Method for improving iris lactea seed germination rate

Abstract

The present invention discloses a method for raising germination percentage of sweet iris seeds. Said method includes the following steps: firstly, soaking sweet iris seeds in auxin, gibberellin or potassium nitrate solution, then taking out the sweet iris seeds from said solution and placing the sweet iris seeds into a day-and-night temperature variable and dark environment to make germination. At day, it uses 2.5-30deg.C temperature to make treatment for 6-12hr, and at night it uses 15-20deg.C temperature to make treatment for 12-18hr.

Description

technical field [0001] The invention relates to a method for increasing the germination rate of seeds, in particular to a method for increasing the germination rate of horse rind seeds, and belongs to the field of garden plants. Background technique [0002] Iris (Iisensata Thunb) is a perennial herbaceous plant of the family Iridaceae and the genus Iris. The plants are low, densely clustered, and the rhizomes are short and strong. It is naturally distributed in Heilongjiang, Jilin, Liaoning, and Inner Mongolia. It likes to grow in semi-shady or humid environments, but it can also grow well in sunny and dry land, with strong adaptability. Under the low temperature condition of extreme temperature -36 ℃, it can survive the winter safely without taking any cold protection measures. It can grow on barren and dry sandy land, and it can also grow, bloom and bear fruit normally on mild or moderate salinized soil. ;Exhibits strong saline-alkali tolerance, is the construction gras...
