“…Justifying the greater number of leaves up to 0.9 mM of SA in the conductivity of 1.1 dS m -1 and the more marked reduction in the higher concentration of acid due to the increase in saline levels. Raghami et al (2016) also found a beneficial effect on the number of leaves of eggplant seedlings using SA under salt stress.…”

“…There was a significant interaction for all variables analyzed, except the stem diameter, demonstrating that both factors, electrical conductivity of irrigation water (ECw) and application of SA interfere simultaneously in the growth of eggplant seedlings. Therefore, salicylic acid acts in the morphophysiological regulation of eggplant under salt stress conditions (Raghami et al, 2016).…”

Under salt stress conditions, plant growth is reduced due to osmotic, nutritional and oxidative imbalance. However, salicylic acid acts in the mitigation of this abiotic stress by promoting an increase in growth, photosynthesis, nitrogen metabolism, synthesis of osmoregulators and antioxidant enzymes. In this context, the objective was to evaluate the effect of salicylic acid doses on the growth and physiological changes of eggplant seedlings under salt stress. The experiment was conducted in a greenhouse, where the treatments were distributed in randomized blocks using a central composite matrix Box with five levels of electrical conductivity of irrigation water (CEw) (0.50; 1.08; 2.50; 3.92 and 4.50 dS m-1), associated with five doses of salicylic acid (SA) (0.00; 0.22; 0.75; 1.28 and 1.50 mM), with four repetitions and each plot composed of three plants. At 40 days after sowing, plant height, stem diameter, number of leaves, leaf area, electrolyte leakage, relative water content, and total dry mass were determined. ECw and SA application influenced the growth and physiological changes of eggplant seedlings. Increasing the ECw reduced growth in the absence of SA. Membrane damage with the use of SA remained stable up to 3.9 dS m-1 of ECw. The relative water content independent of the CEw increased with 1.0 mM of SA. The use of SA at the concentration of 1.0 mM mitigated the deleterious effect of salinity on seedling growth up to 2.50 dS m-1 of ECw.

“…Combined with the grafting technique, the adoption of a soilless cultivation system represents a sustainable approach due to the significant reduction in arable land, urbanization, water scarcity, and climate changes [23]. Soilless cultivation presents several advantages to eggplant greenhouse cultivation, including the notably enhanced regulation of nutrients within the solution medium, thus improving plant nutrient uptake [24]. As it is widely recognized, beyond the influence of the solution medium, the air temperature and substrate conditions also play crucial roles in a soilless eggplant cultivation system [25].…”

Grafting techniques represent an efficient tool to enhance plant growth and development. The study aims to explore the effects of different grafting combinations on the growth of eggplants under diverse greenhouse conditions. Eggplant cultivar Black bell (Bb) was employed as scion, while the hybrid F1 Beaufort (Be) and Solanum torvum (To) were utilized as rootstock. The hypothesis behind this study pertains to grafting incompatibility with Beaufort F1. It postulates that this incompatibility can be mitigated by manipulating soil and greenhouse temperatures. The experimental factors encompassed plant combinations (Bb, Be/Bb and To/Bb), as well greenhouse and substrate temperature (both cold or heated). The Be/Bb combination showed higher values of plant vegetative traits, but it exhibited low grafting compatibility. Additionally, physiological analysis confirmed the presence of excessive growth and vegetative disorder within the Be/Bb combination. Examination of the xylem vessels revealed notable differences between the grafting combination involving Bb and the rootstock F1 hybrid Be/Bb, compared to the one with To/Bb and the non-grafted Bb. Specifically, the area, diameter and number of xylem vessels were approximatively 45% higher in Be/Bb than in To/Bb and the non-grafted Bb. Furthermore, a robust linear correlation was observed between plant height with morphometric and physiological traits, except fruits sets. This study lays the basis for a novel protocol for agriculture, addressing the excessive vegetative growth in rootstocks regulating air and substrate temperatures.
