The Feijoa sellowiana Berg. belongs to the family Myrtaceae. This is a subtropical plant native to South America. Nevertheless, it has been grown to some extent in Florida and California with intermittent plantings of one to two acres of land. The plant Feijoa is best planted when the temperature is mild or moderate having thirty to forty inches of rain in one year. The fruit product is being made deliciously as jam or jelly. It can also be consumed raw or stewed. A science expert on this plant has mentioned that nine year-old Feijoa plants can generate fruit at the rate of ten thousand pounds for every acre and such rate is not the optimum production. It has different shapes and can have fifteen to eighteen feet height. The fruit is colored dull green with a whitish bloom, and its color can be enhanced better when viewed by means of microscopy using the stereo binocular microscope. It can be oval, oblong or round in form and has length of one to three inches. The minute details of the fruit can be magnified via microscopy under the stereo binocular microscope. The skin of the fruit is thin and is being coated with whitish granular flesh approximately one-fourth thick enclosing a translucent like jelly pulp where twenty to thirty pieces of tiny seeds are embedded. Such seeds can be viewed better with the aid of microscopy using the stereo binocular microscope. The aroma of the fruit is enchanting, and its flavor implies pineapple or strawberry, which is why the fruit is at times known as pineapple guava. Technically, the plants are in fifteen to eighteen feet apart. In order to have excellent production, irrigation is recommended.

According to a science expert, the handsome flower is one and a half inches in diameter having fleshy cupped petals that are safe to be consumed. The flowers are colored white on the exterior part, and purple in the interior portion. The stamens develop a prominent crimson tuft at its core having an extending stigma on top of the stamens as observed better under the microscope such as stereo binocular microscope. The stamens are commonly stiff and long.

Based on the studies of the science experts, they have observed that certain plants are self-sterile while others are self-fertile, nevertheless, even the self-fertile plants could not pollinate on its self. An initial test or experiment was performed by a science expert, and he discovered that among these plants, six various seedling plants were self-sterile. Another science expert had uncovered one cultivar that obviously needed not the process of cross-pollination. Nonetheless transmission of pollen inside the flower was needed. Feijoa has the propensity toward self-sterility.

Birds that feed on the petals, which could be safely eaten, in their native habitation turned dusted with pollen from the tuft of anthers. Further, when these birds visited another flower they influenced the cross-pollination. It was deemed that transmittal of pollen among the plants either through insects or man was necessary.
Honeybees were the only type of insects that took time to visit the flowers. They only obtained pollen and did not get any nectar as observed via microscopy using the stereo binocular microscope. Those plants that were screened in order to avoid the bees from coming to them set only nine percent of the flowers, while those plants visited by the bees set forty percent of their flowers.
Feijoa is pollinated by the insects mainly be the bees, and that majority of the cultivars display markedly enhanced fruit set when cross-pollinated.
The proof suggests that plants should be pollinated by the bees except when the appropriate genuses of birds are obtainable. Zero suggestions on procedures of utilizing bees have been performed. Be supposed to the acreage elevate the appropriate utilization of bees would no doubt be important.Read more on this topic
