Detailed Guide to Paris polyphylla Seed Germination Methods and Flowering Time
Paris polyphylla is very common in daily life; its leaves are single, and a long stem grows from the center, which is its flower. Nowadays, people in many places cultivate Paris polyphylla specifically, but when planting it, regarding its germination methods and flowering time, many people are not clear about them. Let's take a look below!
How to Germinate Paris polyphylla Seeds
1. When germinating Paris polyphylla seeds, it can be done according to a certain ratio. Generally, 2500 seeds per sq m are broadcast on a greenhouse seedbed, with the seedbed 1.2 m wide, 20 cm high, and furrows 30 cm wide. After sowing, cover the seeds with a 1:1 mixture of humus soil and plant ash, with a soil cover thickness of about 1.5 cm, then cover the bed surface with a layer of pine needles or chopped grass, with a thickness that does not expose the soil, water thoroughly, and keep moist. With good management after sowing, seedlings can begin to emerge in May to June, and the emergence rate can reach over 60%, so it is still quite high.
2. Before sowing, the seedbed needs some weeding and disinfection work. The seedbed soil should be loose and fertile, with a bed soil layer thickness of 20-30 cm. At the same time, apply carbendazim wettable powder at 1% of the seed weight and mix well, place in a germination box, put indoors, and maintain the germination temperature at 18-22°C. Check once every 15 days, keeping the soil (or sand) moisture at 30-40% (a handful of sand held tightly in the hand can form a clump, and it is suitable if it disperses when released). After the Paris polyphylla seeds have grown some new roots, they can be sown.
Which Month Does Paris polyphylla Bloom
The flowering time of Paris polyphylla is generally from June to July each year. The pedicel emerges from the top of the stem, bearing one terminal flower; the flower is bisexual, with sepals lanceolate or long ovate, green, 3.5-150px long; the tepals are linear and slightly lanceolate, yellow, about 1/2 the length of the sepals to nearly equal in length, more than 2-6mm wide above the middle; stamens 8-10, anthers l-37.5px long; filaments shorter than the anthers, with the protruding part of the connective 1-2mm. The flowers of Paris polyphylla are still very beautiful.
Growth Habits of Paris polyphylla
1. Temperature: Paris polyphylla is still very resistant to low-temperature environments, so its temperature requirements are not very high. From late February to early March, at a temperature of 5°C, and even at a minimum temperature of 2°C, it can still sprout and grow. At 1-2°C, the bud tips do not suffer freeze damage. Generally, the suitable temperature for seed germination, root growth and development, and terminal bud germination is 18°C-20°C, for emergence is 20°C, for aboveground plant growth is 16°C-20°C, and for underground rhizome growth is 14°C-18°C. More attention should also be paid to the choice of temperature.
2. Light: Paris polyphylla prefers shade and cannot accept too strong sunlight, so when planting, shading work is also very important. Strong light will cause the leaves to wither. Generally, the seed germination and seedling stages require better shading, and one or two years before maturity, the shading can be appropriately reduced somewhat, which is beneficial to its growth.
The flowering time of Paris polyphylla is generally in summer each year. When germinating seeds, first do the land preparation work well, then sow the seeds in an appropriate amount, and after germination, plant them at the right time. Paris polyphylla likes to grow in warm places and is not tolerant of strong light, so shading treatment needs to be done well.
