  • a Mean number of TIS ± sd.

  • b Trichomes were counted only on leaves 3 and 4. Leaf length was between 4 and 5 mm. Total number of leaves was 20.

  • c Sixty-four percent flat and reduced trichomes. Due to erupting sub-epidermal trichomes, the number of trichomes in the epidermis might be overestimeated.

  • d ND, not determined.

  • e Ninety-four percent flat and reduced trichomes.

  • f Fifty-three percent flat and reduced trichomes.
