Introduction
The observations support the our hypothesis about the active condensation of atmospheric moisture on the surface of plant leaves and shoots at a temperature below the dew point. The phenomenon is usually observed in the absence of direct sunlight. The accumulation of condensation leads to the Self-Moisturing Effect (SME) - a mechanism capable of ensuring the survival of the plants with a lack of natural precipitation in the form of rain or fog.

The purpose of the work was to experimentally determine the amount of moisture that can condense on the surface of the plant when cooled below the dew point. To estimate the amount of condensed water on a surface cooled below the dew point, a unit with a thermoelectric module with an area of 9 cm2 was assembled. It was established that the water co...

The amount of moisture that can condense on the surface of the plant when cooled below the dew point is experimentally determined. It was found that the water condensation coefficient KC varies in the range from 1.3 to 2.1 mg / (cm2 x hour x deg) depending on the value of relative humidity and air temperature, which corresponds to 156 ... 252 grams...

Since 2010, descriptions of 20 new forms and hybrids of woody plants have been published in the Hortus Botanicus journal, 7 have already been included in the International Plant Names Index. The origin of 19 samples was established: 6 of them are of natural origin; 3 were received from botanical gardens; 9 - from self-seeding or seeds collected in...

Changes in the temperature of the surface of the plant were studied to determine the significance of water condensation on the surface of plants and the relationship between this phenomenon and climatic environmental factors. For 30 hours at night, conditions favored the precipitation of fog, and due to a decrease in the temperature of the surface...

The article covers water condensation on the surface of plants. It is suggested, that there are mechanisms capable of ensuring plant survival when lacking natural precipitation in the form of rain or fog. The self-irrigation ability allows botanical gardens to create plant expositions of plants that do not need watering in local conditions, forming...

It is hard to lose a teacher, who used to direct you. It is sad and bitter to lose a colleague, who you used to work with for many years. It is unbearably painful to lose a friend, with whom you have gone through so much together. Doctor of biology, Professor, director and creator of the Kuban Subtropical Botanical Garden, chairman of Dendrology...

The essay briefly touches upon the main mechanisms to cool down the plats’ surfaces that lead to condensation of atmospheric moisture; methods for experimental verification of these mechanisms are presented therein.
Article
Full-text available
The value of the observed phenomenon of condensation of atmospheric moisture by cooling the plant leaves and shoots to a temperature below the dew point is largely determined by climatic parameters. Comparison of the deviation of the average monthly temperature of the dew point in the different regions of the world allows us to assert the universal...

Studies conducted at the Subtropical Botanical Garden of Kuban (Utch-Dere, Sochi) pretty much allow to explain the abnormally high drought resistance of Liriope graminifolia Lour. and Ophiopogon japonicus Ker.-Gawl., plants that naturally grow mostly in sufficient humidity. Quite low temperatures of the leaves’ surface allow to effectively condense...

This paper is devoted to some peculiarities of water condensation on the surface of plants . Arguments in support of the hypothesis that in decreasing temperature of leaves and shoots below the dew point, the plant can actively condense moisture from the air, increasing the duration of dewfall are presented. Evening dewfall on plant surfaces begins...

Высокие темпы развития научно-технического прогресса, сопряженные со стремительными изменениями в социальном устройстве российского общества, приводят к тому, что в ми- роощущении человека начинает преобладать прагматическое отношение к действительности. Однако такой подход не приближает нас к истинной гармонии в обществе и к гармонич- ным отношени...

Recently, the accents in the field of application of information technologies for needs of biological collections are displaced from registration and account in area of the analysis of the data. If to determine a biodiversity, as the genetic resources, distributed in space, it is easy to make a conclusion, that one of the most powerful tools of the...

«Calypso» is a program intended for the creation of the databases of botanical collections kept in botanical gardens and herbaria. At the present moment «Calypso» (versions from 4.0 to 4.53) is used at about 30 botanical gardens of Russia and the Ukraine, besides our garden. The program uses the international transfer format (ITF) for the botanical...

The associative absorption band for liquid water ~a is lacking for the vapor and is localized in the 2650-1850 cm -I range (Fig. i), with its maximum dependent on the phase state and temperature; the strong band due to atmospheric CO 2 in that range does not distort Va for H20 outside the range 2400-2325 cm -l. It is found [4, 5] that ~a has the fo...
