Effects of Functional Materials and Fertilizer Application on the Growth and Physiological Indicators of Pearl Apricot

Abstract

In order to study the effects of different amount of functional materials (FM) on pearl oil apricot, the study set up 0 g (control), 50 g (FM50), 200 g (FM200) and 300 g (FM300) of functional materials, and mixed with 2 kg of compound fertilizer as the base fertilizer. The growth and physiological indexes of pearl oil apricot and soil physicochemical properties were measured. Results showed that FM treatment significantly improved the pollen viability especially under FM300 treatment. FM200 and FM300 treatments significantly improved leaf carotenoids, anther size and anther quality of 100 seeds compared with the control. The anther width was significantly increased by 0.13 mm at FM300. However, physiological indexes such as filament length, anther length, pistil development type, hundred leaves length, hundred leaves width, hundred leaves thickness, hundred leaves weight and pollen fullness were not affected by FM. It can be seen that FM had a greater effect on growth and physiology indicators of pearl oil apricot, while the effect on soil physicochemical properties was smaller.
