Mechanical injury of wind to recently transplanted cacao seedlings as related to the shade problem
Experiments in which cacao (Theobroma cacao L.) seedlings were submitted to different combinations of treatments involving protection and exposure to sunlight and wind have shown that the beneficial effect of shading in young cacao areas is due not only to reduced exposure to solar radiation but also to reduced air movement around the plants. Excessive wind caused severe mechanical injury, at the pulvinus level. Visible damage occurred only 24 hours following exposure to wind. Injury progressed rapidly, leading to intensive leaf fall if the plants were maintained under nonprotected conditions. It is suggested that wind-breaks on their own can give adequate protection to cacao plantations, by providing both lateral shade and wind shelter. This practice might permit the use of a wide range of economic trees for sheltering and would probably lead to higher yield due to higher photosynthesis
