Question 2: What are the common nutritional reproductive organs of garlic? vegetative propagation
The reproductive mode in which vegetative organs (roots, leaves and stems) of plants produce new individuals is called vegetative reproduction. For example, the creeping branches of strawberries and the leaves of begonia can germinate, and these buds can form new individuals. Vegetative reproduction is a kind of asexual reproduction.
Garlic breeding model
Garlic can be used for seed propagation and bulb meristem propagation.
(1) The fruits of wild plants propagated by seeds are harvested in early and middle July, harvested, dried and threshed for later use. At the same time, fertile and loose land is selected as the high border, with the width of 1.3 ~ 1.5 m, furrowing or sowing in the flat border, covering soil 1 cm, watering, and covering with grass curtain or plastic film. You can also plant seeds in spring or autumn. The method is as above.
(2) Bulbs can be propagated in spring and autumn. Wild plants are excavated in the field, and small bulbs without disease and damage are selected as propagation materials. In the pre-made border, make horizontal ditches with row spacing of 10 cm, sow 40-50 seeds per row, cover with soil and compact.
Question 3: garlic is usually propagated with garlic cloves, which belongs to answer C.
Garlic cloves are the roots of plants, and roots belong to vegetative organs, so propagation with garlic cloves is vegetative propagation.
Question 4: Can garlic be propagated with seeds? Garlic seeds can reproduce, but the reproductive effect is not as fast as that of directly inserting garlic cloves into the soil. Garlic propagated by seeds grows slowly and takes up land for a long time, so this method is rarely used in production.
Question 5: Farmers often plant garlic cloves to reproduce garlic, which is the same as the reproduction method of which of the following organisms. Answer c
Analysis: This topic examines the asexual reproduction of plants. Asexual reproduction refers to the reproductive mode without the combination of bisexual germ cells, such as cutting, grafting, tissue culture and so on.
A: The way plants reproduce with vegetative organs such as roots, stems and leaves is called vegetative reproduction. When strawberries, potatoes and deciduous leaves take root and propagate, new individuals are directly produced by the mother, and the combination of bisexual germ cells is not needed. This kind of reproduction is called asexual reproduction. Vegetative reproduction is the most common way of asexual reproduction. Common ways of asexual reproduction are cutting, grafting and layering. Farmers often plant garlic cloves to breed garlic, that is, using stems.
So choose: C.
Comments: Asexual reproduction is a common way of plant reproduction, which can be compared with sexual reproduction.
