Abstract

Among the species of weeds with early emergence in spring is Lamium purpureum L. The plant is observed by its appearance in the form of small hearths, with relatively high densities, in addition to and in the areas cultivated with wheat. On the one hand, there was an obvious spread in agricultural areas, and on the other hand, a certain culinary and medicinal interest increased. Its spread occurs through the relatively high number of seeds it produces and their persistence in the soil. Morphological characters have shown a continuous evolution, depending on the ecotype existing at a given time. Thus, the average plant measured 13 cm in height and weighed 0.12 g of dry matter. One plant had on average 35 top-like fruit formations, and the number of nuts on a plant was 28. The nuts were 1.8 mm long and 0.8 mm thick. and the mass of one thousand walnuts was at the level of the whole experiment of 0.57 g. Significant positive correlations were obtained between the height of the plants with their weight, with the number of fruit formations and with the number of seeds/ nuts. Negative correlations were between the length of the nuts and the other characters. The determinations performed showed that the weed also adapted to the current climatic conditions in the agricultural field, with the increase of the fruiting of the plants.
紫叶草某些形态特征的变异
在春季出苗期较早的杂草品种中,有紫叶草(Lamium purpureum L.)。除了小麦种植区外,在小麦种植区,这种植物的外观呈小炉状,密度相对较高。一方面,在农业地区有明显的传播,另一方面,烹饪和药用的兴趣增加了。它的传播是通过它产生的相对较多的种子和它们在土壤中的持久性来实现的。形态特征表现出连续的进化,这取决于在给定时间存在的生态型。因此,平均植株高13厘米,干物质重0.12克。一株植物平均有35个顶状果实,一株植物上的坚果数量为28个。螺母长1.8 mm,厚0.8 mm。千个核桃的质量在整个实验0.57 g的水平。株高与株重、果实形成数和种子/坚果数呈显著正相关。果实长度与其他性状呈负相关。测定结果表明,该杂草还适应了当前农业领域的气候条件,随着植物结果量的增加。
