Pea (Pisum sativum L.) seedlings properties under influence of different temperatures

Seed quality determination has been conducted by various laboratory tests under optimal conditions therefore correlation with field results is questioned. To determine seed germination and seed properties (root length, hypocotyl length, length and mass of the seedling) in different agro ecological conditions an experiment with two cultivars of pees (Wonder van Amerika, Kelvedon wonder) in controlled conditions on higher and lower temperatures (10 °C and 20 °C) and with lightening schedule (12 hours light, 12 hours dark). Rolled paper towel method has been used where the paper was moisturized with plumbing water (pH7). There have been four repetitions with 50 seeds for every tested variation and measurement on 8th day and analyzed with 2- factorial variance analyzes with F and LSD test. Relations between tested parameters has been checked with correlation analyzes. Significant influence of tasted parameters (sort and temperature) on seedling properties has been determined as well as correlation between root length and hypocotyl length with mass and length of seedling. Average highest values have been determined for Wonder van Amerika and higher temperature. Due to age of seeds a significantly lower germination has been observed in comparison with declared ones (on package declaration).
