Monitoring Optical Tool to Determine the Chlorophyll Concentration in Ornamental Plants
نویسندگان
چکیده
The accurate estimation of leaf photosynthetic pigments concentration is crucial to check the plant´s health. Traditional methods measuring involve complex procedures solvent extraction followed by spectrophotometric determinations. Portable plant instruments such as Soil Plant Analysis Development (SPAD) meters can facilitate this task for speed and simplicity measures. relationship between chlorophyll index obtained SPAD-502 pigment in several ornamental species help management production. Two trials have been carried out two different growing seasons (spring summer) facilities (greenhouse open air), involving 30 species. There was a high linear concentrations Chla Chlb, well Chlt Ct studied under greenhouse field conditions. ratio Chlb higher at conditions similar Ct. also good Chlorophyll both conditions, However, relationships with slopes were observed groups

Leaf optical properties in higher plants: linking spectral characteristics to stress and chlorophyll concentration.
A number of studies have linked responses in leaf spectral reflectance, transmittance, or absorptance to physiological stress. A variety of stressors including dehydration, flooding, freezing, ozone, herbicides, competition, disease, insects, and deficiencies in ectomycorrhizal development and N fertilization have been imposed on species ranging from grasses to conifers and deciduous trees. In ...

متن کاملA New Image Processing Based Technique to Determine Chlorophyll in Plants
Leaf colour is usually used as a guide for assessments of nutrient status and plant health. We propose a new inexpensive, hand-held and easy-to-use technique for the detection of chlorophyll content and foliar nitrogen content in plants based on leaf colour. This method provides a rapid analysis and data storage at minimal cost and does not require any technical or laboratory skills. Most of th...
متن کاملMicroprotoplast Preparation in Liliaceous Ornamental Plants
We aimed to produce intergeneric hybrid plants with only one or a few alien chromosomes via microprotoplast fusion for genetic improvement and chromosome studies in Liliaceous ornamental plants. In order to apply this technique, it is essential to establish an efficient system for mass-preparation of microprotoplasts. We have established 2 different systems for isolating microprotoplasts, one f...
متن کاملThe Response of Ornamental Plants to Saline Irrigation Water
Salinity affects about one third of irrigated land, causing a significant reduction in crop productivity (Flowers & Yeo, 1995; Ravindran et al., 2007). For this reason researchers have paid considerable attention to this important environmental problem over the last decades. Few studies, however, have dealt specifically with ornamental plants used in landscapes, despite the fact that salt stres...
