Does Parthenocissus tricuspidata Have Seeds?
As a star plant in the field of vertical greening, Parthenocissus tricuspidata has become the preferred choice for building facade beautification due to its strong climbing ability. The propagation method of this plant, seed cultivation, has always been a core issue of interest to gardening enthusiasts.
Complete Process of Parthenocissus tricuspidata Seed Propagation
Fruit Harvesting and Processing
From September to October each year, when the purple-blue berries mature, they need to be harvested in a timely manner. The fruit needs to be rubbed and washed to remove pectin, soaked in a 0.1% potassium permanganate solution for 15 minutes to sterilize, and then dried in the shade and stored in a 5℃ sand storage environment. Experimental data shows that the germination rate of seeds treated with stratification can increase by over 40%.
Scientific Germination Techniques
In the following March, mix the seeds with moist river sand at a ratio of 1:3 and place them in a constant temperature environment of 25℃ to induce germination. Turn the mixture twice a day to ensure aeration, and keep the wet gauze covering the seeds at 60% moisture content. Sowing can proceed when 30% of the seeds have whitened, and controlling temperature and humidity at this stage can shorten the seedling emergence period by 5-7 days.
Refined Sowing Management
Select a matrix mixed with peat soil and perlite at a ratio of 3:1, and control the sowing depth to 0.5cm. Maintain a ground temperature of 22-25℃ in the seedbed and use spray irrigation to prevent compaction. After seedlings emerge, gradually increase the light intensity, and apply a diluted balanced liquid fertilizer 2000 times when the true leaves unfold.
Key Techniques for Transplanting
When the seedlings grow to 15cm with 4 true leaves, choose a cloudy day for transplanting. Maintain a planting distance of 30cm and set up temporary trellises to guide growth. After transplanting, water thoroughly to settle the roots, cover with shade nets for 3 days to slow down the seedlings, and the survival rate can reach over 95%.
Seed Market Trend Analysis
Currently, the domestic seed prices show regional differences, with common varieties priced at 60-80 yuan per jin, and improved varieties reaching 120 yuan. Major producing areas such as Shandong and Jiangsu have prices 15-20% lower due to scaled production. It is recommended to choose seeds with a purity of ≥98% and a germination rate of ≥85% for quality seed sources.
Through scientific seed propagation techniques, it is possible to obtain stable-traits plants and significantly reduce the cost of green projects. Mastering the systematic methods from seed collection to seedling formation will add more ecological value to the urban space with this green curtain.
