Problems solved by technology

Due to the short lifespan of seeds, low germination rate, and high rate of reproductive variation, it is difficult to obtain seedlings with consistent traits by sowing and propagation, and cannot be used in large-scale production; while branch propagation has a low propagation coefficient, which is easy to degenerate and spread diseases, and also Not suitable for modern mass production
Therefore, the defect that the propagation method of existing gerbera seedlings exists is: propagation speed is slow, seedling variation rate is high, character is inconsistent, growth is not vigorous

Embodiment 1

[0013] The rapid propagation method of gerbera cut flower seedlings of the present invention mainly comprises the following steps:

[0014] (1) Get the flower buds whose pedicel length is 1cm, take out the flower buds after being sterilized in 0.1% mercury liter solution for 12 minutes, and rinse them with sterile water for 7 times;

[0015] (2) cutting the receptacle part of the described flower bud after the disinfection treatment as the explant;

[0016] (3) The explants were cut into small pieces of 3 mm and placed on the induction medium, and cultured under the conditions of light intensity of 1000 Lux and temperature of 22° C. to induce adventitious buds on the explants. The induction medium is MS medium;

[0017] (4) When the adventitious buds to be induced grow to 3 leaves and the leaves are about 3 cm in length, cut off the adventitious buds and place them on the proliferation medium, under the condition that the light intensity is 1500Lux and the temperature is 22°C...

Embodiment 2

[0022] The rapid propagation method of gerbera cut flower seedlings of the present invention mainly comprises the following steps:

[0023] (1) Get the flower buds whose gerbera pedicels are 3cm long, take out the flower buds after being sterilized in 0.1% mercuric solution for 12 minutes, and rinse them with sterile water for 8 times;

[0024] (2) cutting the receptacle part of the described flower bud after the disinfection treatment as the explant;

[0025] (3) cutting the explants into 5mm small pieces and placing them on the induction medium, cultivating them under the condition that the light intensity is 1000 Lux and the temperature is 28°C, and inducing the adventitious buds to be produced on the explants, The induction medium is MS medium added with AKT2.0PPM, NAA0.2PPM, BA1.0PPM, and IAA0.5PPM;

[0026] (4) When the adventitious buds to be induced grow to 4 leaves and the leaves are about 4 cm in length, cut off the adventitious buds and place them on the proliferat...

[0031] The rapid propagation method of gerbera cut flower seedlings of the present invention mainly comprises the following steps:

[0032] (1) Get the flower buds whose gerbera pedicels are 2cm long, take out the flower buds after being sterilized in 0.1% mercury liter solution for 12 minutes, and rinse them 8 times with sterile water;

[0033] (2) cutting the receptacle part of the described flower bud after the disinfection treatment as the explant;

[0034] (3) cutting the explants into 4mm small pieces and placing them on the induction medium, cultivating them under the condition that the light intensity is 1000Lux and the temperature is 25°C, and inducing the adventitious buds to be produced on the explants, The induction medium is MS medium added with AKT1.0PPM, NAA0.1PPM, BA0.5PPM, and IAA0.3PPM;

[0035] (4) When the adventitious buds to be induced grow to 4 leaves and the leaves are about 4 cm in length, cut off the adventitious buds and place them on the proliferat...

Abstract

The present invention discloses the fast germchit propagating method for flameray gerbera cut flower, and aims at providing one kind of fast propagating method of flameray gerbera germchit with less germchit variability, consistent characteristic and robust growth. The method includes cutting the floral receptacle of flameray gerbera bud as the explant, cutting the floral receptacle into small blocks, culturing in inducing culture medium at proper lighting and temperature to grow indefinite bud, culturing the indefinite bud in proliferating culture medium at proper lighting and temperature to grow bush bud, cutting the bush bud into single seedlings, culturing the seedlings in rooting culture medium at proper lighting and temperature to induce rooting, and finally transplanting the rooted seedling in seedling bed. The present invention is applied in propagation of flower.

Description

technical field [0001] The invention relates to a method for rapid propagation of gerbera cut flower seedlings. Background technique [0002] Gerbera jamesonii Bolus, also known as gerbera and sunflower, is a perennial herbaceous plant. It is a hot-selling flower and potted famous flower at home and abroad. Gerbera flowers are huge and can be used in rich and bright colors. They can be used as ideal materials for gift bouquets, flower baskets and artistic flower arrangements, and can also be used as important decorations for high-end occasions. The traditional propagation method of gerbera is by sowing or branching. Due to the short lifespan of seeds, low germination rate, and high rate of reproductive variation, it is difficult to obtain seedlings with consistent traits by sowing and propagation, and cannot be used in large-scale production; while branch propagation has a low propagation coefficient, which is easy to degenerate and spread diseases, ...
