“…Therefore, for blueberry cultivation, a reasonable amount of water and fertilizer is vital for the promotion of fruit growth and the production of stable and high yields. Current research on blueberries has focused mainly on agronomic traits [ 13 ], cultivation techniques [ 14 ], introduction and breeding [ 15 ], and processing [ 16 ]. Few studies have explored the impact of water and fertilizer coupling on blueberries [ 17 ].…”

Understanding the impact of irrigation and fertilizer on rabbiteye blueberry (Vaccinium virgatum) physiology is necessary for its precision planting. Here, we applied varied irrigation and fertilizer under completely randomized experimental design to see its impact on the physiological characteristics and bush growth of rabbiteye blueberries. A comprehensive evaluation of the membership function was used to establish the best water–fertilizer coupling regimes. Rabbiteye blueberry enhanced the net photosynthetic rate, stomatal conductance and transpiration rate of leaf and improved its photosynthetic capacity at maximum level of irrigation water and fertilizer application (F3W4). The high fertilizer–medium water treatment (F3W3) increased leaf-soluble protein contents. The medium fertilizer–medium water treatment (F2W3, F2W2) increased leaf- soluble sugar, superoxide dismutase, and chlorophyll contents; decreased the malondialdehyde content; and enhanced leaf resistance and metabolism. It also promoted the growth of flower buds and new shoots. Combined membership function and cluster analyses revealed that the optimal water and fertilizer conditions for promoting rabbiteye blueberry plant growth were the medium fertilizer–medium water [(NH4)2SO4:Ca(H2PO4)2:K2SO4 at 59:10:20 g plant-1; 2.5 L water plant-1], medium fertilizer–medium-high water [(NH4)2SO4:Ca(H2PO4)2:K2SO4 at 59:10:20 g plant-1; 3.75 L water plant-1], and high fertilizer–medium-high water [(NH4)2SO4:Ca(H2PO4)2:K2SO4 at 118:20:40 g plant-1; 3.75 L water plant-1] treatments. The findings of this study could be used in improving the precision and efficacy of rabbiteye blueberry planting in Guizhou, China. Such an approach can increase the productivity and profitability for local fruit farmers.

“…However, subsequent studies did not place it among the geographical races of G. hirsutum [ 44 ]. There is a possibility that G. purpurascens has been naturally occurring in the South China Sea Islands for centuries without human intervention [ 45 ]. It is unknown where it came from, its evolutionary connection, when it was brought to these places, or how it was brought there.…”

Elevated salinity significantly threatens cotton growth, particularly during the germination and seedling stages. The utilization of primitive species of Gossypium hirsutum, specifically Gossypium purpurascens, has the potential to facilitate the restoration of genetic diversity that has been depleted due to selective breeding in modern cultivars. This investigation evaluated 45 G. purpurascens varieties and a salt-tolerant cotton variety based on 34 morphological, physiological, and biochemical indicators and comprehensive salt tolerance index values. This study effectively identified a total of 19 salt-tolerant and two salt-resistant varieties. Furthermore, transcriptome sequencing of a salt-tolerant genotype (Nayanmian-2; NY2) and a salt-sensitive genotype (Sanshagaopao-2; GP2) revealed 2776, 6680, 4660, and 4174 differentially expressed genes (DEGs) under 0.5, 3, 12, and 24 h of salt stress. Gene ontology enrichment analysis indicated that the DEGs exhibited significant enrichment in biological processes like metabolic (GO:0008152) and cellular (GO:0009987) processes. MAPK signaling, plant-pathogen interaction, starch and sucrose metabolism, plant hormone signaling, photosynthesis, and fatty acid metabolism were identified as key KEGG pathways involved in salinity stress. Among the DEGs, including NAC, MYB, WRKY, ERF, bHLH, and bZIP, transcription factors, receptor-like kinases, and carbohydrate-active enzymes were crucial in salinity tolerance. Weighted gene co-expression network analysis (WGCNA) unveiled associations of salt-tolerant genotypes with flavonoid metabolism, carbon metabolism, and MAPK signaling pathways. Identifying nine hub genes (MYB4, MYB105, MYB36, bZIP19, bZIP43, FRS2 SMARCAL1, BBX21, F-box) across various intervals offered insights into the transcriptional regulation mechanism of salt tolerance in G. purpurascens. This study lays the groundwork for understanding the important pathways and gene networks in response to salt stress, thereby providing a foundation for enhancing salt tolerance in upland cotton.

No Brasil, as cultivares de mirtileiro, exploradas economicamente, foram introduzidas de outros países e, sendo assim, selecionadas em outras condições edafoclimáticas, podendo apresentar limitações para seu cultivo. Visando à obtenção de plantas superiores mais adaptadas para as condições brasileiras, realizou-se a seleção em três populações de mirtileiro de polinização aberta com o objetivo de obter progênies superiores. O material vegetal utilizado constituiu-se de 3.554 plantas, provenientes de sementes das cultivares Bluegem (1.212 plantas), Bluebelle (1.439 plantas) e Powderblue (903 plantas). O experimento foi conduzido em área previamente adubada, conforme análise de solo, em espaçamento de 30 x 30 cm, com sistema de irrigação por aspersäo. A seleção nas plantas das três populações foi realizada em três etapas (2007/2008, 2008/2009 e 2010/2011). No primeiro ciclo, realizou-se a seleção negativa, eliminando-se as plantas indesejáveis; no segundo, foi realizada a seleção positiva, quando foram selecionadas 20 plantas de cada uma das populações. Como critério de seleção, nos dois primeiros ciclos, foram usados os seguintes caracteres: vigor da planta, produção, estado fitossanitário, início de produção, presença de pruína na epiderme, tamanho e sabor do fruto. Ao final do segundo ciclo, as 20 plantas pré-selecionadas de cada população foram avaliadas, por um período de dois anos (2009/2010 e 2010/2011), registrando-se a produtividade das plantas e as variáveis químicas dos frutos. Com base nos resultados obtidos, pode-se concluir que 10 genótipos (BG5, BG2, BG3, BG6, PW3, PW5, PW1, BB10, BB5 e BB2) têm potencial para dar-se continuidade ao processo de seleção, pois apresentam bom desenvolvimento vegetativo, frutos de boa qualidade e de tamanho adequado ao mercado consumidor.
