Many planted Pinus forests are severely affected by defoliation and mortality processes caused pests droughts. The mapping of forest tree crown variables (e.g., leaf area index pigments) is particularly useful in stand delineation for the management declining forests. This work explores potential integrating multispectral WorldView-2 (WV-2) Airborne Laser Scanning (ALS) data based on selected s...

Internal browning is a physiological disorder affecting tomatoes (Solanum lycopersicum L.), and presents major problem to Japanese producers. characterized by the discoloration (browning) of inside fruits while external surface appears normal; consequently, affected reach consumers without detection. may be caused Ca deficiency suppressed performing defoliation. We investigated effect defoliati...

Application of 4-amino-3,5,6-trichloropicolinic acid (picloram) to roots stimulated the production of ethylene in both mesquite [Prosopis juliflora (Swartz) DC. var. glandulosa (Torr.) Cockerell] and huisache [Acacia farnesiana (L.) Willd.] seedlings. Herbicide levels rose in tissues before we detected increased ethylene production. Rates of ethylene production by various parts of the plant par...

Alternaria leaf blight is a much greater threat to muskmelons than watermelons. The disease is caused by a fungus (Alternaria cucumerina) that can rapidly defoliate plants, causing reductions in bulk yield. Melons on defoliated vines ripen prematurely and result in lower quality fruit compared to melons produced on healthy vines. Yield losses greater than 50% will occur in situations where the ...
