“…Based on this approach, the MF was used to comprehensively evaluate the soil pH tolerance of the different blueberry cultivars. The results obtained using the above analysis method are reliable and have been applied to the comprehensive evaluation of resistance in Cucumis melo L. (Weng et al, 2021), Vitis vinifera L. (Karimi & Salimi, 2021), Prunussalicina L. (Hamdani et al, 2021), Populus deltoides Marsh. (Chen et al, 2022), Quercus (Xiong et al, 2022), Populus simonii × Populus nigra (Liu et al, 2022) and other plants.…”

High soil pH is one of the main abiotic factors that negatively affects blueberry growth and cultivation. However, no comprehensive evaluation of the high soil pH tolerance of different blueberry cultivars has been conducted. Herein, 16 phenotypic and physiological indices of 15 blueberry cultivars were measured through pot experiments, and the high-pH soil tolerance coefficient (HSTC) was calculated based on these indices to comprehensively evaluate the high-soil-pH tolerance of plants. The results demonstrated that high soil pH stress inhibited blueberry 77.growth, and MDA, soluble sugar (SS), and soluble protein (SP) levels increased in leaves. Moreover, in all cultivars, CAT activity in the antioxidant system was enhanced, whereas SOD activity was reduced, and the relative expression levels of the antioxidant enzyme genes SOD and CAT showed similar changes. In addition, the leaf chlorophyll relative content (SPAD), net photosynthetic rate (Pn), transpiration rate (E), and stomatal conductance (Gs) decreased, while changes in the intercellular CO2 concentration (Ci) were noted in different cultivars. Finally, according to the comprehensive evaluation value D obtained from the combination of principal component analysis (PCA) and membership function (MF), the 15 blueberry cultivars can be divided into 4 categories: high soil pH-tolerant type [‘Briteblue’ (highest D value 0.815)], intermediate tolerance type (‘Zhaixuan 9’, ‘Zhaixuan 7’, ‘Emerald’, ‘Primadonna’, ‘Powderblue’ and ‘Chandler’), low high soil pH-tolerant type (‘Brightwell’, ‘Gardenblue’, ‘Plolific’ and ‘Sharpblue’) and high soil pH-sensitive type [‘Legacy’, ‘Bluegold’, ‘Baldwin’ and ‘Anna’ (lowest D value 0.166)]. Stepwise linear regression analysis revealed that plant height, SS, E, leaf length, Ci, SOD, and SPAD could be used to predict and evaluate the high soil pH tolerance of blueberry cultivars.

“…In wheat, 12 physiological and biochemical indicators, including stomatal conductance, proline and malondialdehyde, were found to be associated with drought resistance via the use of multivariate statistical methods. In plum [ 28 ], through cluster analysis and principal component analysis, multiple traits related to drought resistance were attributed to five indicators, leaf area, stomatal density, and stomatal area, to evaluate drought resistance. Similar methods have also been applied in plants such as melon [ 29 ], grape [ 30 ], and canna [ 31 ].…”

Background Focusing on key indicators of drought resistance is highly important for quickly mining candidate genes related to drought resistance in cotton. Results In the present study, drought resistance was identified in drought resistance-related RIL populations during the flowering and boll stages, and multiple traits were evaluated; these traits included three key indicators: plant height (PH), single boll weight (SBW) and transpiration rate (Tr). Based on these three key indicators, three groups of extreme mixing pools were constructed for BSA-seq. Based on the mapping interval of each trait, a total of 6.27 Mb QTL intervals were selected on chromosomes A13 (3.2 Mb), A10 (2.45 Mb) and A07 (0.62 Mb) as the focus of this study. Based on the annotation information and qRT‒PCR analysis, three key genes that may be involved in the drought stress response of cotton were screened: GhF6'H1, Gh3AT1 and GhPER55. qRT‒PCR analysis of parental and extreme germplasm materials revealed that the expression of these genes changed significantly under drought stress. Cotton VIGS experiments verified the important impact of key genes on cotton drought resistance. Conclusions This study focused on the key indicators of drought resistance, laying the foundation for the rapid mining of drought-resistant candidate genes in cotton and providing genetic resources for directed molecular breeding of drought resistance in cotton.

“…This fruit crop is the second most cultivated stone fruit in the world after peaches and nectarines, with total world production reaching 12.2 million tones cultivated on an area of 2.6 million hectares (Fadon et al, 2020). In Morocco, plum is one of the main crops, with a harvested area of more than 16,198 ha and an estimated annual production of about 143,457 tones/year (Hamdani et al, 2021). Climate change is a widely accepted reality and its effects on such crop are being felt.…”

The date of endodormancy release and chill requirements of twenty-eight plum cultivars (Prunus domestica L. and Prunus salicina Lindl) growing in a collection at the experimental station of the National Institute of Agricultural Research of Meknes (Morocco) were determined according to three models namely the Chilling Hours model (in Chilling Hours, CH), the Utah model (in Chill Units, CU) and the Dynamic model (in Chill Portions, CP). In this regard, the forcing tests were conducted out on floral buds of all plum cultivars in order to follow the weight of buds in field and under controlled climate conditions. The heat requirements calculation was based on counting the Growing Hours Degree between the endodormancy release date determined by forcing tests and the flowering dates observed in field for each cultivar. Significant differences were revealed in chill and heat requirements between the plum cultivars studied, ranging from 336 to 522 CH, 645 to 1,046 CU, 37.5 to 55.93 CP and 6,618 to 9,673 GDH according to Chilling Hours, Utah, Dynamic and GDH models, respectively. In addition, the results showed great variability between cultivars according to their dormancy levels, ranging from low chill and heat cultivars (INRA-PR38, INRA-PR40 and Santa Rosa) to highest ones (Stanley, Prune d’Ente, Monglobe and Fortune), which generated differences in the dates of endodormancy release and flowering process. Correlations between chill requirements, heat requirements and flowering dates have been established since cultivars with low chill requirements (also low heat requirements) have earlier endodormancy release and flowering dates in comparison to those showed high chill requirements. The results obtained in this investigation constitute a basis to improve knowledge of the plum species cultivated under Moroccan climate conditions and make it possible to determine the most appropriate cultivation areas for these cultivars, given the current and future climate change.
