Effects of ferrous iron (Fe) on the germination and root ...

Laboratory experiments were conducted to analyze the iron (Fe) tolerance of paddy weeds and rice varieties (Oryza sativa) for germination and root elongation. Under a waterlogged soil condition, the Fe(II) content in a soil solution increased with an increase in the ratio of rice straw to the soil.

Soil compaction | UMN Extension

Most effects of compaction are detrimental to plant growth. However, there are a few exceptions. Slightly compacted soils in a dry year can increase crop yield as discussed earlier. Another exception is the case of iron deficiency in soybeans.

Science Fair Projects - PURPOSE

The results of the experiment were: Magnets do have an effect on the growth of radish seedlings, but I can''t show this in my graphs because of the method I used to measure them. When I pulled the plants I could see that the magnet had affected the plants because they were all facing the middle where the magnet was placed.

Effect of heavy metals on germination of seeds

Heavy metals including lead, nickel, cadmium, copper, cobalt, chromium and mercury are important environmental pollutants that cause toxic effects to plants; thus, lessening productivity and posing dangerous threats to the agro-ecosystems. They act as stress to plants and affect the plant physiology.

Heavy metals and living systems: An overview

Plants experience oxidative stress upon exposure to heavy metals that leads to cellular damage and disturbance of cellular ionic homeostasis. To minimize the detrimental effects of heavy metal exposure and their accumulation, plants have evolved detoxification mechanisms mainly based on chelation and subcellular compartmentalization.
