Hibiscus Syriacus

Salt injury was induced by 5% (w/v) NaCl drenching on Hibiscus hamabo Sieb. & Zucc. and H. syriacus L. seedlings. Total chlorophyll content of H. hamabo was higher than that of H. syriacus. Uniconazole (0.0, 0.5, 1.0, and 5.0 mg·liter–1) treatment increased and 25- or 50-mg·liter–1 GA3 treatment decreased chlorophyll content of H. hamabo. Total chlorophyll content of H. syriacus was not affected by uniconazole or GA3. Total carbohydrate content of H. syriacus was more accumulated than that of H. homabo. Total carbohydrate content of H. hamabo was more decreased than that of H. syriacus by Ca (13.35 or 133.5 mM), uniconazole, or GA3 in relation to total carbohydrate contents. Protein contents of H. hamabo were higher than those of H. syriacus. Uniconazole or GA3 increased those of H. hamabo and decreased those of H. syriacus. Peroxidase activity of H. hamabo was higher than that of H. syriacus. Uniconazole decreased that of H. hamabo and increased that of H. syriacus. GA3 or Ca (13.35 mM) treatment increased that of both species. ATPase activity of H. hamabo was higher than that of H. syriacus. Uniconazole (5 mg·liter–1), GA3, or Ca decreased that of H. hamabo increased that of H. syriacus.

Variations in the photosynthetic pigments and total carbohydrate contents of needles of different age classes (current-year, 1-year-old, 2-year-old and 3-year-old) of Pinus nigra subsp. pallasiana (Lambert) Holmboe trees in a young natural stand were investigated during the growing season. In current-year needles, total carbohydrate content was lower during June and July when the needle growth continued than in older age classes, but it was similar to other age classes in the months of August to October. Seasonal patterns of variations in total carbohydrate content were almost similar in 1-, 2-, and 3-year-old needles. Chlorophyll and carotenoid contents increased from May to June, remained relatively constant or declined slightly during summer and autumn in 1-, 2-, and 3-year-old needles. In October, the pigment content was highest in 1-year-old needles, and lowest in 3-year-old needles. Our study indicated that total carbohydrate and pigment contents were affected by needle age classes and seasons.

Keeping quality and length of vase life are important factors for evaluation of cut flowers quality, for both domestic and export markets. Studding the effect of pre- and post-harvest salicylic acid applications on keeping quality and vase life of cut alstroemeria flowers during vase period is the approach taken. Aqueous solutions of salicylic acid at 0.0 (with distilled water), 1, 2 and 3 mM were sprayed to run-off (approximately 500 mL per plant), about two weeks before flowers harvest. The cut flowers were harvested in the early morning and both of cut flowers treated (sprayed) and untreated were kept in vase solutions containing salicylic acid at 0.0 (with distilled water), 1, 2 and 3 mM. Sucrose at 4% was added to all treatments as a base solution. The changes in relative fresh weight, water uptake, water loss, water balance, total chlorophyll content and vase life were estimated during vase period. The results showed that the relative fresh weight, water uptake, water balance, total chlorophyll content and vase life decreased significantly while the water loss increased significantly during experiment for all treatments. A significant difference between salicylic acid and control treatments in all measured parameters is observed. During vase period, the salicylic acid treatments maintained significantly a more favourable relative fresh weight, water uptake, water balance, total chlorophyll content and supressed significantly water loss, as compared to control treatment. Also, the results showed that the using salicylic acid increased significantly the vase life cut alstroemeria flowers, over control. The highest values of measured parameters were found when plants were treated by pre + post-harvest application of salicylic acid at 3 mM. The result revealed that the quality attributes and vase life of cut alstroemeria flowers were improved by the use of salicylic acid treatment.

Persian lime is economically important for Mexico. However, the disease known as Huanglongbing (HLB) causes chlorosis symptoms in the foliage that affect the growth and decreases the yield of the trees. The expression of chlorosis symptoms is associated with starch accumulation and inhibition of antioxidant activity. The objective of the present work was to determine the effect of the application of three resistance elicitors on the expression of three antioxidant genes and on starch and chlorophyll content in Persian lime trees with HLB. Salicylic acid (SA), jasmonic acid (JA) or gamma-aminobutyric acid (GABA) were applied every eight days for nine weeks using a completely randomized design and a one-way ANOVA was performed for the analysis. Expression of APX, CAT and SOD genes was quantified at week nine at four different times. Starch and total chlorophyll content was estimated every three weeks by spectrophotometric methods. The application of the elicitors significantly increased the expression of the three genes, with SA and GABA generating the greatest increase at different times of application. No difference was found in starch and total chlorophyll content at most of the times evaluated. The use of resistance elicitors is promising in the management of HLB in plots already infected, seeking to extend the productive life of the orchards and thus counteract the economic losses caused by HLB.

