Causes of nectarine fruit cracking

It has been two or three days since August, and with the rise in temperature, nectarines have also begun to enter the market. Nectarine is one of the many peach varieties, and it is also the most popular variety in the market, but with the entry into the market, nectarine will also have some problems. Among them, fruit cracking is the most common problem of nectarine, which will seriously affect the quality of nectarine. So what on earth caused the nectarine to crack? Let's take a look.

1. Variety

There are many varieties of nectarine, and fruit cracking may be caused by variety factors. The degree and incidence of nectarine cracking are also different in different nectarine varieties, because nectarine cracking is different in size, but it is related to the cellular structure of nectarine peel. During the expansion period, the pericarp begins to become brittle, the pulp becomes soft, and the growth rate of the pericarp is not as fast as the pulp. According to the survey results, the peel is softer and thicker, and the varieties with compact structure have less fruit cracking. For example, the fruit cracking rate of Shuangxihong is only 11.5%. The varieties with thin and soft pericarp and loose structure have higher fruit cracking rate, for example, the fruit cracking rate of Zhongyou 4 is as high as 77.9%.

2. Climate

The climate leading to nectarine cracking is also a point that can not be ignored. Because entering the summer rainy season, the early and middle ripening nectarine varieties happen to be in the final expansion and maturity period, and the continuous overcast and rainy weather will make the nectarine physiology change. The adhesive cell ability of nectarine decreased and some soluble substances increased, which led to the softening of nectarine pulp, thinning of peach skin, softening of peach internal structure, slow growth rate of peel, unable to bear the expansion of pulp and formation of split fruit.

3. Soil

Soil is also one of the causes of fruit cracking, because nectarines need more nutrients for growth, and the absorption and transfer of nutrients start from the root. If there is a lack of certain elements in the soil, the nutrients in the soil will be out of balance, resulting in nectarine fruit cracking due to the lack of certain elements. For example, the lack of calcium in the soil, calcium is an important component of the plant cell wall, it can enhance the strength of the cell wall, if there is no calcium will make the cell wall resistance worse. Unable to withstand the pressure and extrusion of pulp cells, resulting in fruit cracking.

4. Management

Improper manual management will lead to external damage to the surface of the pericarp, burns of the pericarp, diseases and insect pests and drug damage will also lead to nectarine fruit cracking. Too long light time causes the pericarp surface to be dry and without moisture. Moreover, the fruit cracking is also related to the tree potential, and the tree age has a great relationship. The fruit cracking rate of the top fruit is higher, and the middle and lower end is lower.

These are the reasons why nectarines crack. When selecting and sowing nectarines, we should choose varieties with lower fruit cracking rate, such as Shuangxi Hongzhongyou 14, to strengthen the management of orchards. Do not blindly manage nectarines, nectarines are harmful to you but not good to you. If you want to know more about fruits, please continue to follow our pro-farm network.
