Resistance to Colorado potato beetle in a clone of Lycopersicon hirsutum f. hirsutum L. is attributed to the presence of the sesquiterpene zingiberene in the type VI leaf trichomes; however, both day/night temperature regimen and photoperiod affect zingiberene content and trichome density. In short days (SD), zingiberene content per trichome is more than 3-fold greater than in long days. In SD, trichome density per unit leaf surface is 2-fold greater at 25/20 degrees C (day/night) than at either 30/25 degrees C or 20/15 degrees C, thus indirectly influencing zingiberene content per cm(2). In long days, temperature regimen had little effect on either trichome density or zingiberene content, although trichome density was greater than or equal to that in SD.
在 Lycopersicon hirsutum f. hirsutum L. 的一个克隆中，对科罗拉多马铃薯甲虫的抗性归因于第六类型叶毛状体中倍半萜姜黄烯的存在；然而，日/夜温度方案和光周期都会影响姜黄烯的含量和毛状体密度。在短日照（SD）下，每个毛状体的姜黄烯含量比长日照（LD）下高出 3 倍以上。在 SD 下，25/20°C（日/夜）的单位叶面毛状体密度比 30/25°C 或 20/15°C 高 2 倍，从而间接影响每平方厘米的姜黄烯含量。在 LD 下，温度方案对毛状体密度或姜黄烯含量几乎没有影响，尽管毛状体密度大于或等于 SD。
