Researchers found that partial deficiencies of K or P did not change the fatty acid composition of phosphatidyl choline in Brassica napus L. plants. Calcium deficiency did, on the other hand, lead to a marked decline of polyunsaturated compounds that would be expected to have negative impacts for integrity of the plant membrane, that could ...
Detecting phosphorus deficiency can take multiple forms. A preliminary detection method is a visual inspection of plants. Darker green leaves and purplish or red pigment can indicate a deficiency in phosphorus. This method however can be an unclear diagnosis because other plant environment factors can result in similar discoloration symptoms.

In plants a micronutrient deficiency (or trace mineral deficiency) is a physiological plant disorder which occurs when a micronutrient is deficient in the soil in which a plant grows. Micronutrients are distinguished from macronutrients ( nitrogen , phosphorus , sulfur , potassium , calcium and magnesium ) by the relatively low quantities ...
In flowering plants, the central axis of the cone or fruit, e.g. in Callitris. column 1. A structure extending above the ovary and incorporating the style and stamen s also known as the gynostegium, e.g. in orchids and milkweeds. 2. In grasses, the lower, stouter, and usually twisted part of an awn, distinct from the slender upper part or bristle.
Specific nutrient deficiencies (often aggravated by high soil pH) may be corrected by supplemental feedings of iron, in the form of a chelate or sulphate, magnesium or nitrogen compounds in various combinations. If the soil is too acidic, applying lime can raise the pH to the proper range, making more nutrients available to the plant.
Food from plants. A plant-based diet is a diet consisting mostly or entirely of plant-based foods. [1] [2] Plant-based diets encompass a wide range of dietary patterns that contain low amounts of animal products and high amounts of fiber-rich [3] plant products such as vegetables, fruits, whole grains, legumes, nuts and seeds.
Maize plants with severe zinc deficiency in the foreground, with healthier plants (planted at the same time) in the background. Zinc deficiency is common in many different types of soil; some soils (sandy soils, histosols and soils developed from highly weathered parent material) have low total zinc concentrations, and others have low plant-available zinc due to strong zinc sorption ...
