using a 1 to 5 scale (1 = plants were completely green, 2 = plants began losing greenness, 3 = signs of chlorosis and necrosis were visible, 4 = chlorosis and necrosis was severe, and 5 = plants were completely dead) ( Fig. 2 ). Data on plant greenness
transplanting. Most of the cultivars were tolerant of clomazone, chlorosis was minor and short lived, and yields were not reduced. Three cabbage cultivars that exhibited higher levels of chlorosis, including the important hybrid cultivar, Bravo, also had yields
2-mm diameter) or chlorosis were recorded in each treatment. The most recently fully developed leaf (leaf 6 from the apex) from all six plants in each treatment was sampled for measuring leaf length and width. Relative chlorophyll contents of the
, Civitas is applied at 2.5% to 5% concentrations and can result in turf chlorosis within hours of application. To mask the chlorosis, Civitas is applied with Harmonizer™ (Suncor Energy), which is a green phthalocyanine pigment ( Nash, 2011 ). This type of
In Central America and the Caribbean, bean golden yellow mosaic virus (BGYMV) can cause significant reductions in seed yield and quality ( Morales, 2000 ). Symptoms incited by this whitefly-transmitted geminivirus include intense leaf chlorosis
and mitigation of Fe-deficiency chlorosis in crop plants. Plants have two strategies for Fe uptake: strategy I depends on the reduction of ferric Fe in dicotyledon and nongrass monocotyledon plants, and strategy II relies on releasing siderophore to
solution pH and thus limited nutrient availability and uptake. By 8 WAT, all cultivars grown in substrates incorporated with DL+HL exhibited chlorosis (yellowing) and interveinal chlorosis, which is speculated to be high pH–induced Fe deficiency ( Fig. 4
exhibit leaf chlorosis in high-pH soils ( Luby et al., 2003 ; Renquist and Hughes, 1985 ). Research on strawberries in high-pH soil conditions is limited ( Renquist and Hughes, 1985 ; Rowley et al., 2010 ; Zaiter et al., 1993 ) and some of the older
Agriculture Organization of the United Nations, 2012 ). Calcareous soils, where cowpea is often grown, cover more than 30% of the earth’s soil surface ( George et al., 2012 ). When grown at pH >7.5, cowpea develops severe leaf chlorosis caused by deficiencies
Abstract
Termination of liquid fertilizer application at the visible bud stage or 2 weeks later during production of potted Lilium longiflorum Thunb. ‘Nellie White’ increased foliar chlorosis development relative to fertilization until harvest on plants stored for 3 weeks at 2C in the dark. Drenches of ancymidol applied during early production increased poststorage foliar chlorosis and bud abortion. Polyethylene (PE) lining of boxes used for cold storage and simulated shipment of potted lilies reduced water loss but did not affect subsequent floral longevity, but abortion, or foliar chlorosis. Spermidine application before boxed storage did not influence foliar chlorosis.