Water spinach (Ipomoea reptans Poir) had been identified as a nutritious vegetable with high demand in Indonesia. Besides, this plant also has been evidenced to play an important role in environmental cleaning as phytoremediator. The study about the effect of organic fertilizers on the growth and yield of water spinach (Ipomoea reptans Poir) has been conducted in the Green House of Biology Department, Faculty of Mathematics and Natural Sciences, Universitas Negeri Medan. The study aims to investigate the most effective type of fertilizers and the dose for water spinach’s (Ipomoea reptans Poir) growth and yield. A Completely Randomized Factorial Design was designed for the experiment with two factors and three repetitions. The first factor is the type of fertilizer (chicken manure, cow manure, and compost), and the second factor is the dose of the fertilizer (1:1, 2:1, and 3:1). The parameters such as plant height, number of shoots, number of leaves, fresh weight, dry weight, leaf’s total chlorophyll content, and water content were measured to evaluate plant growth and yield. The General Linear Model used SPSS 21 programs was applied to analyze the collected data. Study results revealed that cow manure increased plant growth and yield significantly with dose 2:1 as the finest treatment, followed by dose 3:1. Cow manure also increased total chlorophyll content (8.0574c mg. L-1), with the most suitable dose was 2:1 (8.2807 mg. L-1). The plant’s water content tended to be high in chicken manure (93%), and the lower water content was in cow manure with dose 3:1 (87.5%).

The study was conducted at the experimental farm of Mustafa Kemal University, Dörtyol, Turkey during the 2010 and 2011 growing seasons. The aim of this study was to investigate the effect of ‘Troyer’ and ‘Carrizo’ citranges (Poncirus trifoliata Raf. × Citrus sinensis Osb. var. ‘Troyer’ and ‘Carrizo’), and common sour orange (Citrus aurantium L. var. common), rootstocks on the seasonal variation of carbohydrate content in the leaves of cvs. ‘Fremont’, ‘Nova’, and ‘Robinson’ mandarin. The seasonal variation of carbohydrate content of the three cultivars budded on different rootstocks was nearly same. Soluble carbohydrate concentration showed a continuous decrease from January to mid or late-summer, and then slowly began to increase after early autumn till winter. The sucrose was the dominant soluble carbohydrate in leaves. The seasonal evolution of starch content in leaves increased initially during January to March, and then decreased in April. The starch concentration showed a continuous decrease slowly until the mid-autumn, and then accumulation began during late-autumn and winter. The total carbohydrate content differences among the rootstocks were significant, but the content was changed among the cultivars and according to the season. The change in the total carbohydrate content of leaf tissues showed a strong similarity in cultivars budded on different rootstocks throughout the year. The total carbohydrate content reached their lowest levels in July for cv. ‘Robinson’, in August for cv. ‘Fremont’ and cv. ‘Nova’. The total carbohydrate content in leaves increased from the mid- or late-summer to winter. It is suggested that the seasonal variation of carbohydrate content in plant tissues can be considered during fertilization program in mandarin trees.

Heat and drought are among the major obstacles confronting crop production under climate change. The present study was conducted to evaluate 50 diverse wheat genotypes for cell membrane stability (CMS) and chlorophyll content at seedling and anthesis stages under heat and drought stress conditions, to understand the effect of the two abiotic factors and to find promising genotypes for future breeding. Experiments were conducted in the glasshouse (seedling stage) and the field (anthesis stage). Analysis of variance showed significant variation (P ≤ 0.05) for all of the traits at seedling and anthesis stages. High levels of broad-sense heritability and genetic advance at 5% selection intensity indicated the presence of a high genetic component of variation and potential for genetic improvement through selection among the existing genetic variation. CMS showed a significant positive correlation with 1000-grain weight (TGW) under heat and drought conditions at both seedling and anthesis stages. Chlorophyll a/b ratio at seedling stage exhibited a significant negative correlation (r = –0.39, P < 0.05) with TGW under heat stress. Total chlorophyll content was significantly (r = 0.42, P < 0.05) correlated with TGW under heat stress at anthesis. Genotypes ETAD248 and ETAD7 showed the highest CMS and TGW values, whereas their chlorophyll a/b values were lowest, at both seedling and anthesis stages under heat and drought stress conditions. Higher CMS and total chlorophyll content, and lower chlorophyll a/b, were found to be useful indicators to identify genotypes with high TGW under heat and drought stress conditions. This study indicated the possibility of using seedling resistance as an indicator for later stage response in breeding for heat and drought resistance. The resistant genotypes identified can be used as potential germplasm in breeding programs.
