063. Cauliflower Plant

Nitrogen dificiency

Growth dwarfed, erect and stem thin; leaves pale green and older leaves bright orange, red and purple tints.

 
Cauliflower Plant - Calcium deficiency 064. Cauliflower Plant

Calcium deficiency

Hooking of young leaves and severe collapse of tissues.

 
Cauliflower Plant - Calcium deficiency and manganese toxicity (soil scidity complex) 065. Cauliflower Plant

Calcium deficiency and manganese toxicity (soil scidity complex)

Calcium deficiency shows as collapse of mesophyll tissues and manganese toxicity as incurling of leaf margins followed by marginal spotting and scorching.

 
Cauliflower Plant - Magnesium deficiency 066. Cauliflower Plant

Magnesium deficiency

Older leaves chlorotic marbling followed by strong orange, red and purple tinting.

 
Young Cauliflower Plants - Magnesium deficiency 067. Young Cauliflower Plants

Magnesium deficiency

Plants in seed bed. Older leaves strong yellow, red and purple tints as "marbled" pattern.

 
Cauliflower Plants - Magnesium deficiency 068. Cauliflower Plants

Magnesium deficiency

General field view at cutting time. Older leaves strong chlorotic marbling and tinting.

 
Cauliflower Plant - Magnesium deficiency and Manganese toxicity (soil acidity complex) 069. Cauliflower Plant

Magnesium deficiency and Manganese toxicity (soil acidity complex)

Magnesium deficiency shows as chlorotic marbling of older leaves and manganese toxicity as incurling and necrosis of margins of younger leaves.

 
Cauliflower Plant - Potassium deficiency 070. Cauliflower Plant

Potassium deficiency

Leaves bluish green and slight intervenal chlorosis near margins; backward curling of laminae, and scorching and forward curling of margins.

 
Cauliflower Plants - Potassium deficiency 071. Cauliflower Plants

Potassium deficiency

General field view at cutting time; curling and severe marginal and intervenal scorching of leaves.

 
Cauliflower Plant - Manganese toxicity (soil acidity complex) 072. Cauliflower Plant

Manganese toxicity (soil acidity complex)

Restricted lateral growth of leaf laminae and incurling and brown spotting of margins (cf. Plate No. 079, molybdenum deficiency).

 
Cauliflower Head - Boron deficiency 073. Cauliflower Head

Boron deficiency

Browning of curd.

 
Cauliflower Head and Stem - Boron deficiency 074. Cauliflower Head and Stem

Boron deficiency

Longitudinal section. Browning of curd and lesions in pith. (Not specific for boron; may be due to other causes in the field)

 
Cauliflower Head and Stem - Boron deficiency 075. Cauliflower Head and Stem

Boron deficiency

Longitudinal section; Secondary infection of Bacillus Carotovorus.

 
Cauliflower Stem and Petioles - Boron deficiency 076. Cauliflower Stem and Petioles

Boron Deficiency

Corky condition of epidermis.

 
Cauliflower Leaves - Boron deficiency 077. Cauliflower Leaves

Boron deficiency

Marginal mottling; corky upper surface of midribs.

 
Young Cauliflower Plants - Molybdenum deficiency 078. Young Cauliflower Plants

Molybdenum deficiency

Leaves slightly cupped and show chlorotic mottling; tips develop dead patches; cotyledons remain dark green. (Similar to manganese toxicity) (cf. Plate No. 072)

 
Cauliflower Plant - Molybdenum deficiency 079. Cauliflower Plant

Molybdenum deficiency

Laminae of leaves restricted and may fail to develop, leaving only bare midribs. Growing point dies.
