Plant Responses to Vegetation Proximity: A Whole Life Avoiding Shade

In high density of vegetation, plants detect neighbors by perceiving changes in light quality through phytochrome photoreceptors. Close vegetation proximity might result in competition for resources, such as light. To face this challenge, plants have evolved two alternative strategies: to either tolerate or avoid shade. Shade-avoiding species generally adapt their development by inducing hypoco...

Light-Induced Indeterminacy Alters Shade-Avoiding Tomato Leaf Morphology.

Plants sense the foliar shade of competitors and alter their developmental programs through the shade-avoidance response. Internode and petiole elongation, and changes in overall leaf area and leaf mass per area, are the stereotypical architectural responses to foliar shade in the shoot. However, changes in leaf shape and complexity in response to shade remain incompletely, and qualitatively, d...

Planning the shade prescription.

When a patient comes in for a consultation for aesthetic treatment, the consultation appointment is divided into two. Firstly, a conventional evaluation with charting, periodontal, occlusal and radiographic surveys, diagnostic models and photographs is performed. Secondly, an aesthetic evaluation involving aesthetic analysis and a focus on the patient’s aesthetic requests is carried out. Media ...
