Abstract

The invention provides a method for increasing the germination rate of papaya seeds. The method comprises the steps of firstly selecting good-quality papaya seeds, then soaking the selected good-quality papaya seeds for 0.5 minute by using water with the temperature being 55 DEG C before carrying out pretreatment and sowing, and then sowing. The method provided by the invention has the advantages that the germination rate of the papaya seeds is increased to 93% for the first time; buds and seedlings are neat, the quality of seedlings is high, the problem of low germination rate or long germination time of the papaya seeds under the conventional condition is solved; the method is an improvement of the key technology for breeding of the papaya and a simple and practical method is provided for mass propagation of papaya seedlings; and the application range is wide, and complex treatment procedures are not needed for each planter in the papaya planting region before sowing.

Description

technical field [0001] The invention belongs to the field of plant planting and relates to a simple and practical method for improving the germination rate of papaya seeds. Background technique [0002] papaya( Carica papaya L. ), also known as papaya, milk melon, longevity fruit, is a tropical and subtropical evergreen cork large perennial herb, evergreen cork small tree, up to 8-10 meters, with latex; the stem is not branched or sometimes branched at the damaged site , with spirally arranged stipules. The fruit grows on a tree and looks like a melon, hence the name papaya. The milk of papaya is the main ingredient for making loose meat powder. Flowering and fruiting period throughout the year. [0003] Most papaya planting areas use real seeds to propagate and raise seedlings, but under natural conditions, the germination rate of real seeds is below 50%. When the external environment is poor, sometimes it can’t reach 10%, and the germination time is long, about 40 days...
