EFFECT OF SPRAYING WITH SALICYLIC ACID AND CALCIUM CHLORIDE ON THE YIELD CHARACTERISTICS OF CORM AND CORMLETS FOR THREE CULTIVARS OF Gladiolus X hortulanus L

Abstract

the period from Apr. 11, 2019 to Sept. 30, 2019, with the aim of producing corm and cormlets in the summer of three varieties of Gladiolus X hortulanus L. They are: "Break of dawn" White flowers, "Espresso" with red flowers, and "Blue frost" with purple flowers after being treated with salicylic acid (SA) at 0 and 250 mg.l -1 , as well as treatment with calcium chloride in three concentrations: 0, 500 and 1000 mg.l -1 by spraying them on the foliage twice. The Factorial Experiment conducted by RCBD. The results show that the red cultivar recorded the largest weight of the corm was 28.98 g, its volume was 34.01 cm 3 , its diameter was 4.94 cm, and the number of cormlets was 12.33. per plant, the size of the cormlets is 13.52 cm 3 . Spraying with salicylic acid at 250 mg.l -1 had a significant effect in recording the largest values for the corm diameter and their volume. Treatment with calcium chloride at both concentrations 500 and 1000 mg.l -1 resulted in a significant increase in the corm weight, its diameter and the volume of cormlets. The treatment with calcium chloride at 1000 mg.l -1 caused to record the largest values for the number of cormlets are 9.53 cormlet. pl -1 , while the treatment with calcium chloride at 500 mg.l -1 increased of the corm volume is 27.68 cm 3 . The red cultivar plants treated with or without salicylic acid interact with calcium chloride at 500 mg.l -1 was gave the best grade of corms ranked 7.00 (Jumbo).

Effect of Calcium Chloride, Magnesium Sulfate and Maleic Acid Spraying on the Qualitative Traits of Two Varieties of Potatoes (Solanum tuberosum L.)

“…Calcium also plays a significant role in various vital processes within the plant, contributing to the formation of the middle lamella of the primary cell wall through the deposition of calcium pectates, thereby enhancing cell wall strength . The findings are consistent with what [24][25][26][27] have previously reported. Magnesium plays a role in carbohydrate metabolism and protein synthesis, enhancing the plant's resistance to stress.…”

Effect of Calcium Chloride, Magnesium Sulfate and Malic Acid Spraying on the Storage Characteristics of Two cvs. of Potato Tubers (Solanum tuberosum L.)

“…Many studies have proven that adding calcium before and after harvest significantly reduces the incidence of physiological damage, maintains crop quality and prolongs its life after harvest [17]. What was mentioned above is consistent with his findings [18][19][20][21][22]. Magnesium plays a role in carbohydrate metabolism and protein synthesis, as well as improving plant resistance to stress.…”
