本试验选择茄科的茄子、番茄和辣椒各3个品种，于1993年—1995年进行了活力测定的研究。结果表明：控制劣变测定法、盆栽幼苗检验法和发芽测定法在测定茄科3种作物的种子活力水平、判断种子的耐藏性方面是行之有效的方法；四唑（TTC）定量法、电导率测定法也可测定3种作物种子的活力水平，但不能反映种子个体活力水平，只能反映种子群体的活力水平。此外，本试验总结出了茄科的茄子、番茄和辣椒种子在控制劣变测定种子活力时所要求的特定含水量，分别为22．0％、21．0％和19．0％。
In this experiment, three varieties of solanaceous eggplant, tomato and pepper were selected, and the vitality determination was conducted from 1993 to 1995. The results showed that it was an effective method to determine the seed vigor level of three Solanaceae cultivars, and to determine the seed storage resistance by the methods of controlling deteriorated test, pot seedling test and germination test. The tetrazolium (TTC) Conductivity assay can also measure the vitality level of three kinds of crop seeds, but can not reflect the seed individual vitality level, only reflect the seed population vitality level. In addition, the specific moisture content of solanaceous eggplant, tomato and pepper seeds in controlling the seed vigor of deteriorated seeds were summarized in this experiment, which were 22.0%, 21.0% and 19.0% respectively.
