What is a berry?
At home berry refers to any small fruit with a juicy pulp: these include cherries, strawberries, raspberries, rose hips, although from a Botanical point of view they are not. So, rosehips, and strawberry is a false berry, raspberries – it's a drupe. While larger fruits are rarely associated with berries, although they may be considered in botany: it is a tomato, eggplant, kiwi.
Berry is the fruit with a thin skin, many seeds with a hard seed skin, juicy mesocarp. The berries develop from the top and bottom of the ovaries in some cases on top of them withered remains of the perianth (currants).
False berries are called such fruits, which have the same structure, but are not formed from the ovary but from other parts such as a receptacle.
It is widely believed that watermelon, despite its size, is a berry. In structure the fruit of the watermelon really meets all criteria: has a juicy pulp, many seeds with a hard shell, solid and relatively thin skin. But still some differences it has, which botany will carry him to the berries. Watermelons are tiquina with similar morphological features, but some significant differences.
Tiquina are formed of the lower ovary and are composed of three carpels. They are polyspermous, as the berries, but the seeds in each of them. They also have a different structure of the pericarp: they are too hard compared to berries, the outer layer a meaty middle layer and a soft inner. Tiquina can grow to large sizes, the berries are always smaller.
Due to the fact that the melon has a more firm flesh, it is not called berries, though these fruits in structure is almost identical to a watermelon. This is also tiquina: they have a huge amount of seeds, very dense, hard shell and a fleshy middle layer. Takinami are many other fruits which in everyday life can be named differently: for example, cucumber is also tiquina.
There is a simple way to determine whether the fruit of the melon or not: you need to know to which family the plant belongs. All members of the gourd family give not the berries, and tiquina.
Tiquina call godavitame fruits because of the similarity with berries, also from the berries is to distinguish the apples. From a Botanical point of view the so-called agodavid multi-seeded fruits of plants of the family Apple trees: quince, pear, cotoneaster, mountain ash. Unlike tiquina or berries they have a leathery core which contains the seeds, and the skin is very thin.
Advice 2: Why is there no ovaries
It often happens that gardeners perform all necessary agro-technical measures, looking forward to the appearance of the ovaries, but they are not. What is the reason for the appearance of the empty shell?
If your cucumber patches no ovaries, keep in mind that the delay of the appearance of female flowers may lie as seed. If you sow fresh seeds, the first formed male flowers and then female. Use for sowing the seeds 2-3 years ago. While both female and male flowers will be formed at the same time.
Another cause of infertility in cucumbers is imbalance of power. For example, the presence in the soil excessive amounts of nitrogen fertilizers, which causes rapid growth of leaves, vines and barren flowers.
The third reason for the lack of female flowers - watering cold water below 25°C. should Not be allowed, that the water was colder than the soil.
Another factor in the emergence of "pustovetov cucumber abundance" – too much moisture in the soil. Dry the cucumber on her bed for several days. As soon as a little podvinut the leaves immediately and there will be many female flowers. Try not to overdry soil.
Presidnete the top of the main stem of plants. It will stop their growth in length and cause emergence of lateral shoots, female flowers.
Problems with the ovary on tomatoes can occur if too high a temperature and not enough moisture. One of the reasons may be a lack of phosphorus and cobalt in the soil. Use special drugs to increase the number of ovaries, which are sold in specialized stores. Tomatoes don't like overly fertilized soil - all growth goes to the tops.
If the ovary is not formed on the cabbage seedlings might have suffered freezing temperatures or were planted too early. Can be an adverse influence of heat, low humidity. Try drugs a Germ, cabbage or Amberin" – used for plants in stressful situations. Choose varieties of Dutch selection, they have problems with the formation of the ovary is not observed.
