Researches the kinds of melancholy pollination of both alfalfa: long, weather proof and midday arid haired after biogenetic. Pollination’s mid, day melancholy found in caribou watch days in a temperature of over or around 30°. In the times, the pollination of alfalfa begins shortly following seven weeks, afterward it immediately grows and reaches on that the original (dawn) maximum approximately 11 hrs. Watch pollination is, lessened, there is with a day melancholy. Subsequently it raises at the early day, accomplishing out the minute (day) packed with 17 hrs. At the hours, which followed closely the pollination falls approximately and radically or following 20 hrs. stopped. So, pollination of alfalfa in rather sexy times it flows into a double peak curve; nonetheless, it really is distinguished through afternoon and morning peaks and day melancholy of its own. The relative humidity of this atmosphere throughout the day melancholy of pollination fluctuates within broad boundaries (approximately 55 %).
Even though it seems probably N, it is perhaps not secure to state its significance to bees. Even the day melancholy of pollination can be termed, obviously, combined with excessively large fever, solar power, which also revealed I. Selenic (1934), which contributes to a stunning, occasionally fatal growth in the body temperature of pests, especially bumblebees. In the cold hours and days of this afternoon. Paid down bees flight exercise, and there is a dip within their own flight as the person. That we watched in melisma along with mellitus. Through curve days using a maximum temperature of pollination of alfalfa flows in gruesome arch electronic. It really is most knowingly, transported outside at ancient day (15) hrs. This is actually true from the summer 1950.
A dip in pollination in 13 H30. 1950, making the looks Bi Modal curve resulted from this small decreasing of this warmth to 22.2° in relation to all the cloud inside this hour. The curve of diurnal pollination for many times of observations 1950 being an entire was on average unimodal, also that the Scorching long term melancholy of pollination we watched that the most powerful phase of atmospheric and dirt warm at the previous week of July 1952 the normal fever and ordinary relative humidity in 14 was at this age, respectively. Equal to 30.8° and 31 percent. About respective times, the most fever climbed into 38.5°, and the minimal relative humidity fell into 23 percent. The Pollination of all alfalfa out of the blue decline to 50 percent, also approximately and also farther stably retained in the degree of both 2030.
Depression pollination lasting and sustained, it manifests itself onto the background well weather and arch, it would appear beneficial for bees. Alfalfa blooming but did not give to odor. Fields are, represented with a carpet with stains of cream blossoms and yellow. Abscission and wilting of blossoms neo pithy, to alter the color to purple blue, white and light yellow. Alfalfa hushed: they have very few bees. Abundantly they were, left by alfalfa. Just from the less warm instances of this afternoon with 8 to 10 hens and out of 18 to 20 around alfalfa seemed several solitary bees (Mulita leporine, Plitt clavicorns, Euchre longicorn’s, Bryophytes canes, Mega Chile, etc.) plus rather a sizable variety of bumblebees (Boom bus, B. leases, B. eustress). Appeared a few honeybees.
From alfalfa’s blossoms had nectar; since the drought experienced a very poor effect on nectar collection, nonetheless, it remains viscous and thick. This material of nectar in a drought dip that the moose is all about 4 days of 0.03 is 0.12 milligrams (Pomona, 19546, p. 13). Depression pollination is quite much like this Meridian that the last since it prolonged its own limits. Each are due by essentially the very same good reasons; high fever (that the most important explanation), tingling of their atmosphere and lead solar power that exerts the adverse impact on bee elevated temperature. At the very first instance (sultry melancholy), both those f and the Torah are long lasting (to get a few days in the early morning to day), also at the next instance (day melancholy) just temporary (brief period Id).
Inside this respect, among a midday melancholy of pollination and hot, there is really a gap. That is substantial. From the very first scenario, Lucerne is pollination it’s feeble and really free flowering, whereas alternatively, at the scenario, pollination is carried out and also the blossom looks bad, but because blossoms of alfalfa disappear. Scorching sadness of pollination is, distinguished by electronically blossoms. We thought that this scenario has been that the reason for pollination’s depression. Nevertheless, it is not. Scorching depression pollination is not a decrease in nectarine idea how to negative result of elevated temperature. We are going to need to reevaluate a dilemma at which we will discuss the part of nectarine from the practice of pollination of alfalfa. 8 decades of observations and Z long term melancholy pollination of alfalfa that individuals observed just one time by the close of June 1952 she is still here, evidently, infrequent.
