Relative humidity The measurement of the amount of moisture in the atmosphere.
Reticulate Like a net, the interstices closed. Usually referring to the veins of a leaf.
Reniformis/reniforme Epithet meaning kidney shaped.
relative humidity The ratio of water vapor in the air to the amount of water vapor the air could hold at the current temperature and pressure.
Relative humidity should be kept in the 55-70% range. Keep the plant on a pebble tray or sphagnum moss to ensure the proper humidity. Dendrobiums prefer the same room temperatures as we do. Daytime temperatures should be between 70 and 85 degrees F.
Conidia germinate in the high relative humidity usually available on the leaf surface at 50 to 77 F (10-25 C) with an optimum of 66 to 72 F (19-22 C). Germination does not occur in free moisture.
This requires exposure to 100% relative humidity for an extended period. Since wood is seldom exposed to this level of relative humidity for long periods, it seldom reaches fiber saturation because of high humidity.
Because of the superficial nature of this growth, it is extremely sensitive to the microclimate conditions (particularly relative humidity) immediately surrounding the fruit.
Plants typically need a high relative humidity to thrive, usually around 80 percent. This presents a problem since most households have a relative humidity around 20 to 50 percent.
Humidity: Most plants are happiest when the relative humidity is 50 percent or higher, though they can usually survive at 30 to 40 percent.
Amazon lilies require relative humidity of 40 percent or more -- something that can be difficult for windowsill gardeners to provide.
Very useful in the glass house is a meter to measure relative humidity. On a hot day plants can cook if humidity is not lifted to balance the heat.
These plants thrive in 50 to 80 percent relative humidity. To increase humidity, run a room humidifier or place the pot on a tray filled with pebbles and water.
Once fruit is fully ripe, it can be stored at 45 to 50 degrees F with a relative humidity of 90 - 95%.
There is light precipitation, abundant sunshine, and low relative humidity. Humidities range from 60% (mornings) to 30% (afternoons). All of New Mexico receives at least 70% sunshine year-round, and is called the "The Land of Enchantment." ...
increased humidity are by attaching a humidifier to the heating or ventilating system in the home or placing gravel trays (in which an even moisture level is maintained) under the flower pots or containers. This will increase the relative humidity in ...
Potatoes can also be properly cured after harvest if they are stored at 60 to 75F and 80 to 90 percent relative humidity for one to two weeks.
Don't wash potatoes you want to store—simply brush off the soil after it dries.
' They grow well in a temperature range of 55-90 degrees F and in relative humidity of 50-75 percent.
Hygrometer - instrument for measuring relative humidity in the atmosphere A hygrometer will save time, frustration and money.

Inbred - (true breed) offspring of plants of the same breed or ancestry.
The high relative humidity caused by those conditions is ideal for the growth and sporulation of plant pathogenic organisms and therefore foliar pathogens may continue to be more prevalent in 2011 than in other years.
Common storage (at low temperatures 32 to 40F and high humidity -- relative humidity greater than 90%) Frozen, canned, pickled

INFLORESCENCE -- The arrangement of flowers on the stem. A flower head.
Misting will not only help it multiply, but will keep the spider mite population down as well. A relative humidity of 70 per cent is ideal for P. persimilis. Once its food supply is exhausted, the numbers of P. persimilis will decline as well.
Last year's leaves, once they have been hit by the disease, will always have it, with symptoms persisting from year to year until the leaves drop off. High relative humidity at night and low relative humidity during day with 70-80 F (22-27 C) ...
5 kilograms and are a compact 15 by 22 centimetres-need to be placed in a humid area (somewhere between 80 and 95 per cent relative humidity) with a temperature range between 12 and 20˚C; so avoid the main part of your home or greenhouse.
After curing, store them in a dry, cool place with good air circulation and temperatures around 50-55 degrees with relative humidity of 50-70%.
Finally, keep palm fronds clean. Spider mites are attracted to dusty foliage and can balloon into a serious problem, particularly in winter when relative humidity is low indoors.

Above 93F, there is a risk of no flowering at all. Relative humidity should remain at a constant level of 75‐85 percent. High humidity levels above 90 percent can result in loss of leaves, yellow leaf spots and damaged flower heads and buds.
If the air is too dry or wet, you might want to invest in a humidifier, dehumidifier, or a combination unit. If your plants are too dry, misting them with water will help raise the relative humidity.
