The effects of soil drought stress on growth characteristics, root system, and tissue anatomy of Pinus sylvestris var. mongolica.

ABSTRACT: The main purpose of this study was to study the changes in growth, root system, and tissue anatomical structure of Pinus sylvestris var. mongolica under soil drought conditions. In this study, the growth indexes and photosynthesis of P. sylvestris var. mongolica seedlings under soil drought stress were studied by pot cultivation. Continuous pot water control experiment of the indoor culture of P. sylvestris var. mongolica was carried out, ensuring that the soil water content of each treatment reached 80%, 40%, and 20% of the field moisture capacity as control, moderate drought and severe drought, respectively. The submicroscopic structures of the needles and roots were observed using a scanning electron microscope and a transmission electron micros
