Device for breaking dormancy of hard seeds of round leaf morning glories and method for promoting germination

Abstract

The invention discloses a device for breaking dormancy of hard seeds of round leaf morning glories, which comprises a hard seed friction box and an upper friction pressing plate. The invention also discloses a method for breaking the dormancy of hard seeds of round leaf morning glories and promoting germination, which comprises the following steps of: (1) selecting seeds; (2) putting the seeds into the friction box, and pressing the upper friction pressing plate used for covering heavy on the seeds for pushing and pulling back and forth to ensure that the seeds begin to germinate; and (3) carrying out a germination experiment on the hard seeds subjected to friction by using a paper-to-paper or grit germination method. The invention efficiently breaks the dormancy of the hard seeds of theround leaf morning glories through a physics friction method without any chemical reagent or hormone treatment. Compared with other physics friction methods, the invention does not damage the seeds, can reduce the hard seed rate to be less than 5 percentage after treatment from more than 80 percentage before treatment, and greatly improves the germination rate of the seeds. The invention has the advantages of ecological protection, simple method and lower cost.

Description

technical field [0001] The invention relates to a treatment device for breaking the hard dormancy of flower seeds and a method for promoting seed germination by using the device to treat seeds, belonging to the technical field of flower planting. Background technique [0002] Round-leaf morning glory (Pharbitis purpurea) belongs to Convolvulaceae, Petunia genus, and is an annual twining herbaceous plant. The whole plant is pubescent and slightly spreading bristles, the stems are several meters long, multi-branched; the leaves are alternate, the leaves are round-heart-shaped or broadly ovate-shaped, 3-14cm long, 2-13cm wide, usually entire , occasionally 3-lobed, with bristles on both sides, petiole length 1-10cm; flowers axillary, solitary or several in umbel cymes, pedicels 1-3cm long, sepals nearly equal in length, outer 3 ovate-elliptic, The two inner surfaces are linear-lanceolate, the diameter of the corolla is 4-6cm long, bucket-shaped, the flowers are red, purple, pi...

[0005] The application number is 200910133123.1 Chinese Invention Patent Application Publication, which discloses a method for breaking the hardness of leguminous seeds. The method uses concentrated sulfuric acid to dress the seeds, and then stirs and neutralizes them with strong alkaline salt solution or lye. This method requires a large amount of Acid and alkali, high treatment cost, safety and pollution problems, improper treatment will affect seed germination and seedling growth
