Embodiment 1

[0041]This example provides an induction medium for inducing flowering of Dendrobium nobile and a culture method for artificially inducing flowering of Dendrobium nobile.

[0042] The induction medium for inducing the flowering of Dendrobium dendrobii comprises MS basal medium and the composite plant inducer added in the MS basal medium, and the composite plant inducer includes 0.5mg / L naphthaleneacetic acid, 0.5mg / L furfuryl aminopurine, 1.0mg / L phenyl thiadiazolyl urea.

[0043] The culture method of described artificial induction dendrobium dendrobium flowering comprises the steps:

[0044] S11. material selection: select the strong seedlings of Dendrobium dendrobium with good growth;

[0045] S12. Induction stage: inoculate the robust seedlings of Dendrobium nobile selected in step S11 in the induction medium for inducing the flowering of Dendrobium nobile, and cultivate them under the conventional culture conditions of light time 17h / day, and after 50 days, more than 90%...

Abstract

The invention discloses a culture method for artificially inducing blossom of dendrobium pulchellum and an induction culture medium. The culture method for artificially inducing blossom of dendrobiumpulchellum comprises the following steps: acquiring healthy dendrobium pulchellum seedlings; putting the dendrobium pulchellum seedlings in an induction culture medium, performing induction culture treatment until blossom buds grow out from the dendrobium pulchellum seedlings; and transplanting the dendrobium pulchellum seedlings growing out flower buds to a flowering culture medium, and performing flowering culture treatment. The induction culture medium comprises a basic culture medium and a compound plant inducer which is added into the basic culture medium, wherein the compound plant inducer is prepared from at least two of naphthylacetic acid, furfurylaminopurine and thidiazuron. The culture method for artificially inducing blossom of dendrobium pulchellum can artificially control theblossom time and blossom cycle of dendrobium pulchellum, and the dendrobium pulchellum has complete floral organs, no deformed flower and durable flowering phase.

Description

technical field [0001] The invention belongs to the technical field of plant tissue culture, and in particular relates to a culture method for artificially inducing flowering of Dendrobium nobile and an induction medium for inducing flowering of Dendrobium nobile. Background technique [0002] Dendrobium is a perennial epiphytic herb with 1500-1600 native species in the world, widely distributed in tropical and subtropical Asia to Oceania. Dendrobium plants have various flower colors, bright colors, long-lasting flowering period, and most species have aroma, which has excellent ornamental effect. Dendrobium pulchellum is a large Dendrobium plant mainly produced in India, Nepal, Thailand, Vietnam and other places. The adult plant can reach a height of 120cm. It blooms in late spring and early summer. The petals are light milky yellow or light pink, with fluff on the lips, large symmetrical brown-red spots, and elegant floral fragrance. It is deeply loved by the public. Unde...
