“…These reductions may be due to the excessive deposition of Na + and Clions in the seed tissues that compromise germinative metabolism, affecting the mobilization of mineral and organic reserves beyond the return of breathing (Shahid et al, 2011). These results were consistent with those of Campos et al (2007) and Chakma et al (2019) in tomato, Larré et al (2011) in rice, and Azhar et al (2017) in barley, that they said salinity affect the germination of seeds beyond the seedling growth, due to difficulty in the absorption of water. However, the results of the last authors differed from those of this study regarding the attenuation of saline stress by EBL on germination since the soaking of rice seeds for two hours at 0.01; 0.1 and 1 μM EBL mitigated the negative effect of salinity on the percentage of germination and germination speed index, especially in the sensitive cultivar, while barley seeds germinated in saline solutions with 0.1; 0.25 and 0.5 mg L -1 of EBL improved the germination percentage, depending on the concentration and intensity of salt stress (Azhar et al, 2017).…”

“…Under salinity conditions, it was observed in IPA 6 tomato cultivar that water salinity by 5.0 dS m -1 did not affect the germination rate but reduced the speed of emergence with the increase in saline stress (Campos et al, 2007). In another study also with tomato, the percent seed germination decreased with increasing salt concentration, 68.2% (0 mM) to 5.9% (150 mM) in different varieties (Chakma et al, 2019). In pepper, the seed germination also gradually decreased as the NaCl concentration increased (Demir and Mavi, 2008).…”

Salinity is one of the environmental stresses that most affects plants' vital processes, especially germination. Brassinosteroids, including 24-epibrassinolide (EBL), have multiple actions in essential processes in plants. Thus, this research's objective was to evaluate the effects of EBL on tomato seeds' physiological conditioning on germination, growth, and production of dry seedling mass under salinity conditions. The experiment was carried out in a 2x5 factorial scheme, as follows: two concentrations of EBL (0 and 10-6 M) and five levels of salinity (0.5 control; 1.5; 3.0; 4.5 and 6.0 dS m-1), consisting of ten treatments, with four replications of 50 seeds. In isolation, the salt stress reduced the percentage of germination and germination speed index from four to 14 days, besides all the plants' growth traits. In turn, the EBL increased the percentage of germination, germination speed index, seedling length, and radicle dry matter. The application of 10-6 M of EBL in seed immersion no effect on the seed germination of IPA 6 tomato cultivar under salt stress but increases the root length and the dry matter of the seedlings.

“…This is due to the effects of high osmotic potential and specific ion toxicity (accumulation of Na + and Clions) (Khan & Weber, 2008). The present findings are in line with previous reports on the mean germination rate (Cunhua et al, 2012;Sardoei & Mohammadi, 2014), speed of germination (Nasrin & Mannan 2019), germination energy (Nasrin & Mannan, 2019) and mean germination time (Chakma & Hossain, 2019) of the tomato seeds. Salinity notably affects germination in many species but also increases the time required to complete germination (Nawaz et al, 2011).…”

“…This indicates that the Sirinka variety is more sensitive to salinity than the other varieties. The combined effect of variety and salinity had a significant effect on the mean germination rate (Cunhua et al, 2012;Sardoei and Mohammadi, 2014;Moles et al, 2019), mean germination time (Sholi 2012;Chakma & Hossain, 2019), speed of germination (Nasrin & Mannan, 2019;Moles et al, 2019) and germination energy (Nasrin & Mannan, 2019), which supports the findings of this study.…”

Salinity adversely affects 20-30% of the irrigated area in the world. Tomato is sensitive to salinity. It is one of the most severe abiotic factors of many agricultural crops and it becoming the main problem in Ethiopia. This study was conducted to evaluate the effects of different salinity levels on the seed germination parameters of tomato varieties. It was laid out in a completely randomized design with three replicates. The treatment included four tomato varieties (Sirinka, Weyno, ARP D2, and Roma VF) and five salinity levels (1 dS m-1, 2 dS m-1, 3 dS m-1, 4 dS m-1, and control). Fifty seeds were placed in a Petri dish over a moistened germination paper for germination and seedlings and allowed to grow for 14 days. The germination rate, speed and energy of tomato seeds were significantly (p < 0.001) affected by the combined effect of variety and salinity. The shortest mean germination time, the highest mean germination rate, and the highest speed of germination were recorded in the ARP D2 variety in the control treatment. The lowest first and last days of germination, and the uncertainty of germination were recorded from ARP D2. However, an increase in the days of germination and in the uncertainty of germination, and a decrease in the germination index and total germination percentage trends were observed with increasing salinity levels. The highest level of salinity (4 dS m-1) affected the germination of tomato varieties. Among the four tested tomato varieties, ARP D2 and Roma VF were tolerant to salinity.

“…This moderate tolerance of cape gooseberry is very similar to many tomato varieties (Chakma et al, 2019) and is important in the scenario of increased saline areas generated by anthropogenic effects or by factors related to climate change (Ngasoh et al, 2019).…”

In order to review the literature on the ecophysiology of the cape gooseberry, it was found that this typical Andean plant, in Colombia adapts to a wide altitudinal range of the tropical cold climate, that is, between 1,800 and 2,800 meters above sea level (m a.s.l.), with optimal medium temperatures between 13 and 16°C and base (minimum) temperatures for stem and fruit growth are relatively low, 6.3 and 1.9°C, respectively, however it does not withstand temperatures <0°C. Likewise, the Andean conditions of the tropics such as high solar radiation and day lengths <12 hours, rather short, favor the flower initiation. 1,500-2,000 hours year-1 of direct sunshine are the most favorable for the size, quality and ripening of the fruit. Under field conditions in Bogota, a photosynthesis rate of A = 10.545 μmol CO2 m-2 s-1 and light compensation point Ic = 13.645 μmol photons m-2 s-1 was measured. As a plant with an indeterminate growth habit, a constant supply of water is essential, while high amounts or heavy rains after a dry season cause cracking of the fruits, just as the plant does not tolerate waterlogging for more than 4 days. Cape gooseberry is classified as moderately tolerant to salinity and 30 mMol NaCl curiously promote growth, having mechanisms, such as increased antioxidant activity, to protect against saline conditions.
