EXCESS PHOSPHORUS and IRON CHLOROSIS
early in the season were less legetative than thobe taken in August and September. The light intensity and light duration to completely keep the standard cultivars vegetatile is 10 to 20 foot-candles for one hour in the middle of the night. A recent experiment on ‘Paul Mikkelsen’ grown at 70’ F revealed that lighting for four hours (10 p.m. to 2 a.m.) with a minimum of 10 foot-candles is necess...

متن کاملLime-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 کاملThe Phosphorus-Iron Relationship in Genetical Chlorosis.
Variegation of leaves is found widely distributed in the genera of the plant kingdom. Many forms are of great intrinsic beauty and are therefore a common feature in estates and gardens. The chlorotic areas usually appear as pale edges of varying width and regularity around and overlying an otherwise apparently normal green leaf, but very often whole leafy branches may appear colourless while ot...
