"Picking fruit according to gender" is purely a folk experience Fruit regardless of male and female

The umbilical orange tree does not exist as a mother, and the fruit naturally does not exist as a mother."According to

Mother-in-lawto choose fruit is a trick that many citizens have heard of, especially when choosing oranges, pears, watermelons, peaches and other fruits, this method seems to help us choose more delicious fruit. Is the fruit really male and female? Is it effective to choose fruits that taste better? What factors determine the taste of fruit? Experts in an interview with reporters, said that most of these methods are people's life experience, in fact, fruit does not exist male and female, but through some of the external characteristics of the fruit to determine its internal quality of the practice has a certain scientific basis.Fruit has no male-female division according to the male-female fruit, through certain appearance characteristics of the fruit to determine the sex of the fruit, especially in the selection of umbilical orange, watermelon and other fruits, this is reliable? Peng Liangzhi, deputy director of the Citrus Research Institute of the Chinese Academy of Agricultural Sciences, told reporters that the umbilical orange tree does not exist as a mother-in-law, and the fruit naturally does not exist as a mother-in-law. Jia Wenlock, head of the fruit tree department of the School of Agomy and Biotechnology of China Agricultural University, said that in fact, not only umbilical oranges, including peaches, watermelons and all fruits do not exist male and female, this is only a comparative image of people's appearance of different fruits, is the experience of people's lives, there is no scientific basis.the open and closed umbilical cord of the navel orange is caused by the development process according to the popular method of selecting fruit, to the navel orange as an example, many people think that the orange with "
is
"
member orange
"
, the taste is better. The umbilical cord is smaller and protruding for
"
male orange
"
, the taste is relatively poor. In this regard, Peng Liangzhi said, people according to the size of the orange umbilical cord depression or not to determine the orange mother-in-law method has no scientific basis."
Generally speaking, we call the orange protruding from the umbilical cord open umbilical cord, the umbilical concave into the can be called closed umbilical cord, the size of the umbilical cord is mainly due to the different varieties of fruit trees and the different degree of growth and development of secondary fruit, and the appearance of open umbilical cord and closed umbilical cord is mainly due to the size of the umbilical cord (secondary fruit) and the main fruit on the secondary fruit package range is different, and can not therefore determine the fruit's mother
"
, Peng Liang told reporters.jiawen lock explained that the reason why there is a difference between open and closed umbilical cord, in fact, with the plant room, different plant sub-room has different characteristics, the fruit after development there is a difference in appearance, but this can not become the basis for determining the fruit mother.To take peaches as an example, from the appearance, some peach skin parts have ditches, some do not, this is actually related to the plant's sub-room, the fruit is not developed, the sub-room is composed of several parts, different fruit tree varieties and different environment, climate, etc. will have different effects on the development of the plant, this effect is on the appearance of the fruit, and will not affect the fruit's so-
called
"Flowers are different from males and females, not the same as the difference between the sexes of the fruit fruit does not exist male and female, people sum up the male mother and biological sense of male mother is not the same. Jia Wenlock introduced, fruit tree flowers do exist male and female, from a biological point of view, pollen is male, children are female, some flowers for the sexes, that is, the central sub-room has a column head, surrounded by a circle of wreaths, the sac-shaped part of the top of the flower is flower medicine. There are some flowers only children and no flower medicine, these are female flowers, accordingly, only flower medicine and no children's room flowers for male flowers,
"
from this point of view, it is clear that flowers are female and male.
”Does the division of flowers mean the part of the mother-in-law after growing up as a fruit? Jia Wenlock told reporters that there is no inevitable link between the two. The fruit we eat is actually the fruit of the plant, the fruit is developed by the sub-room walls, which contain seeds, therefore, we can not divide the fruit out of the mother-in-law.Hot Question
:
Fruit taste is determined by genes Since fruit does not exist male and female, there is no scientific basis for the method of selecting fruit, which factors determine the taste of fruit?: Fundamentally, the taste of fruit is determined by genes, some genes can control the sweetness of the fruit, some can control the acidity of fruit, these genes exist in different places. From this point of view, the taste of the fruit is determined by its molecular basis, the molecular basis of fruit quality is currently the main research content worldwide.Peng Liangzhi: Take umbilical orange as an example, citrus fruit general fruit top part of the sugar content is higher, fruit base (ti) part is lower, therefore, secondary fruit sugar content will be higher, taste better. In general, the reasons for determining flavor mainly include varieties, tree age, fertilizer, climate and so on.Tip
:
through the appearance of picking fruit has a certain scientific reporters visited several fruit supermarkets to learn that many customers have heard of this according to
mother-in-law
"
to pick fruit method, and some people reflect to reporters that the fruit picked out in this way is often sweeter, better taste. In this regard, Jia Wenlock explained to reporters, according to the mother-in-law selection of fruit methods have no scientific basis, but according to some of the appearance of fruit characteristics of the selection method has a certain scientific."
the taste and water content of a fruit is often related to some of its appearance characteristics. In the case of umbilical orange, for example, the appearance of the open or closed umbilical cord is related to the amount of sugar in the fruit, and for other fruits, the thickness of the peel is different, the taste will be different. But many of the methods used to judge the inward quality through the external characteristics of fruit are mostly the experience accumulated in people's lives.
