied from r=0.640 in the Stimul variety to r=0.981 in a sample of the local population of Egypt. A weak or medium correlation was observed between the length of the embryo on the one hand and the length of the endosperm (0.026-0.393) and the seed (0.090 – -0.132) on the other. For the IE/S index, which characterizes the ratio of endosperm size to seed size, the limits (0.893-0.988) of variability were significantly lower. The maximum index (0.988) was found in a sample from Egypt.
