The aim of this experimental study was to investigate the effective infertility factors of physoaline compounds on the adult reproductive system of Balb/C adult female.

The above experiment was performed by preparing the aqueous extract of the plant and selecting three doses of 7.5g/kg,9g/kg and 15g/kg;Simultaneously with the experimental groups,the distilled water sham group was injected and the control group was kept intact.Vaginal stromal smear cycles were prepared to examine different stages.One hour after the last injection,the mice were given blood samples and then killed by chloroform and their uterus and ovaries were prepared for histological studies.

Statistical studies have shown that injecting 7.5g/kg of extract reduces estrogen and restores 33% of fertility in mice. Also, at a dose of 9 g/kg, the mice were initially infertile, but one month after the last injection, 16.5% of the mice showed a return to fertility and a significant increase in progesterone.

According to the results, it is probably because physalines have a pseudo-steroidal structure. The receptor is occupied by physaline and can cause abnormalities in the growth and development of oocytes, uterine tissue cells and ovaries, and infertility.

In order to study the effects of biofertilizers of nitroxin (0, 2, 4 L.h-1) and biosulphur (0, 2, 4 kg.h-1) Containing “plant growth promotor Bacteria” on quantity and quality of medicinal plant of winter cherry (Physalis alkekengi L.) an experiment in a factorial experiment based on randomized complete block design with nine treatments (Nitroxin 2 and 4 L.h-1, Biosulphur 2 and 4 kg.h-1, Nitroxin 2 L.h-1 + Biosulphur 2 kg.h-1, Nitroxin 2 L.h-1 + Biosulphur 4 kg.h-1, Nitroxin 4 L.h-1 + Biosulphur 2 kg.h-1, , Nitroxin 4 L.h-1 + Biosulphur 4 kg.h-1 and No Biofertilizer) and three replications was conducted in agricultural faculty of Zanjan University in 2016. Results of this experiment showed that biofertilizers of Nitroxin and biosulfur had significant effect on growth indices, yield and quality of winter cherry but weight of Calyx not affected by experimental treatments. The maximum Plant height  (53 cm), stem diameter (6.1 mm), internod distance (7.33 mm), leaf area (422.3 cm2), number of branches (58), Aerial part fresh weight (371.3 g), Aerial part dry weight (78 g) were obtained in integrated treatment of four liters nitroxin with four kilograms of biosulfur. The maximum fruit weight (1.96 g), fruit diameter (1.96 mm), total yield  (6.82 t.h-1), Chlorophyll a (4.01 mg.g-1 leaf fresh weight), leaf nitrogen content (3.02 percent), leaf sulfur content (0.20 percent) were obtained in integrated treatment of four liters nitroxin with four kilograms of biosulfur. Also, the most total phenol (14.07 mg/g fruit DW), carotenoids (12.16 mg/g fruit FW), anthocyanins (17.7 mg mg/g fruit DW), and physaline (1.56 percent) obtained in treatment of four liters nitroxin per hectare. Most of the chlorophyll b (2.76 mg/g leaf fresh weight) in integrated treatment of two kilograms per hectare of biosulfur with four liters per hectare of nitroxin. Overall, based on results it seem that biofertilizers of Nitroxin and biosulfur application can increase the economic performance, quality and quantity characteristics of winter cherry compared to control.
