Plum (Prunus domestica L.) and its wild relatives are found at different locations in Pakistan, existing in naturalized form, which have not been characterized yet. In the present work, genetic diversity in morpho-physiological characteristics of sixteen plum genotypes growing in the area of Rawalakot, district Poonch, Azad Jammu and Kashmir, Pakistan were studied. Various parameters like tree size, number of branches per plant, leaf area, number of flowers per plant, blooming period, number and percentage of fruits set per plant, number and percentage of fruits matured per plant, fruit size and fruit weight were taken into count and variation observed in these characteristics was discussed. The results suggested that the plum genotypes differed in their morpho-physiological traits, and this ultimately provides important information on how to make the best use of these plum genotypes in future breeding programmes. The differences were probably due to their genetic make-up as well as prevailing climatic factors in the region.

The usage of artificial light is excessive and improper. Earth's night picture has changed significantly from space and studies have shown that over-exposure to artificial light in the night can influence animals, the environment and human beings. The purpose of this study was to monitor and measure skylights of Lahore City and temporary light pollution from 2012-2019. The Suite-Day/Night band of the Visible Image Radiometer was used for time changes analysis with GIS and Remote Sensing tools. Indicators were established as a table tool through zonal statistics, and a field survey was also undertaken to measure the Sky-Glow of Lahore with Sky Quality Meter-L. The results suggest that from 2012 to 2019, light pollution rose by 23.43 percent. Results suggest that around 53.99% of Lahore suffered from light pollution. The number of lights in Lahore has increased by 161.82 percent between 2012 and 2019. In the study period, the mean night light and the standard night light deviation were 127.87 and 98.22 percent, respectively. Lahore's night sky was heavily polluted by light. Lahore's average skylight is 17.15 meters above sea level, which means low quality skies at night. This research aims to provide people an insight into light pollution and the causes of local light pollution. Furthermore, this study aims to enhance public attention to light pollution mitigation attempts by governments and politicians.
