Abstract:The combining abilities, heritability, correlation, aggression, and path for parthenocarpy were
analyzed according to 10 hybrid CIOSS~ made between 3 parthenocarpic lines and 2 non—parthenocarpic lines of
eggplan t with half mating design.The results showed that the heredity of parthenocarpy was not correspondent with
the additive-dominant mode1. Parthenocarpy was ma ybe controled by a group of recessive genes as wel as
influenced by epitasis efect.

利用 HI~ 250型 (哈尔滨产 )人工气候箱,对 5份类番茄茄 (Solarium lyeopersieoides)、1份多毛番茄 (己.hirsutum)
和 1份普通番茄 (己.esculentum)材料 (6~7片真叶)进
行 6~C/2℃ (昼/夜)和25℃/15℃ (作无逆境对照)处理
72 h,光周期 12 h(昼 12 h/夜 12 h),每处理 6株,3次
重复。然后用 日本产 Mc26型电导仪测定电导率。以相对
电解质渗出率和细胞膜伤害率衡量材料的耐冷性。细胞
膜伤害率 (%)= (处理电导率值 一对照电导率值)/
(处理煮沸后总电导率值 一对照电导率值)×100。
测定结果 (表 1)表明,7份材料经 6~C/2~C胁迫后,
相对电解质渗出率介于 9.32% ~15.70%,并有 UC82B>
1136126>S.1ycopersicoides的趋势;25℃/15℃处理各材料
间虽有差异但无规律。6℃/2℃胁迫下细胞膜伤害率介于
3.6l% 一l0.12%,除 LA2730、I_A2951和 I_06126 间无显著
差异外,其他材料间差异极显著 ,并有 UC82B>1136126
>S.1ycopersicoides的趋势。可见 ,类番茄茄表现 出比番
茄属中耐冷性较强的多毛番茄还耐低温。5份类番茄茄
材料在低温胁迫下细胞膜的伤害率也存在 明显差异,因
此 ,用类番茄茄改良番茄耐冷时应注意材料间的差异。
