This result in greater soil moisture content in ecosystems rich with CO2, this increases plant growth In a review of studies conducted over the prior decade, Pospisilova and Catsky (1999) compiled over 150 individual plant water use responses to atmospheric CO2 enrichment.
They found that elevated CO2 increased rates of net photosynthesis in about 85% of the reported studies, while reducing stomatal conductances and rates of transpiration in approximately 75% of the cases analyzed....
Every autumn we revel in the beauty of the fall colors. The mixture of red, purple, orange and yellow is the result of chemical processes that take place in the tree as the seasons change from summer to winter.
During the spring and summer the leaves have served as factories where most of the foods necessary for the tree's growth are manufactured. This food-making process takes place in the leaf in numerous cells containing chlorophyll, which gives the leaf its green color. This extraordinary chemical absorbs from sunlight the energy that is used in transforming carbon dioxide and water to carbohydrates, such as sugars and starch.
The Sun ( G2) radiates light in a particular distribution of colors, emitting more of some colors than others. Gases in Earth's atmosphere subsequently filter that sunlight, absorbing some colors (wavelengths), and so more red light photons reach Earth's surface than blue or green ones. Not surprisingly then, photosynthetic life on Earth's land surfaces such as plants (which includes multicellular organisms from grass to trees) tends to depend mostly on red light, because it is the most abundant wavelength reaching the surface, and on blue light, because it is the most energetic. Earth plants also absorb green light, but not as strongly, so leaves look green to the eye, having adapted to the conditions most commonly found around our Sun and on Earth's planetary surface. As most stars do not have the same distribution of light in color wavelengths as our Sun, however, some researchers hypothesize that photosynthetic life on extrasolar planets will not necessarily have the same colors as on Earth.
Chickpea plants irrigated with magnetized water grew taller and heavier than plants irrigated with tap water (Hozayn and Qados, 2010). The authors attribute this stimulation to an increase in photosynthetic pigments, where the magnetic water induces cell metabolism and mitosis meristematic cells in pea, lentil and flax (Belyavskaya, 2001). Additionally, it is believed that new protein bands are formed in plants that are treated with magnetic water, and that these proteins are responsible for increased growth (Hozayn and Qados, 2010). MW has been linked to increases in photosynthetic pigments, endogenous promotors, total phenol and protein biosynthesis in plants (Qados and Hozayn, 2010 and Shabrangi and Majd, 2009).
If placed in a suitable nutrient environment, cells and tissues of many organisms are ableto reproduce and form new plants or animals. Now, we will deal with vegetable tissues,whose culture is simpler than that of animal cellules and tissues. It is necessary toprepare a nutritive and sterilized culture medium for the piece of plant tissue. Keep theculture in the suitable conditions of light and temperature and which vary from plant toplant. Over many days, you will observe the growth of a callus or roots or shoots. In thisway you can obtain even whole plants (cloning). These experiments show that special cellskeep all the information necessary to generate the whole plant.
As we have mentioned, it is necessary avoid bacteria and moulds in the cultures. For thisyou will need sterilize tools, vials, tubes, and nutrient medium. Place each in anautoclave for a ten minutes or, lacking an autoclave, a pressure cooker. The tissues aswell have to be free from microorganisms and they have to be sterilized with bleach (40%solution for 15 min) or with alcohol.
The transfer of the tissues into the test tubes has to be made in aseptic conditions,using a sterile box. Lacking that, make your first trials in a quiet place, as devoid ofwind and dust as possible. The culture medium should contain water, vitamins (particularlythose of the B-complex. For this, use yeast extract), sugars, mineral salts. To enrich thewater with mineral salts, boil some water with a handful of soil, then let settle andfilter it. Usually, people also insert 0.5-0.8% of agar-agar to "solidify" themedium. As culture medium, coconut milk has been used. It contains mineral salts, sugars,vitamins and growth hormones.
1 - For yours first tests of micropropagation, use strawberries tissues.
2 - If this simple experiment interests you, you can continue on the way of the invitro culture of vegetable tissues. In fact you can propagate a lot of plants in thisway. Plants easy to culture are the following: tomato, potato, strawberry, chrysanthemum,geranium, sunflower, tobacco, carrot and onion. You can use tissues obtained from seeds,such as the embryo, but you can use also tissues taken from adult plants, such as tissuesof roots, stems, apical buds, shoots, leaves, even single cells. Each plant and tissue hasits own needs. They are different from each other. You can try the influence of thevegetable hormones, special nutrients, etc.
This field is very broad and complex so, if you are interested in continuing with theseexperiments, you can buy special books and you should build a sterile box.

Today Day 7) Tap: growth of 1". Slightly greener but still has some brown coloring , new red patch on stock, growth of two new stocks sprouting On the base. Imploder: growth of 2.5". Two new stocks spouting from base. Bright green and much straighter than the other. So far the the plant with the imploder water has double the growth compared to the tap water plant. Very impressive !
Day 1) Tap : no significant change in growth. Looking a bit more brown. Imploder: immediate noticeable growth of 1/4" - 1/2". Plant is noticeably greener , straighter and has a new patch of red on the stock.
I bought two identical plant packages and used the imploder water on one and tap water in the other. The first thing noticed was that the imploder water absorbed the soil in about 1-2 minutes, leaving the soil looking moist & fluffy and the tap water absorbed the soil after about 30 minutes. Even after 40 minutes the tap water Was not completely absorbed and made the soil into a sloshy mud. Both plants are placed in the same soil, same sized pot and in place in the same sunlight. The only difference between the two is the water.
