“…It was clear that irrigation at 100% ETc was the most effective treatment in this concern. Our results are line with Agina et al (2021) on rosemary. The positive impact of glutamic acid on macro and micro nutrients in plants indicated that, spraying with glutamic acid at 10mM led to maximum increase of N, P, K, Cu and Fe by 35.79 and 34.05%, 50 and 40%, 35.38 and 39.53%, 32.88 and 30.92%& 37.13 and 31.79% for 1 st and 2 nd cuts, respectively of the first season as compared to untreated plants (Table 10 and 11).…”

The present study was conducted during 2019 and 2020 seasons in the Experimental Farm of EL-Quassassin, Horticulture Research Station, Ismailia Governorate, Egypt to investigate the effect of foliar application of glutamic acid on sweet basil (Ocimum basilicum, L. var. Grand Vert) plants grown under different irrigation levels. A split-plot design was used, the main factor was irrigation levels (50%, 75% and 100% of crop evapotranspiration (ETc)), while the glutamic acid at (0, 5 and 10 mM) were assigned in sub-factor. The results showed that irrigation rates had a significant effect on most aspects for the two cuts in both seasons. Where the irrigation level at 100% ETc was the most effective treatment. The foliar spraying with glutamic acid on sweet basil plants had a positive effect on plants, it significantly increased growth, yield parameters and chemical composition in treated plants as compared to un treated ones. Regarding the interaction treatments, it was worth to be mentioned that, there was insignificant difference, when spraying with glutamic acid under irrigation level at 100 or 75% ETc in most studied traits. Also, the results of Gc-Ms analysis of sweet basil volatile oil indicated that, the highest linalool content which consider the main component was produced with irrigation level at 75% ETc +spraying with 10mM glutamic acid. Furthermore, glutamic acid foliar application improve irrigation water utilization efficiency (IW.Ut.E). The highest IW.Ut.E was recorded at the interaction of irrigation level at 50% ETc with foliar application by10mM glutamic acid.

Адаптация видов рода Gleditsia и Robinia во многом зависит от состояния их водного режима в период вегетации. Способность удерживать и экономно расходовать воду в засушливых условиях является защитно-приспособительной функцией у интродуцированных видов. Степень засухоустойчивости различных видов рода Gleditsia и Robinia оценивалась по состоянию их водного режима в засушливый период. Исследования проводились по многолетним данным, выделяя оптимальные по влагообеспеченности и засушливые годы. В качестве объекта изучения являлись виды: R. viscosa, R. neomexicana, R. pseudoacacia, R. hispida, G. texana, G. сaspica и G. triacanthos, произрастающие в кластерных дендрологических коллекциях ФНЦ агроэкологии РАН (кадастр. № 34:34:000000:122, 34:34:060061:10; кадастр. № 34:36:0000:14:0178). Цель – сравнительная оценка адаптации видов рода Gleditsia и Robinia к особенностям водного режима в условиях каштановых почв. Установлено что наивысшие показатели водоудерживающей способности у рода Robinia имеют типичные представители и декоративные формы R. neomexicana. Низкой водоудерживающей способностью отличается R. viscosa. Содержание воды в листьях G. сaspica выше, чем у G. texana. Оводненность побегов уменьшается в течение вегетационного периода, в начале лета она находится в пределах 64,5 – 71,0 % (Gleditsia) и 69,4 – 70,2 % (Robinia). К концу вегетационного периода оводненность падает на 11,3 – 15,9 %. Максимальное снижение оводненности наблюдалось у G. texana (15,9 %). В родовом комплексе Robinia снижение оводненности наибольшее наблюдалось у R. pseudoacacia – на 10,2 – 14,7 %. Длительная засуха и высокая среднесуточная температура вегетационного периода 2020 г. ухудшила показатели водного потенциала видов рода Gleditsia и Robinia. Adaptation of species of the genus Gleditsia and Robinia largely depends on the state of their water regime during the growing season. The ability to retain and economically use water in arid conditions is a protective and adaptive function in introduced species. The degree of drought resistance of various species of the genus Gleditsia and Robinia was assessed by the state of their water regime during the dry period. The studies were conducted based on long-term data, highlighting optimal moisture availability and dry years. The following species were studied: R. viscosa, R. neomexicana, R. pseudoacacia, G. texana, G. caspica and G. triacanthos, growing in cluster dendrological collections of the Federal Research Center of Agroecology of the Russian Academy of Sciences (Cadastre. № 34:34:000000:122, 34:34:060061:10; Cadastre No. 34:36:0000:14:0178). The aim is a comparative assessment of the adaptation of species of the genus Gleditsia and Robinia to the peculiarities of the water regime in the conditions of chestnut soils. It was found that the highest indicators of water-holding capacity in the genus Robinia have typical representatives and decorative forms of R. neomexicana. R. viscosa has a low water-holding capacity. The water content in the leaves of G. caspica is higher than that of G. texana. The hydration of shoots decreases during the growing season, at the beginning of summer it is in the range of 64.5 – 71.0% (Gleditsia) and 69.4 – 70.2% (Robinia). By the end of the growing season, the water content drops by 11.3 – 15.9%. The maximum decrease in hydration was observed in G. texana (15.9%). In the Robinia generic complex, the greatest decrease in hydration was observed in R. pseudoacacia – by 10.2 – 14.7%. Prolonged drought and high average daily temperature of the growing season in 2020 worsened the indicators of the water potential of species of the genus Gleditsia and Robinia.
