Lime-Induced Chlorosis
Lime-induced iron chlorosis in citrus and avocado trees may be controlled by chelating agents, such as EDTA-ethylene-diaminetetraacetic acid. Chelating agents have the ability to form complex compounds with metal ions-iron, zinc, manganese, and magnesium-holding the metals in a soluble form in various degrees of tenacity. Iron is held most firmly and, for this reason, the prospects may be best ...
متن کاملAtrazine-induced chlorosis in Synechococcus elongatus cells.
The effects of a widely used herbicide, atrazine, on the freshwater cyanobacterium Synechococcus elongatus were studied. The cyanobacteria were exposed to varying concentrations of atrazine (0.025, 0.05, 0.1, 0.25, and 0.75 microM) for 96 h. Different parameters such as growth, autofluorescence of chlorophyll a, pigment content, volume, and internal granularity of the cells were determined dail...
متن کاملPrecision phenotyping of imidazolinone-induced chlorosis in sunflower
Chlorosis level is a useful parameter to assess imidazolinone resistance in sunflower (Helianthus annuus L.). The aim of this study was to quantify chlorosis through two different methods in sunflower plantlets treated with imazapyr. The genotypes used in this study were two inbred lines reported to be different in their resistance to imidazolinones. Chlorosis was evaluated by spectrophotometri...

متن کاملNitrogen starvation-induced chlorosis in Synechococcus PCC 7942. Low-level photosynthesis as a mechanism of long-term survival.
Cells of the non-diazotrophic cyanobacterium Synechococcus sp. strain PCC 7942 acclimate to nitrogen deprivation by differentiating into non-pigmented resting cells, which are able to survive prolonged periods of starvation. In this study, the physiological properties of the long-term nitrogen-starved cells are investigated in an attempt to elucidate the mechanisms of maintenance of viability. ...
