Problems solved by technology

The reason is that domestic researchers have found inconsistent results through research on the relationship between ethephon and plant resistance, that is, ethephon can both promote and inhibit the drought tolerance of plants, but the current research at home and abroad has not clearly revealed the effect The mechanism of action, therefore, limits the application of ethephon in improving drought tolerance to a certain extent

Embodiment 1

[0026] Embodiment 1 Ethephon solution seed soaking treatment

[0027] The seeds of two bluegrass species 'Midnight' and 'New Glade' were first sterilized with 1% sodium hypochlorite solution, rinsed with distilled water several times, and blotted dry. Then use 150mg / L ethephon solution to soak the seeds, sow the seeds for hydroponics, and compare with the control (the bluegrass grass without ethephon treatment) to comprehensively judge whether the drought tolerance is improved or not according to the data measurement based on the performance of the acreage. The drought treatment was induced by 30% PEG for 10 days. Sow the seeds after soaking in a seedling tray filled with vermiculite at a seeding rate of 15g / cm 2 , put the seedling tray on the water tank, and water it with a watering can every day before the lawn grows roots. When the lawn roots grow out, adjust the liquid level in the water tank so that the lawn roots are immersed in it, and add Hoagland nutrition. Replace i...

Embodiment 2

[0029] The optimization of embodiment 2 ethephon solution concentration

[0030] Use 150mg / L, 200mg / L, 300mg / L, 400mg / L, 600mg / L ethephon solution to soak the seeds of two bluegrass varieties 'Midnight' and 'New Glade' respectively, the soaking temperature The temperature is 25°C, and the soaking time is 24 hours. Tests of germination potential and germination rate Fifty seeds were treated with each gradient concentration and repeated 4 times. Place them in a petri dish with a diameter of 9 cm and three layers of filter paper at the bottom, keeping a certain distance between the seeds. . Put the petri dish in the plant incubator (luminous flux density 100μmol·(m 2 s) -1 , photoperiod 14h, 25 ℃, humidity 80%; Dark period 10h, 20 ℃, humidity 60%), measure the germination potential and germination rate of bluegrass together with the control group (the bluegrass without ethephon treatment) . The statistical results are shown in Table 1:

Abstract

The present invention relates to the application of plant growth regulator, specifically, provide the application of ethephon in improving the germination potential and drought resistance of bluegrass grass, it is characterized in that, utilize the ethephon solution that concentration is 100-200mg / L to Seed soaking of bluegrass to improve the germination potential and drought tolerance of bluegrass.

Description

technical field [0001] The invention relates to the application of a plant growth regulator, in particular to the application of ethephon in improving the germination potential and drought tolerance of bluegrass meadowgrass. Background technique [0002] Bluegrass (Poa Pratensis) is a perennial herb with fibrous roots, rhizomes, green leaves, good ornamental effect, rhizome reproduction, strong regeneration, pruning resistance, strong cold resistance, slightly poor drought tolerance, and A certain amount of trampling is very important for turfgrass and forage grass species. In the northern and central regions of my country, and in some cold and cool areas in the south, it is widely used for greening in parks, government agencies, schools, residential areas, sports fields and other places. Its characteristic is that it likes a cool and humid climate. In some parts of northern my country, it can maintain a long green period, which can meet the requirements of evergreen garden...
