用标准方法研究了七种植物种子的发芽势。 不同的向日葵基因型(5个杂交种和2个细胞质雄性 不育雌性品系)在大田和蔬菜作物研究所培育 在诺维萨德。种子用杀菌剂苯菌胺、甲霜灵和 氟虫腈及其杀虫剂甲氧西林和吡虫啉，并保存一年 在储藏室待了一年。方差分析表明，有 不同品种、不同化学处理间差异极显著 储存期。对于所有人来说，也记录了非常显著的差异 所研究的因素之间的相互作用。平均而言，最高的 杂交种H2发芽势最高，达93.45%，发芽势最大 参数的值极显著地高于其他 基因分型，杂交种H1除外。此外，每一种混血儿都有很高的 发芽势明显高于这两个品系中的任何一个，并且 杂交种之间的差异非常显著。看着 在化学处理中，对照的发芽势最高 极显著利润率(80.39%)。观察到的差异最大的是 与杀虫剂处理的关系(5.48%和9.56%)。这些 处理的发芽势极显著地低于 涉及杀菌剂的。发芽势在前九个月有所增加 几个月的储存期，峰值为81.29%。在那之后，大幅下降到 储存12个月后68.94%。不同存储之间的差异 除了6到9岁之间的时间段外，其他时间段都非常重要 几个月的储存时间，这在统计上并不显著。
Using the standard method, we studied the germination energy of seed of seven different sunflower genotypes (five hybrids and two cytoplasmically male sterile female lines) developed at the Institute of Field and Vegetable Crops in Novi Sad. The seed was treated with the fungicides benomil, metalaxyl and fludioxonil and the insecticides thiamethoxam and imidacloprid and kept for a year in a storage facility. Analysis of variance showed that there were highly significant differences among the genotypes, chemical treatments, and storage periods. Highly significant differences were also recorded for all the interactions among the factors studied. On average, the highest germination energy was found in the hybrid H2 (93.45%), whose values of this parameter were highly significantly higher than those of the rest of the genotypes, except for the hybrid H1. Also, each of the hybrids had highly significantly higher germination energy than either of the two lines, and the differences among the hybrids themselves were highly significant. Looking at the chemical treatments, the control had the highest germination energy by a highly significant margin (80.39%). The largest difference was observed in relation to the treatments with insecticides (5.48 and 9.56%). These treatments had highly significantly lower values of germination energy than those involving fungicides. Germination energy increased in the first nine months of storage, peaking at 81.29%. After that, there was a sharp drop to 68.94% after 12 months of storing. Differences among the different storage periods were all highly significant except for that between six and nine months of storage, which was not statistically significant.
