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 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...
متن کاملeffect of different substrates on tomato production in soilless culture
abstract this study was performed in order to determine a suitable alternative substrate for peat in soilless culture in 2007. different plant wastes including carbonized rice hull, saw dust and dry pine leaves (pinus eldarica) were examined. treatments were 100% peat as control, peat plus dry pine leaves (1:1 v/v), peat plus carbonized rice hull (1:1 v/v) and peat plus saw dust (1:1 v/v). the ...
متن کاملReduced Lateral Root Branching Density Improves Drought Tolerance in Maize.
An emerging paradigm is that root traits that reduce the metabolic costs of soil exploration improve the acquisition of limiting soil resources. Here, we test the hypothesis that reduced lateral root branching density will improve drought tolerance in maize (Zea mays) by reducing the metabolic costs of soil exploration, permitting greater axial root elongation, greater rooting depth, and thereb...
متن کاملSerum Iron Concentration in Children with Giardiasis
SUMMARY Giardia is a protozoan parasite which exists in the small intestine in man. This parasite could act as a barrier against fat absorption. It also results in anemia as a result of interference with folic acid vitamin B6 and probably iron absorption. In this study a total of 198 infested and 35 noninfested school children were studied for serum Iron and TIBC. The results showed the Iron...
