Pollination is done by certain insects, namely the cycad weevil Rhopalotria mollis. Conservation. Cardboard cycads can only be reproduced by the fleshy, brightly crimson-colored seeds producedThe surface temperature of cycad cones was analyzed using images from a thermal imager, FLIR SC620 (FLIR Systems). To eliminate the influence of solar radiation during daytime, thermal images were taken at night when the heat acquired from sun exposure is negligible. The internal temperatures of cycad cones were measured using a thermal ... ….
