Method for improving seed germination of coffea arabica

Abstract

The invention discloses a method for improving seed germination of coffea arabica. The method comprises the following steps that 1, aspergillus niger is cultured; 2, after green coffee beans are degummed with an aspergillus niger culture solution, the green coffee beans are dried in the shade; 3, endocarp of coffee beans is removed; 4, the coffee beans of which the endocarp is removed are put into a hydrogen peroxide solution of which the volume fraction is 1% to be disinfected for 30 min and then fished out and washed with clear water three times; 5, the coffee beans which are washed with the clear water are put into gibberellin of which the mass fraction is 0.02% to be subjected to seed soaking for 24 h, and then seeding is conducted. By adopting related means of microbial pectase degumming, endocarp removing before seeding and the like in the seed production process, the seedling emergence time of coffea arabica is shortened, seedling emergence can be achieved within about 50 days, and the seedling emergence rate of coffea arabica seeds is increased and can reach 70%.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a method for improving the germination of coffee arabica seeds. Background technique [0002] Coffea arabica is an important economic crop in the tropical area of ​​Yunnan. Seedling cultivation is an important link in the agricultural production of argentina, and the germination of seeds determines the efficiency of Coffea arabica seedling cultivation. Clean water or chemical reagents are usually used for degumming in the process of seed production of coffee arabica seeds. Water degumming is often not complete, and the seeds show residual pectin, which makes the seeds prone to mold during germination; chemical degumming is too strong, which is easy to cause damage to the seeds; and hard The endocarp wraps the seeds and hinders seed germination. These factors lead to low seed germination efficiency in conventional seedling cultivation methods. Contents of the invention [0003] In o...
