It was revealed that the emptied seeds were mainly due to the self pollination through the experiments of open and self pollination.
Unlike honeybee Apis mellifera, bumblebee Bombus lucorum have different pollination behavior on greenhouse tomato.
The seed-mainatined plot is appraised continuously by the mode selection, and propagated mixedly under the open-pollination condition.
The expression of SLG and SRK genes from the treated materials was not distinctly different from that of control 8 hours after pollination.
These are the special places where a unique confluence of cultural cross-pollination, inherent creativity and a critical mass of kick-ass musicianship coalesces to create something truly special.
Pollen morphology and hydration, ovule development, formation of pollination drop and the pollination process of Taxus chinensis (Pilg.
The status of species diversity and conservation strategy of bumble bees,a pollination insect
Meanwhile, the recent high prices for pollination contracts made it look worthwhile fattening bees up with supplements over the winter.
The following technical measures must be adopted, e. g. increasing fertilizer, artificial pollination, spraying growth regulator, proper pruning, and the controlling of diseases and pests.
Theoretical analysis and indirect detection indicated that the pollen contamination rate of this pollination technique was no higher than 1%. But there is no evidence from direct detection by now.
It seems that pollination also involves certain chance factors.
These ongoing losses in the pollination army of honeybees cannot continue if we are to secure food supplies.
The final walkthrough meeting wasn't rushed, since it provided much of the cross-pollination, agreement on solutions, and discussion of impact and pros and cons.
The repeated pollination during receptive period could not significantly increase seed numbers over single pollination.
Peer reviews also improved overall team capability through cross-pollination of skills and approaches.
After observation analysis, Apis mellifera Linnaeus and Bombus ussurensis Radoszkowski were determined to be the most effective and stable pollinators, with an extremely high pollination frequency and obvious date rhythm.
Objective To evaluate the pollination characteristic on Chinese bellflower.
With flowering plants with only a small part of the self-pollination, the transfer of its pollen is usually dependent on certain pollinators.
A Study on the effect of bumble bee pollination to greenhouse tomato
The set percentage follow bees pollination were higher than that follow no bees pollination, insect pollination could reach to the effect of hand-cross-mix-pollination.
If the plants are "Cousins" or "siblings," they'd likely mature at the same rate because it's a way for "slowly maturing plants to improve their chances of cross-pollination."
This brings difficulty to the promotion of bumblebee pollination.
Climate change may be preventing bees from carrying out the vital job of pollination by upsetting their life cycles, a study has shown.
Reports of declining populations of bees and other flower-visiting creatures have raised concerns about pollination levels.
