“…Such a significant increased in number of branches is due to foliar application of zinc and iron which might have increased vegetative growth parameters of plant by involving in tryptophan and chlorophyll synthesis, which in turn helps to maintain polarity and apical dominance of plant. Similar results were obtained by earlier workers [6,16].…”

An experiment was conducted at the Department of Soil Science and Agricultural Chemistry, Tamil Nadu Agricultural University, Coimbatore during 2021-2022 to evaluate the effect of zinc and iron on growth, quality, yield and biochemical trait of marigold cv. Local Orange. The experiment was laid out in completely randomized design (CRD) with eight treatments and three replications. The eight treatments included an untreated control (T1) , 100% RDF (T2) , along with RDF soil application of FYM enriched ZnSO4 and FeSO4 @ 10 and 15 kg ha-1 respectively (T3), along with RDF soil application of FYM enriched ZnSO4 and FeSO4 @ 15 and 20 kg ha-1 respectively (T4), along with RDF soil application of FYM enriched ZnSO4 and FeSO4 @ 20 and 25 kg ha-1 respectively (T5), along with RDF foliar spray of ZnSO4 and FeSO4 each @ 0.5% (T6), along with RDF foliar spray of ZnSO4 and FeSO4 @ 0.5 and 1.0 % respectively (T7) , along with RDF foliar spray of 1.0 % liquid multi micronutrient (T8). The effect was assessed on growth, quality, yield and xanthophyll content in marigold flower. The results revealed that foliar application of ZnSO4 and FeSO4 each @ 0.5 % along with RDF at 20DAT and 35DAT recorded maximum plant growth, flower quality and flower yield. On xanthophyll content foliar application of 1.0 % liquid multi micronutrient along with RDF produced significant effect compared to control. The present study revealed that the integrated application of zinc and iron fertilizer significantly improved the growth, yield, quality of marigold crop. However both soil application and foliar spray of zinc and iron showing significant effect compared to control for better productivity and flower quality of marigold.

“…According to Chakrabarty et al 23 , the activity of catalase in cut chrysanthemums kept increasing until full bloom and later fell dramatically. In gladiolus, the fluctuations in the catalase activity were observed during flowers senescence 34 . In intact cosmos flowers, the activity tripled in six days of the experiment while in cut control flowers it dropped, similarly to flowers held in both 8-HQC solutions.…”

To prolong their vase life, cut flowers are commonly kept in holding solutions. These must include a biocide to retard bacterial growth. In this study, the effect of nanosilver (NS) on certain aspects of senescence in cut garden cosmos (Cosmos bipinnatus) flowers was compared to that of the commonly used 8-hydroxyquinoline citrate (8-HQC). In combination with sucrose, both biocides prolonged cosmos vase life but did not prevent the occurrence of stem blockages. NS was more effective in limiting a reduction in endogenous soluble carbohydrates. The malondialdehyde (MDA) contents increased in senescing ray florets, both in intact and control cut flowers held in water. Both biocides were comparably effective in limiting this effect. The hydrogen peroxide content tripled in intact flowers but dropped in flowers held in water or the 8-HQC solutions; in flowers kept in NS solutions its increase was moderate. Also, the catalase activity increased in intact flowers but dropped in all cut flowers. Both biocides had similar effects on the enzyme activity, in both pure solutions and with sucrose. Most of these parameters were not significantly correlated with vase life. Overall, the effect of nanosilver on senescence in cut cosmos flowers was similar to that of 8-HQC. Growing consumer interest in new cut flower species drives field production of seasonal, locally grown flowers 1. Garden cosmos-also known as lace cosmos because of its delicate pinnate foliage-is gaining popularity not only as a garden or a bedding plant but also as cut flowers. Diversity of forms and colors make the species popular among florists and customers but its postharvest longevity is short, usually 4-6 days 1. However, this longevity can be doubled by making use of the so-called flower food, i.e. holding solutions containing a biocide and a sugar 2. These two components are crucial in extending the vase life as they delay flower senescence. Senescence usually occurs faster in cut flowers than in those left on mother plants. This was clearly illustrated by de Stigter 3 on cut and intact hydroponically grown 'Sonia' roses observed under the same environmental conditions and confirmed by subsequent studies on rose 4 , lilac 5 , clematis 6 and peony 7. The processes of senescence are accelerated mainly by water stress caused by improper water balance in cut stems. Such stems, even when held in water, are unable to absorb sufficient amounts of water to compensate for the transpiration losses. Vessels in cut stems become obstructed by blockages of various nature, with the presence of microbes in vase water being the most common 8. For this reason, biocides in holding solutions are crucial for the postharvest longevity of cut flowers. For over a half a century the esters of 8-hydroxyquinoline have been used as potent biocides, in mixtures with sucrose. This is called the standard preservative 9. Nanosilver [NS] has emerged as a new biocide for cut flowers after the use of toxic silver nitrate had been outlawed 10. Though it was enthusiastically accepted in ...

“…However, excessive amounts can cause plant toxicity (Chaney 1993), which also exerts a specific impact on the Calvin cycle and optical system activities (Van Assche and Clijsters 1986). Zinc can activate several antioxidant enzymes, such as SOD, POD, and CAT (Jat et al 2007, Saeed et al 2013. Fernàndez-Martínez et al (2014) showed that plant photoprotection and antioxidant capacity increase with increasing Zn concentration; however, high concentrations of Zn produce high toxicity, which can reduce crop biomass, decrease photosynthetic pigment content, and damage the photochemical processes and photosynthesis.…”

This study aimed to evaluate the effects of Zn on the growth safety and activity of carbonic anhydrase (CA) in foxtail millet (Setaria italica L.). The photosynthetic characteristics, CA activity, and relative gene expression of different varieties of millet at the seedling stage were studied by spraying Zn solution under pot experiment and indoor culture conditions. Results showed that spraying low-concentration Zn solution (20, 40, and 60 mg L −1) reduced malondialdehyde content and intercellular CO2 concentration (Ci) but increased antioxidant enzyme activity, pigment content, and photosynthetic gas-exchange parameters (net photosynthetic rate, stomatal conductance, transpiration rate, except for Ci); meanwhile, spraying high Zn concentration (80 and 100 mg L −1) exerted opposite effects. The optimal growth of millet was achieved when the Zn concentration was 40 mg L −1. At this concentration, CA activity increased and β-CA family expression was upregulated, which exerted little or no effect on other CA families. Compared to Zhangzagu 10 (zinc-resistant variety), Jingu 21 (zinc-sensitive variety) showed a more significant change. This study may serve as a reference for further research on the function of CA and physiological processes, such as photosynthesis in millet, and a theoretical basis for the effective use of Zn fertilizer in millet.
