Phylloxera infested grapevines have reduced chlorophyll and increased photoprotective pigment content – can leaf pigment composition aid pest detection?
Grape phylloxera is a root-feeding pest of grapevines. In Australia, phylloxera infested vineyards are subjected to quarantine restrictions and early detection remains vital for the timely implementation of post-outbreak quarantine protocols. Current detection methods rely on time-consuming ground surveying which involves detailed examination of grapevine (Vitis vinifera L.) root systems. Leaf ...
متن کاملEffects of Water Stress and Fusarium oxysporum f. sp. lycoperseci on Growth (leaf area, plant height, shoot dry matter) and Shoot Nitrogen Content of Tomatoes Under Greenhouse Conditions
Effects of water stress and Fusarium oxysporum f. sp. lycoperseci (Fol) on the growth of tomatoes were studied in a greenhouse experiment. Treatments consisted of five levels of water stress (1, 3, 5, 7 and 9 day irrigation intervals). Infested soil consisting of 400 chlamydospores g1 of Fol and non infested soil were used. Experiments arranged in a completely randomized design with 8 replicati...
متن کاملNon-destructive determination of maize leaf and canopy chlorophyll content.
The objective of this study was to develop a rapid non-destructive technique to estimate total chlorophyll (Chl) content in a maize canopy using Chl content in a single leaf. The approach was (1) to calibrate and validate a reflectance-based non-destructive technique to estimate leaf Chl in maize; (2) to quantify the relative contribution of each leaf Chl to the total Chl in the canopy; and (3)...
متن کاملEstimation of Chlorophyll Content in Papaya Leaf using Mathematical Operations
ABSTRACT Leaf color is used as a guide for assessments of nutrient status and plant’s health. So that a new method is proposed for the detection of Chlorophyll content based on the leaf color. Based on green color present in leaf we can estimate the chlorophyll content in leaf. The proposed equation produced superior results with the true value of chlorophyll content measured in the laboratory ...
