      i was doing a very very simple experiment regarding transpiration

      i took a capillary tube and attached to a rubber tubing and then to a small piece of glass tube and then to another rubber tube and then to the plant shoot.
      then i noted down the hieght to which a air bubble rouse in different condition.
      under normal conditions i got 5 cm / min and under fan at speed 3 (i need to count the rpm yet) 9 cm / min. that’s all alright but under sun (varying sunlight and temperature (by 5 degrees)) i got 2 cm in 5 min
      something had gone wrong.
      i don’t know what. the temperature difference should have made a difference.

      the plant had stayed detached for 2 hours by then. but that doesn’t make a difference. if i am right

      a few other thingss had also taken place. the rubber tubings had grown looser. i think that was the reason but there was no leakage or anything nor did the water flow out when the shoot was removed.

      I only asked because CAM plants transpire less in sunlight. 🙂

      and how do they transpire less in the sun?
      do they close theirstoma and also reduce the photosynthsis ❓
      and why so? are they dessert plants or something?
      i am all questions you know
