In the study in which fresh seedlings were used, planted on the rows in a triangular form at intervals of 20×20 cm in double rows. Irrigation applications were carried out by drip irrigation method and the amount of irrigation water in the control treatment (I100) was calculated using measurements taken from an A-Class evaporation pan. Eight irrigation treatments including four traditional irrigation (I100, I80, I60, I40) and four fixed-partial root drying (F-PRD100, F-PRD80, F-PRD60, F-PRD40) were examined within the scope of the study. In traditional irrigation (I100, I80, I60, I40) applications, both sides of the plant root zone were irrigated. However, during the entire growing season in the fixed-partial root drying (F-PRD100, F-PRD80, F-PRD60, F-PRD40) technique, one-half of the plant root zone was kept wet, and the other half was left relatively dry. The yield values were ranked as, from high to low, F-PRD100>I100>F-PRD80>I80>F-PRD60>I60>I40>F-PRD40. In irrigation treatments, the yield values obtained from I80 and F-PRD80 treatments were statistically similar (Duncan 5%) to the yield values of I100 and F-PRD100 treatments. However, it could be stated that the F-PRD80 is more advantageous. It was found that different amounts of irrigation water (100%, 80%, 60% and 40%) affects the yield and yield-related parameters obtained from the strawberry plants. In general, as the water deficit increased (in the I40 and F-PRD40 treatments), the level of negative impact also increased. As a result of the research, F-PRD80 was proposed for the cultivation of strawberries, particularly, in arid and semi-arid regions, depending on the availability of water.","PeriodicalId":19364,"journal":{"name":"Notulae Botanicae Horti Agrobotanici Cluj-napoca","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2023-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49580759","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The development of an asexual propagation protocol as a first step towards utilization of Greek C. sanguinea germplasm is presented herein for the first time. Plant material was collected from C. sanguinea‘s natural habitat during winter dormancy (hardwood cuttings) as well as during early vegetative growth (softwood cuttings). The propagation protocol was developed through preliminary trials for the successful propagation of the material sourced directly from the wild to establish enough starting material (ex situ adapted mother plants); consecutively, cutting propagation experiments over a two-year period coupled with early plant growth and survival assessment were conducted. The results showed that the use of external indole-3-butyric acid (IBA) rooting hormone application between 2,000 and 4,000 ppm delivered very high rooting rates (80-100%) via the use of primary softwood, leafy cuttings with minimum amount of lignification under mist. The proposed protocol is considered fast, reliable, easy to implement and economically viable. The study provides first time data on domestication and propagation of Greek C. sanguinea germplasm and at the same time paves the way for further research on the sustainable utilization of this species.","PeriodicalId":19364,"journal":{"name":"Notulae Botanicae Horti Agrobotanici Cluj-napoca","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2023-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48190851","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cold stress has significantly curtailed soybean growth and yield in large areas and caused a high risk to global food security. The main objective of soybean breeders is to improve soybean resistance to cold stress. Conventional breeding approaches have made significant progress in developing cold tolerance in soybean; however, the high cost and complex genetic mechanism of cold tolerance hindered the large scale of these techniques. Molecular tools like quantitative trait loci (QTL), genome-wide association studies (GWAS), transcription factors (TFs), genetic engineering, and transcriptome have been used to identify cold tolerant genes/QTL and to develop soybean cultivars tolerant to cold stress. Clustered, regularly interspaced short palindromic repeats (CRISPR/Cas9) is used to increase the abiotic stress tolerance in soybean; however, its use to edit the cold tolerance genes in soybean is limited. Mapping of QTL has accelerated the master-assisted selection (MAS) in soybean. This review presents a detailed overview of molecular techniques and their use in developing cold-tolerant soybean cultivars. Using CRISPR/Cas9 would increase the speed of molecular breeding for cold tolerance in soybean. This information will assist soybean researchers in uncovering the basis of cold stress tolerance in soybean and adopting the most suitable way to breed the cold tolerant cultivars which can thrive under the extreme pressure of cold stress.","PeriodicalId":19364,"journal":{"name":"Notulae Botanicae Horti Agrobotanici Cluj-napoca","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2023-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45960050","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our results show that varying light quality influence morphological traits and flower appearance. Both blue and red light improved the development of first and second internodes and induced larger leaves and petiole lengths, whereas 10:4 mixture caused shorter plant heights and decreased internode and petiole lengths. Although 10:8 mixture treatment reduced chlorophyll content, this spectral regime increased leaf number and influenced flower sex development, inducing more female flowers and more fruits. Light quality manipulation thus beneficially influences the growth and flower sex proportion in squash plants.

Identifying the flower induction-related genes and analyzing their regulation mechanism is the key to solve this problem. The APETALA2/ethylene responsive factor (AP2/ERF) superfamily members are transcription factors (TFs) that regulate diverse developmental processes, including flowering time, and stress responses in plants. However, there is still no research about AP2/ERF involved in the regulation of longan flower induction. In the present study, a AP2/ERF TF member DlERF23 was cloned from longan (Dimocarpus longan). It has a typical AP2 domain with the coding sequence (CDS) of DlERF23 is 552 bp in length and encodes 184 amino acids. The molecular weight of DlERF23 protein was 20.41 kda and the theoretical isoelectric point (PI) was 7.69. The amino acid sequence of DlERF23 protein had the highest similarity with CsERF23 (XP_006478313.1) of Citrus sinensis and CcERF23 (XP_006441807.2) of Citrus clementina. The results of qRT-PCR showed that the relative expression level of DlERF23 gene in pericarp was higher, followed by stem, leave, flower and flower bud. Meanwhile, DlERF23 gene significant down-regulated in the early stage of flower induction in ‘Sijimi’ (SJ) longan and up-regulated in the late stage of flower induction in ‘Shixia’ (SX). The results of transient expression of Arabidopsis protoplasts showed that the fluorescence signal was mainly concentrated in the nucleus. Moreover, overexpression of DlERF23 in Arabidopsis promoted early flowering. These results provide useful information for revealing the biological roles of DlERF23 in longan and increase our understanding of the AP2/ERF superfamily members in fruit trees.","PeriodicalId":19364,"journal":{"name":"Notulae Botanicae Horti Agrobotanici Cluj-napoca","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2023-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42627313","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
