Seed dormancy testing and germination frequency determination of Psoralea corylifolia L., an endangered medicinal plant

Abstract

Seed dormancy is one of important factor which prevent the cultivation of medicinally important plant Psoralea corylifolia. Mechanical dormancy is present in the seed due to hard seed coat. P. corylifolia is a slow growing species due to low germination percentage (5-7%). Long gestation period and delicate field handling discourages the commercial cultivation of the plant so different treatments were used to break dormancy in seeds. Out of five different methods used 98% concentrated H 2 SO 4 for about one hour was found to be best method for seed dormancy breakage. Statistical analysis of data was performed by one way ANOVA using Sigma State Software version 4.

The potential impact data of Tylosin and Enrofloxacin veterinary antibiotics on germination and accumulation in barley seed as a forage crop and good dietary sources using LC/MS-MS

“…Seeds were considered germination with the emergence of radical. The germination percentage was determined by counting the number of seeds germinated during the experiment period (six days) over the total number of seeds according to Equation (1), [1].$\text{Germination\%}=\frac{\text{Number}\text{of}\text{germinated}\text{seeds}}{\text{Total}\text{number}\text{of}\text{seeds}}\times 100$…”

“…[3]. However, several reports have indicated that PC is regarded as an endangered medicinal plant in India, so the research of this plant has attracted much attentions [4,5]. Modern pharmacological studies have shown that the dried fruit of the plant has anti-bacterial [6], anti-diabetic [7], anti-depressant [8], anti-oxidative [9], anti-fungal [10], anti-inflammatory [11], and many other effective activities.…”
