THE PRODUCTIVITY OF PHOTOSYNTHESIS AT THE SHOOTING-BUDONIZATION PERIOD FOR PEA SAMPLES AND SEMI-LEAFLESS SAMPLES

A study was made of the productivity of photosynthesis in peas of leafy and semi-leafless samples of the period shoots - budding under the conditions of the Krasnoyarsk forest-steppe. The following tasks were set: to analyze the elements that affect the intensity of photosynthesis during the period of germination - budding, and to evaluate the net productivity of photosynthesis in pea samples of different morphotypes. It was found that in the seedling phase, the indicators of the area of stipules and the collection of air-dry matter of semi-leafless samples can compete with leaf samples, even taking into account the summed area of their leaves and stipules. In the budding phase, the summed area of leaves and stipules of leaf samples exceeds those of semi-leafless samples. NPP and the maximum increase in dry matter for the accounting period shoots - budding was detected in a sample with a modified mustachioed type of leaf - Zh-55, with a minimum increase in the leaf surface.
