One of the first changes can be obo·r :/' served in the behavior of the membranes that enpends on a little science and a lot of luck. Fortunately, tlult view is slowly clulnging as some of the art of defoliaclose and divide the compartments of the cell. These tion is replaced by science. This newsletter will revisit membranes normally permit the orderly function of some of the principles responsible for defoliation success the cell's machinery and transport of material from and highlight a new technique to schedule Iulrvest prepaone compartment to another. With continued aging, ration nodes above cracked boll (NACB). these membranes begin to leak with serious consequences. Powerful enzymes capable of dismantling The Challenge The Cooperative Plant the cell are activated. Successful defoliation is dependent on a cooperative plant. Without that cooperation, inadequate leaf drop on one hand or leaf desiccation (leaves that dry and do not drop) on the other hand are likely to result. Cotton leaves need to be persuaded or coaxed off. A heavy-handed or sledge hammer approach is not desirable.

COTTON PHYSIOLOGY TODAY Newsletter of the Cotton Physiology Education Program -- NA TIONAL COTTON COUNCIL
Peak bloom is one of the most recognizable periods in cotton development Fields may become blanketed with white blooms as boll loading accelerates to a maximum. This landmark developmental stage signals that a shift is occurring in the crop's biology and your management priorities. This newsletter will profile the crop at peak bloom and outline some management considerations that can affect per...
متن کاملUltrastructural and chemical evidence that the cell wall of green cotton fiber is suberized.
Green cotton (Gossypium hirsutum L.) fibers were shown by electron microscopy to have numerous thin concentric rings around the lumen of the cell. These rings possessed a lamellar fine structure characteristic of suberin. LiA1D(4) depolymerization and gas chromatography-mass spectrometry analysis showed the presence of a suberin polymer in the green cotton with the major aliphatic monomers bein...
متن کاملCotton fiber growth in planta and in vitro. Models for plant cell elongation and cell wall biogenesis.
There are only a few cells in the plant kingdom that are as exaggerated in their size or composition as cotton fibers. It is precisely their highly elongated structure and exceptional chemical make-up that establishes cotton fiber as an ideal model for studies of plant cell elongation and cell wall biogenesis. Cotton fibers are unicellular, therefore cell elongation can be evaluated independent...
متن کاملHigh Performance Liquid Chromatography Analysis of Carbohydrates of Cotton-Phloem Sap and of Honeydew Produced by Bemisia tabaci Feeding on Cotton.
Phloem sap from cotton (Gossypium hirsutum L.) was collected from young and mature leaves by the aphid-stylet technique. Exudate was analyzed for carbohydrates by HPLC using sensitive pulsed amperometric detection. The predominant carbohydrate present (>90%) was identified as sucrose. A second, unidentified compound that was not one of the more commonly translocated sugars was detected in matur...
متن کاملGbPDF1 is involved in cotton fiber initiation via the core cis-element HDZIP2ATATHB2.
Cotton (Gossypium spp.) fiber cells are seed trichomes derived from the epidermal layer of the cotton seed coat. The molecular components responsible for regulating fiber cell differentiation have not been fully elucidated. A cotton PROTODERMAL FACTOR1 gene (GbPDF1) was found to be expressed preferentially during fiber initiation and early elongation, with highest accumulation in fiber cells 5 ...
