Response of Night-Blooming Jessamine (Cestrum nocturnum L.) Plants to Phosphorus-Zinc Relation. 1-Growth, Flowering and Uptake of Phosphorous and Zinc.

Abstract

Night blooming jessamine (Cestrum nocturnum L.) plants were grown in pots to study P-Zn relations as the behavior of both P and Zn affecting the absorption of each other by the plant that reflect on growth and flowering. Phosphorus was applied to soil at rates of 0 to 560 ppm with addition of Zn at rates of 0 to 48 ppm.Greatest plant height, branch number, flowering (earliness and duration) and maximum dry weight accumulation in the different plant parts were occurred by the combination of 280 ppm P and 24 ppm Zn applied. In the absence of added P, shoot/root ratio was increased with increasing Zn level up to 24 ppm. Phosphorus at 70 and 560 ppm with Zn levels, this ratio was a nearly constant, while P at 140 and 280 ppm with low Zn level added, the ratio was decreased.Total uptake of P and Zn indicated that P and Zn fertilization had altered the uptake of both nutrients by the plant. Total uptake of P was increased by high P and low Zn. Total Zinc uptake varied opposite to that of P. The maximum of P and Zn were obtained by P 280 Zn 24 as the greatest growth and flowering occurred.

Investigation the role of Plasma-Activated Water Washing and Storage on the Shelf Life of Cestrum nocturnum L. (Night-Blooming Jasmine) Flowers

“…The calyx, the green part at the bottom with five teeth, is smaller (about one-third) compared to the main flower part (corolla) measuring 2.0-2.5 cm. The corolla lobes, or petal edges, are approximately 5-6 mm long, somewhat blunt, and can either stick up or spread out (4,8). The flowers are valued for their uses in aromatherapy, ornamentation, decoration, antimicrobial properties against bacteria, fungi, viruses, food preservation, and traditional medicinal applications, especially in South Asian countries like China, India, Bangladesh, and Thailand, etc.…”

“…This phenomenon explains the observed rise and fall behavior in H 2 O 2 and dissolved O 3 concentrations. Initially, their concentrations increase with time, and later, they decrease due to the reactions outlined in equations(7)(8)(9)(10)(11).…”

“…substantially higher compared to NO 2 ˉ ions (1.4 mg L -1 at 30 minutes). This discrepancy is attributed to the higher stability of NO 3 ˉ in PAW compared to other dissolved species like NO 2 ˉ, H 2 O 2 , and dissolved O 3 , as indicated in equations(7)(8)(9)(10)(11) (27, 37, 43, 49, 59- …”
