Growth parameters for pine trees including; tree height, crown height, diameter at breast height, stand density level, location within the stand, health condition, in addition to the observed number of PPM nests per tree were recorded. Pearson correlation coefficient analysis and variance analysis were applied to assess the relationship between obtained variables, and evaluate growth conditions for both stands. Results revealed relatively better growth conditions at Al-Mansurra site compared to Cyrene site. Moreover, PPM nests occurrence was positively correlated with trees growing isolated or on the stand edge (r = 0.54, P value <.001), and negatively correlated with tree height (r = - 0.4, P value <.001) emphasizing more dispersal rate among young pine trees. Crown height, dbh, and tree’s health condition showed no significant effect on PPM spread in the area. In-depth investigations of the population dynamics of PPM are highly recommended to provide insights into their spatial distribution in the region.

The 1stcluster contained three populations that were included white-flowered, dotted white-flowered and violet-flowered accession, then the 1st cluster was divided into two sub-clusters by the critical distance value of 5%, the first sub-cluster contained two populations (white-flowered, dotted white-flowered accession). While, the second sub-cluster contained one population (violet-flowered accession). The 2nd cluster contained two populations which were purple-flowered and mosaic-flowered accessions.

Irrigation levels were determined as percentages (WI 100% as readily available water to the crop (RAW)), and for the rest of the treatments (WII 75%, WIII 50%), as they were applied separately to all four stages of crop growth i.e., vegetative (SI), tuber initiation (SII), tuber bulking SIII, and tuber maturation (SIV). The design of complete random sectors was adopted to perform the experiments. The results revealed that all the studied parameters: plant height (cm), vegetation plant weight (g), number of tubers per plant, tuber weight (g), tuber yield (ton/ha), and crop water productivity (kg/m3) varied among irrigation water levels at different stages of growth. It was found that the two stages, SII and SIII in potato crops, were more sensitive to deficit irrigation compared to other stages. According to the obtained results, in the case of water abundance conditions, the treatment WII SI can be applied to obtain the highest water crop productivity. In conditions of water scarcity, it becomes necessary to apply the treatment WIII SIII to obtain the highest crop water productivity.","PeriodicalId":276609,"journal":{"name":"Al-Mukhtar Journal of Sciences","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117159351","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The obtained results showed that the use of calcium chloride sprayed on the fruits better preserved their quality compared to the non-sprayed ones.
