As the saying goes: there must be a devil in everything that goes wrong! In the public's customary understanding of these fruits with seeds suddenly no seeds, so the community began to rumors, said what "not with the seeds of the fruit must not be eaten! Either with a touch of contraceptive pills, or genetically modified, people eat will be infertile!" And so on. These seedless fruit "mutation" of the words out, coupled with the blackmail, really affects a lot of people's understanding of the seedless fruit, consumers do not dare to buy, do not dare to eat, farmers do not dare to plant!
So, what is the situation? Seedless fruit is not the use of contraceptives? Is it genetically modified? People consume in the end there is no harm to the body? Today, we will talk to you about this issue: first of all, we will talk about the relationship between fruit and seeds, and then we will talk about the past and present life of seedless fruits, and finally we will talk about the most concerned about the problem - people consume seedless fruits on the body in the end there is no harm!
One, what is the relationship between fruit fruit and seeds? Seedless fruits really do not have seeds?
In everyone's common sense, crops are sown by the seed growth, fruit fruit is developed from the crop ovary, fruit in the seed child and by the ovary ovule development and growth out of the (ovules contained in the ovary). So the question arises: how can a fruit grow a crop and produce fruit, since it has no seeds?
Not really! Many people may not know, the crop body has a variety of very small amount of plant hormones (or called endogenous plant hormones), including growth hormone, gibberellin, cytokinin, abscisic acid, ethylene, these hormones directly affect and regulate a variety of physiological functions of the crop and the various aspects of the growth process, the fertility of the crop plays an irreplaceable regulatory role. It can be said that the crop germination, rooting, flowering, fruiting, maturation and other aspects of fertility, are closely related to the body's own types of hormones. Among these hormones, growth hormone and gibberellin directly affect the development of seeds in the fruit.
The fruit is grown from the ovary and the seed is grown from the ovule. We usually eat seeded fruits are actually a kind of angiosperm, angiosperms have ovaries and seeds, and the pulp that we eat is actually the ovary, and the fruit seeds that we spit out are the seeds. Crops in order to reproduce and self-protection, in the process of fruit growth and development, the fruit outside the ovary as if the quilt to protect the seeds inside, and the seeds in the process of development will in turn generate fruit growth hormone and gibberellin, in order to promote the ovary cell walls continue to divide, elongation, thus promoting the development of the fruit continues to expand.
So, even in the case of incomplete development of ovules, but as long as the growth hormone and gibberellin is sufficient, the ovary is still able to develop normally, and the fruit can still develop normally. Because in the crop after flowering, it can synthesize enough growth hormone and gibberellin self-supply, no longer need external growth hormone or pollen stimulation, can continue to grow fruit, just this fruit within the seed development is incomplete or no obvious or seed just! However, because there are no seeds, if one wishes to continue to grow these fruit crops, they can only be cultivated by grafting or taking cuttings.
In this regard, seedless fruits are not really seedless, but rather the seeds do not develop into seeds or are artificially regulated by plant hormones so that the seeds do not develop and grow!
