Embodiment 1

[0014] Example 1 Synthesis of gibberellin rare earth complex

[0015] (1) Preparation of rare earth chloride: RE 2 O 3 (RE=La 3+ , Ce 3+ , Sm 3+ ) was dissolved in a slight excess of 1:1 hydrochloric acid, and an appropriate amount of H was added. 2 O 2 Accelerate the dissolution, after the dissolution is complete, slightly heat to make the residual H 2 O 2 Completely decomposed, evaporated under reduced pressure and concentrated to a large amount of crystals to separate out, suction filtered and recrystallized 3 times, the resulting crystals are in P 2 O 5 Dry in desiccant until constant weight, measure RE by EDTA titration 3+ , Determination of Cl by silver method - , the water of crystallization was measured by thermogravimetric method, and it was confirmed that the crystalline composition was RECl 3 ·6H 2 O.

[0016] (2) Preparation of gibberellin rare earth complex: Measure RECl according to chemical formula 3 ·6H 2 O:GA 3 =1:3 Weighing, dissolving rare ea...

Embodiment 2

[0018] Example 2 Gibberellin lanthanum complex [La(GA 3 ) 3 ·2H 2 O] Induces flowering in Astragalus

[0019] (1) In Yulin, Guangxi, select 5-month-old vine plants that grow robustly and have the ability to form flowers and fruits, chase once farmyard manure, and cultivate and manage according to conventional practices.

[0020] (2) In the stage from the beginning of flower to the beginning of young fruit development, 10-20 μmol / L of gibberellin lanthanum complex [La(GA 3 ) 3 ·2H 2 The O] solution was sprayed on the whole plant of the vine, and the spraying amount was suitable for the droplets on the leaves, and sprayed once every 10 days. The results showed that gibberellin-lanthanum complexes could produce 5-8 multi-female flower inflorescences per branch, and each inflorescence had 5-10 female flowers.

[0021] La(GA 3 ) 3 ·2H 2 The concentration of O can be 10 μmol / L, 11 μmol / L, 12 μmol / L, 13 μmol / L, 14 μmol / L, 15 μmol / L, 16 μmol / L, 17 μmol / L, 18 μmol / L, 19 μmol / L...

Embodiment 3

[0022] Example 3 Gibberellin cerium complex [Ce(GA 3 ) 3 ·2H 2 O] Induces flowering in Astragalus

[0023] (1) In Yulin, Guangxi, select 5-month-old vine plants that grow robustly and have the ability to form flowers and fruits, chase once farmyard manure, and cultivate and manage according to conventional practices.

[0024] (2) From the beginning of flower to young fruit development stage, use 10-20 μmol / L of gibberellin cerium complex [Ce(GA) 3 ) 3 ·2H 2 The O] solution was sprayed on the whole plant of the vine, and the spraying amount was suitable for the droplets on the leaves, and sprayed once every 10 days. The results showed that the gibberellin-cerium complex could produce 5-8 multi-female flower inflorescences per branch, and each inflorescence had 5-10 female flowers.

[0025] Ce(GA 3 ) 3 ·2H 2 The concentration of O can be 10 μmol / L, 11 μmol / L, 12 μmol / L, 13 μmol / L, 14 μmol / L, 15 μmol / L, 16 μmol / L, 17 μmol / L, 18 μmol / L, 19 μmol / L, 20 μmol / L.

Abstract

The invention discloses a method for inducing plukenetia volubilis to bloom. Plukenetia volubilis is a perennial wood vine oil plant of Euphorbiaceae, and plukenetia volubilis oil squeezed from seeds of the plukenetia volubilis is rich in polyunsaturated fatty acids such as alpha-linolenic acid, alpha-linoleic acid and oleic acid and has wide application prospects in the fields of food, medicines, cosmetics and the like. However, plukenetia volubilis planted in the southeast region of Guangxi Guangxi cannot bloom normally. According to the method, a gibberellin rare earth complex is synthesized and prepared into a 10-20 [mu] mol / L solution, the solution is sprayed to the whole plukenetia volubilis from the initial flowering stage to the young fruit development stage, the spraying amount is appropriate when liquid drops appear on leaf surfaces, and the solution is sprayed once every 10 days. According to the method provided by the invention, plukenetia volubilis plants can be induced to bloom, each branch generates 5-8 inflorescences with multiple female flowers, and each inflorescence has 5-10 female flowers. The method is simple and convenient to operate, low in cost and remarkable in flower promoting effect, can remarkably promote flowering of plukenetia volubilis, and has a good application prospect.

Description

technical field [0001] The present invention relates to a method for plant tissue culture, in particular to a method for inducing flowering of Astragalus chinensis. Background technique [0002] Plukenetia volubilis L., also known as Plukenetia volubilis L., is a perennial woody vine oil plant belonging to Euphorbiaceae, also known as Plukenetia volubilis L., which is rich in α-flax. Polyunsaturated fatty acids such as acid, alpha-linoleic acid and oleic acid are considered as high-end vegetable oils and have broad application prospects in the fields of food, medicine and cosmetics. [0003] Currently in Yunnan, Guizhou, Guangxi, Hainan and other provinces and regions vigorously develop the Astragalus vines industry, but the Astragalus parsnips planted in the southeastern part of Guangxi cannot bloom normally, which affects the development of Astragalus parsnips industry. Star oil vine is a raceme with monoecious dioecious flowers. The ratio of male and female flowers on ea...
