“…It is clear that WS induced a negative effect on leaf biomass and fruit ripening, as confirmed by the reduction of leaf DW and the alteration of fruit-ripening processes. Our results are not consistent with those by other authors [38][39][40] but are in accordance with Khan et al [41]. The differences observed in the WS sensitivity may be due to the severity of drought.…”

Paramylon Treatment Improves Quality Profile and Drought Resistance in Solanum lycopersicum L. cv. Micro-Tom

Tomatoes, the most cultivated vegetables worldwide, require large amounts of water and are adversely affected by water stress. Solanum lycopersicum L., cv. Micro-Tom was used to assess the effects of β-(1,3)-glucan (paramylon) purified from the microalga Euglena gracilis on drought resistance and fruit quality profile. Plants were grown in an aeroponic system under three cultivation conditions: optimal water regimen, water scarcity regimen, and water scarcity regimen coupled with a root treatment with paramylon. Eco-physiological, physicochemical and quality parameters were monitored and compared throughout the lifecycle of the plants. Drought stress caused only a transient effect on the eco-physiological parameters of paramylon-treated plants, whereas physicochemical and biochemical parameters underwent significant variations. In particular, the fruits of paramylon-treated plants reached the first ripening stage two weeks before untreated plants grown under the optimal water regime, while the fruits of stressed untreated plants did not ripe beyond category II. Moreover, antioxidant compounds (carotenoids, phenolic acid, and vitamins) of fruits from treated plants underwent a two-fold increase with respect to untreated plants, as well as soluble carbohydrates (glucose, fructose, and sucrose). These results show that paramylon increases plant resistance to drought and highly improves the quality profile of the fruits with respect to untreated plants grown under drought stress.

“…These results indicate that water stress reduced the growth parameters due to their harmful effect on photosynthesis, which led to decrease in growth and development of plants, as a result of lake energy production in plant cell. Similar results were detected by Pervez et al (2009), Celebi (2014, and Khan et al (2015) Kheiralla et al (1997) and Kheiralla and Ismail (1995) on wheat.…”

“…The main effect of drought on plants is wilt. As a result of water shortage and this led to reducing growth and yield of plants (Khan et al, 2015). It is observed from the mean values of Figures 1 to 8 that there is a decrease in plant height cm, number of branches, number of cluster per plant, number of flowers per plant, number of fruits per plant, fruit set %, average weight of fruit, and fruit yield per plant by 21.4 and 22.8% in both seasons, respectively for plant height, 38.1 and 39.6 for number of branches, 26.5 and 26.9% for number of cluster, as for number of flower the decrease was 19.1 and 18.8%, in both seasons, respectively.…”

“…If plants do not get satisfactory precipitation or water system, the subsequent drought stress can lessen development more than all other environmental stresses. A plant reacts to absence of water by ending development and diminishing photosynthesis and other plant forms with a specific end goal to decrease water utilize (Khan et al, 2015). Drought and salinity are now far reaching in numerous locales and are relied upon to bring about genuine salinization of more than 50% of every single arable land by the year 2050 (Ashraf, 1994).…”

Field experiments were carried out during the period from 2013 to 2017 in the winter season at the experimental farm, Faculty of Agriculture, South Valley University, Qena, Egypt. Improvement yield and its attributes in Edkawy local cultivar via mass selection were done for three cycles. The unselected base population (C 0 ) and selected populations (C 1 , C 2 , and C 3 ) evaluated under two different water availability, favorable normal condition, and drought. The combined analysis of variance showed that significant differences between unselected and selected populations as well as highly significant among three cycles populations were detected all studied traits. Average fruit weight, number of flowers per plant, fruit yield per plant, number of cluster per plant, number of fruit per plant, number of branches per plant, fruit set percentage, and plant height have significantly increased a response to mass selection under unfavorable conditions. These increasing values for average fruit weight were 3.24, 6.90, and 12.09% in C 1 , C 2 , and C 3 , respectively. Furthermore, there was a significant increase in the number of fruits per plant in the first (2.45%), second (9.48%) and the third (13.72%) cycles under drought conditions. Fruits yield per plant was increased by 4.70, 12.44 and 21.40% for unselected and selected population, respectively. There was positive and highly significant correlation among all studied traits. In the respect to base populations under water stress treatments, results revealed that the use of mass selection for improvement yield and its components of tomato cv. Edkawy appeared to be increasing significantly for all studied traits.

“…Another research showed that in severe drought-stress conditions, there was a significant decrease in rubisco activity (Castrillo et al 2001;Calcagno et al 2011) and carbonic anhydrase (Sun et al 2016). Furthermore, a decreased photosynthesis rate due to limited incoming CO 2 caused by stomatal closure occurs in moderate and severe drought-stress tomatoes (Castrillo et al 2001;Khan et al 2015). Decreased morphological and physiological characters seen in plants on drought stress conditions will ultimately reduce the yield.…”

<p>The released lowland tomato cultivars are known for their resistance to plant diseases and high temperatures. The study aimed to identify the drought tolerance of lowland tomato cultivars based on the drought tolerant indices. The study was arranged in a split plot design, using seven lowland tomato cultivars (Zamrud, Permata F1, Ratna, Mirah, Tombatu F1, Tyrana F1, and Tymoti F1) as the main plot and watering (standard conditions and once every eight days as the drought conditions) as the subplot. Parameters observed were morpho physiological characters (plant height, leaf area, biomass, root length, root surface area, shoot root ratio, relative moisture content, membrane stability index, chlorophyll levels, and proline levels). The parameters observed in each character included the sensitivity stress index (SSI), stress tolerance index (STI), and yield stability index (YSI). Results showed that four cultivars (Tyrana F1, Tymoty F1, Mirah, and Tombatu F1) were drought tolerance, and three cultivars (Ratna, Permata F1, and Zamrud F1) were susceptible. The water stress decreased agronomic and physiological traits performance, but the drought-tolerant cultivars were less affected to the stress and produced higher fruit weight. The study implies that the drought-tolerant cultivars could be used as a promising source for drought tolerant genotypes.</p>
