Effect of Temperature, Media and Light on Germination of Prinsepia utilis Royle Seeds

Abstract

Effect of temperature and media was studied on seed germination of Prinsepia utilis Royle (bhekal). Germination tests were conducted at four different temperatures viz. 5±1 o C, 15±1 o C, 25±1 o C and ambient room temperature with three germination media viz. top of germination paper (TP), between of paper (BP) and quartz sterilized sand at 90±5% relative humidity in a seed germinator for 21 days. Media and Temperature significantly affected seed traits. Seeds germinated well over wide range of temperature 15±1 o C, to ambient room. Significantly, higher germination percentage, germination value (GV) and minimum mean germination time (MGT) were obtained at 25±1 o C. lower than 25±1 o C and higher temperature (ambient room temperature) had adverse effect on germination of bhekal seeds. Among media, between paper (BP) was found the best in which maximum germination percentage, minimum MGT and maximum GV was recorded. Sand media was found inferior as compared to between and top of paper. Seed germination was unaffected with light.

Assessing the Climate Adaptive Potential of Imported Chili in Comparison with Local Cultivars through Germination Performance Analysis

“…The discrepancy could be explained by genetic changes that affect chlorophyll synthesis or by unfavorable environmental conditions that affect the cultivar [5]. The nding highlights the genetic diversity and exibility of chili cultivars, since several have proven to have better development traits in particular environmental circumstances [29]. The cultivar's early robust growth can be ascribed to innate genetic characteristics, such as effective nutrient uptake, improved establishment of roots, and resistance to early-stage growth-related stresses [30].…”
