Embodiment Construction

[0010] The flowering induction method of annual konjac bulbs comprises the steps of selection of konjac bulbs, growth regulator soaking and spraying, as follows:

[0011] A. the konjac tissue culture seedling cultivated with CN991210514 method goes out bottle in April, presses the planting of the specification of 10cm * 10cm, konjac tissue culture seedling production is carried out according to CN991210514 method, harvests in November of that year, selects the annual corm of 150 grams for use at 20 ℃ ± 2 for dark storage;

[0012] b. Soak the corms with the plant growth regulator gibberellin 100ppm solution for 1 hour until March of the next year, take them out and dry them in the shade, and plant them in flower pots after a week;

[0013] When c treats that corm top bud grows to 5cm, spray with plant growth regulator gibberellin 1ppm liquid, the annual konjac corm promptly blooms in May. The stamens and pistils of Amorphophallus konjac are normal, which can be used as the pa...

Abstract

The invention relates to an annual konjac corm flower-formation induction method and belongs to the technical field of the agriculture biology, which comprises a selection of the konjac corm, immersion of the growth adjusting agent and spraying procedures; a. the konjac corm tissue cultured seedling is moved out of the bottle in April, and is planted in the specification of 10 cm multiplied 10 cm, and is harvested in November then; 150 grams of annual corm is selected to be stored in dark under the temperature of 20 DEG C minus or plus 2; b. in March next year, the corm is immersed in a plant growth adjusting agent-gibberellin 100ppm for one hour, and is taken out for drying, and is planted in a flower pot one week later; c. when the top bud of the corm is grown to 5 centimeters, the corm is sprayed with 1 ppm plant growth adjusting agent-gibberellin, thereby the annual konjac corm is flowered in May. Compared with the prior art, the invention has the advantages that the flowering of the konjac corm is earlier and the living period of the konjac is shorter, which establishes a foundation for accelerating the konjac system classification research and the hybrid breeding work.

Description

Technical field: [0001] The invention relates to a method for inducing flower formation of annual konjac bulbs, which belongs to the field of agricultural biotechnology. Background technique: [0002] Konjac is a perennial herbaceous plant. Usually, it takes 4-5 growth cycles from sowing to transform from vegetative growth to reproductive growth, flower and bear fruit, and complete the life cycle. Because the flowering time is too long, it affects the progress of konjac taxonomy research and cross breeding work, and brings great difficulties to konjac cross breeding and the observation and selection of offspring. There have been many reports and achievements on other plants to induce flowering and regulate female and male flowers with exogenous growth regulators, shorten the life cycle of plants, and make them flower and bear fruit earlier. Sun Mingyuan of Southwest University and others used three-year-old konjac bulbs to do some research and discussion on the flower-attra...
