PCA Exam Defoliants Defoliation Leaf loss or leaf absicisson. In cotton production, it usually refers to leaf loss associated with application of a chemical that injures the leaf. Defoliation can also occur through natural leaf maturation and senessence, particularly with cooling weather after boll development Desiccation acclereated drying of plant tissue Harvest Aid Chemical chemicals with various modes of action that facilitate machine harvest by influencing boll opening, reduci...

What are target cells? - Answer Cells with receptor proteins on their cell surface membrane complimentary to the chemical What are meristems? - Answer Regions of actively dividing cells e.g. roots and shoots What do cytokinins do? - Answer promote cell division of stem and promote growth of lateral buds How do auxins cause cell elongation? - Answer Causes cell elongation by active transport of hydrogen ions into the cell walls, which lowers pH, making the cell walls flexible. Ce...

The 'classical' five naturally occurring plant hormone groups auxins, cytokinins, ethylene, gibberellins, abscisic acid The primary physiological processes regulated by auxins cell enlargement, cell expansion, stimulates production of ethylene, promotes or delays abscission, and initiates adventitious roots The primary physiological processes regulated by cytokinins cytokinesis, tissue differentiation, budbreak, apical dominance, delays senescence, and promotes cotyledon expan...
