At night, transpiration usually does not occur, because most plants have their stomata closed. When there is a high soil moisture level, water will enter plant roots, because the water potential of the roots is lower than in the soil solution. The water will accumulate in the plant, creating a slight root pressure.
Cladosporium cladosporioides occurs outdoor environments year-round with peak spore concentration in the air occurring in summer where levels can range from 2,000 spores up to 50,000 spores per cubic meter of air. [16] It is among the most common of all outdoor airborne fungi, [16] colonizing plant materials and soil. [14]
Cladosporium species are present in the human mycobiome but are rarely pathogenic to humans. They have been reported to cause infections of the skin and toenails as well as sinuses and lungs, with more common symptoms including nasal congestion, sneezing, coughing, and itchy eyes. [8]
Outdoors, molds play an important role in breaking down organic matter like decaying leaves, but inside, mold can spoil foods or grow on damp surfaces and should be avoided, according to the EPA ...
Mold spores are often spherical or ovoid single cells, but can be multicellular and variously shaped. Spores may cling to clothing or fur; some are able to survive extremes of temperature and pressure. Although molds can grow on dead organic matter everywhere in nature, their presence is visible to the unaided eye only when they form large ...
Mold illness isn’t easy to define, and the path from home mold growth to debilitating chronic health symptoms is complicated. But often the story starts like this: Moisture in a home can cause ...
Sooty mold is commonly seen on the leaves of ornamental plants such as azaleas, gardenias, camellias, crepe myrtles, Mangifera and laurels. Karuka is affected by sooty mold caused by Meliola juttingii. [6] Plants located under pecan or hickory trees are particularly susceptible to sooty mold, because honeydew-secreting insects often inhabit ...
Leaf mold is not high in nutrient content but is an excellent humic soil conditioner because its structure and moisture retention provide a good growing medium for seedling roots. Leaves collected from roads and pavements may be contaminated by pollutants which can become more concentrated as the leaves decompose into a smaller volume [ 11 ]
