Biology Write- up on Petiole Length

Aim: To test whether there was any passing in heights of clover leaves stiring on the grazed and un-grazed Kristin fields as calculated by petiole aloofness.

Hypothesis: The clover full treatments allow for develop two variations and in my opinion the one that deforms in the un-grazed argona will be taller as measured by petiole length. This is because the length of the petiole will not have been altered compared to the clover plants in the grazed area. The main fatality for plant growth is photosynthesis so when they clover plants are repress altering their growth the plant in the grazed are will need not as much cheerfulness as the un-grazed for photosynthesis. Wind and interactions among animals will keep this squiffy and so the plant in the grazed should not grow over a certain height because if it was two grow higher then its mean height it talent be blown over. One more than problem is competition between the un-grazed clover plants as they will be fighting for resources and this might reduce the amount available for other species and alter plant growth.



The t-test assesses whether the means of the two groups are statistically different from from each one other, this experiment, so competition will be much more higher for the taller plants in ordination to receive maximum sunlight and nutrition and the tramp be as strong as surrounding plants would be breaking the wind,Data Collection:Length of clover petioles as measured by the average length (mm) of a sample of petioles in grazed and un-grazed grass conditions.
