Controlling degradation requires understanding of many different phenomena, including chemical mechanisms, the influence of polymer morphology, the complexities of oxidation chemistry, and the effects of stabilisers, fillers and other additives.
How to Create a Pollinator Garden. Pollinators thrive on flower nectar and pollen. Designate a section of the landscape strictly for a pollinator garden filled with a multitude of grasses, trees, shrubs and wildflowers. Seek out a site that receives at least six hours of sun each day.
Flowering plants have several different parts that are important in pollination. Flowers have male parts called stamens that produce a sticky powder called pollen. Flowers also have a female part called the pistil. The top of the pistil is called the stigma, and is often sticky.Seeds are made at the base of the pistil, in the ovule. To be pollinated, pollen must be moved from a stamen to the stigma.When pollen from a plant's stamen is transferred to that same plant's stigma, it is called self-pollination.When pollen from a plant's stamen is transferred to a different plant's stigma, it is called cross-pollination. Cross-pollination produces stronger plants. The plants must be of the same species.For example, only pollen from a daisy can pollinate another daisy. Pollen from a rose or an apple tree would not work.eeds are made at the base of the pistil, in the ovule. To be pollinated, pollen must be moved from a stamen to the stigma.
