The Role Of Electrostatic In The Pollination Of Wind-pollinated Plants

Using original design wind-pollinated plant pollen electrostatic detection apparatus, in the spring of2011-2013years.A study of four gymnosperms and five angiosperms of airborne pollen grains of charge, and its results are more consistent, airborne pollens most wind-pollinated plants with a positive charge, and its positive, negative, zero Charge pollen ratio is2:1:1. This is the first in this field presented pollen energized ratio.2, study2farming planting plants stigmas and two farming planting the plant surface charge, and the results show that the surface potential is0, the weak charged with the process plant pollen close to the tip effect exists but it is not clear that some inflorescence of plants and ancillary structures larger significance.3, observational study of wind-pollinated plant pollination process electrostatic interaction. Electrostatic interactions found in wind pollination process enhancement is significant, depending on the specific plant flowers and inflorescence part of the structure has to adapt to the diversity of diversity. Plant stigma and pollination drops on with positive and negative charge are attracted effect airborne pollen, pollen zero charge is random, there is some literature that conventional pollen exclusion of negative charge phenomenon, described the nature, natural evolution is avoiding disadvantages, the pursuit of maximum benefit. Poplar (Populus tomentosa) for example, the female flower bracts in shape and has a number of villous structure is very special, like a comb in general, can be brought about by the wind pollen1-n times interception, some wind-pollinated After a1-n pollen will attract collision retention times increased n times the chance of sticking to the stigma, stigma surface with adhesive layer, very thin, and the adhesive strength is very large, thus completing pollination. And Populus inflorescence structure particularly adapted, for example, two female flower bracts will be placed in the middle of a stigma in the pollen trapped between the two bracts movement, it will also increase the sticky pollen on the stigma opportunities.In addition, we first observed the pollination drops of juniper shrinkage. Sabina pollination drops falling on juniper pollen immediately after the contraction in the fully retracted within15-20minutes into the ovule and pollen into the ovule. But other kinds of impurities such as dust or pollen does not raise up off the contractile response. This shows Sabina pollination drops juniper pollen can specifically identify and brought it into the ovule to complete pollination.4. Special original equipment is a direct visual detection of wind-borne pollen surface and ground planting of charge of the case, which shows that in the past there are some articles are based on the aircraft at high altitude atmospheric electric fields to detect a deduction to the ground, and as the analysis the basis is not appropriate, at least need to be open to question.
