This is one of the main propagation methods of gladiolus, that is to say, propagation in separate spheres. After the gladiolus is planted, new bulbs will be formed at the place where the mother ball sprouts. As the new ball grows up, a lot of sub balls will be formed between the new ball and the mother ball. The large sub ball has a diameter of more than 1cm. After cultivation, it will bloom in the same year. The small sub ball is as big as the mung bean, and it will bloom in one or two years after cultivation. When flowering in October to November, the stem ball rises, according to its size, the old ball will not be left, leaving the new ball and the sub ball, for full airing, and then stored in a temperature of 5-10 ℃ ventilated dry place, the second year can be seeded.
If the number of seed balls is small, they can be cut and reproduced. Remove the outer membrane of the big bulbous, and cut the bulbous into several pieces after being sterilized with a sharp knife. When cutting, pay attention to take more than one stem bud and stem plate on each piece. In order to prevent rotting, we can use the plant ash and charcoal powder to smear the stem plate. After drying, the stem buds are loaded into the culture soil upward, with a depth of 5-10cm.
Gladiolus seed ball is no dormancy period, Ru fruit will crack when it is mature, to timely harvest seeds, because its life is relatively short, so after harvest, it should also be timely seeded, generally in the middle of September or the first ten days of sowing, the temperature is best kept at ℃, a month or so can be seeded.
Dormant bud, axillary bud and bulb can be used as explants. After disinfecting and inoculating, they can be cultured at 25 ℃, using induction, subculture and rooting culture to obtain seedlings, continuing to cultivate seedlings to obtain small bulbs. After two years of planting, they will grow into mother balls, and they are non-toxic.
The above is a summary of several Gladiolus breeding methods, I hope to help you.
