The effect of temperature and soil humidity on the growth at Pisum sativum L. subsp. sativumvar. Sativum
Keywords:
green beans, controlled conditions, abiotic factorsAbstract
Pots experiment with green peas was carried out in two climate chambers – KNER-2 and KNER-4, with air temperatures of 15 and 21оС. The illumination in both cameras is 18,000 lx. Up to the massive germination in all pors was maintained 70% soil moisture , after which the vessels were divided into three groups, in which three moisture regimes of the soil are maintained by daily watering in the weighing mode respectively – 50%, 70% and 90% soil moisture.
It was found that the air temperature of 15°C was insufficient for the normal sprouting of plants, with a combination of high soil moisture and 90% MOP. At the same time, these plants have the best vegetative development (height and mass of the stem and leaves). The best reproductive development (number and mass of peppers) are plants at 70% SM and 15°C and at 70% SM and 21°C. The highest dry mass and total sugars content are the 50% PWC, 21оС, and 70% SM, 21оС temperature.
