What are the environmental factors required during seed development?

Several environmental factors, such as temperature, water availability, soil pH, etc., influence seed germination and the optimum conditions necessary for this process to take place vary considerably depending on the species.

What environmental factors are required for seed germination?

Environmental factors such as temperature, light, pH, and soil moisture are known to affect seed germination (Chachalis and Reddy 2000; Taylorson 1987). Burial depth of seed also affects seed germination and seedling emer- gence. Weed seedlings may emerge from the soil surface to 15 cm deep (Bello et al.

What factors should be considered for the seeds to grow?

Major Factors Necessary for Seed Germination in Plants (Internal and External Factors)

  • Water: Germination cannot occur unless and until the seed is provided with an external supply of water. …
  • Oxygen: …
  • Temperature: …
  • Light: …
  • Other factors: …
  • Vitality: …
  • Longevity or viability: …
  • Dormancy:

Which is the most important factor for successful seed germination?

Moisture. Of all the factors that determine seed germination, water is the first and most important. Without water it cannot happen and a seed will stay dormant. But too much water and a seed will rot.

What are the factors affecting seed quality?

Seed quality depends upon the physical conditions that the mother plant is exposed to during growth stages, as well as harvesting, processing, storage and planting. Temperature, nutrients and other environmental factors also affect seed development and influence seed quality.

What are the factors affecting seed viability?

Seed longevity, vigor and viability depend on genetic and physiological factors as well as storage conditions. The most important factors that influence storage are temperature, moisture, seed characteristics, micro-organism geographical location and storage structure.

What factors contribute to the quality of a seed list and describe each of the factors that determine seed quality?

Trueness to variety; the presence of inert matter, seed of other crops, or weed seed; germination percentage; vigor; appearance; and freedom from disease are important aspects of seed quality. High-quality seed lots should meet minimum standards for each of these characteristics.

What are the effect of planting quality seeds?

Sowing good quality seeds leads to lower seed rate, better emergence (>70%), more uniformity, less replanting, and vigorous early growth which helps to increase resistance to insects and diseases, and decrease weeds. As a result, yield can increase by 5−20%.

How do you maintain quality of seeds?

After harvest, clean seed and select full and uniform seed. Dry seed to 12−14% moisture content. Store the seed in sealed airtight containers until ready for planting (seed is good for up to one year if stored properly). Seed in non-airtight containers absorbs moisture and loses viability over time.
