A leaf covered with vaseline on the lower surface wont have any affect as the stomata are being covered with the vaseline but if it were on the upper surface it would shrivel because When a leaf is loosing a lot of water vapor , it exposes the least amount of surface area to evaporation so it shrivels.
the vaseline would act as a cuticle and protect the plant more.
When leaf surface is coated with Vaseline then plant will start getting yellow with the passage of time because Vaseline will stop the process of photosynthesis. This yellowing is known as chlorosis.
The leaves of Betula populifolia are smooth on the lower surface.
A dog is likely chewing or urinating on the leaves.

is that the fallen leaves they are lower to the ground they don't get as....
From what I know about plants, the leaves have stoma in the bottom layer. Stoma are holes, through which excess water moves out of during transpiration The weather, humidity, water potential gradients and temperature all affect transpiration rates.
Narrow, thin leaves have lower pressure under water.
