Influence of micronutrients and growth regulators on the performance of cabbage quality

Abstract

in order to evaluate the performance of micronutrients (Zn and Fe) and growth regulators (Gibberellic acid and Naphthalene acetic acid) alone and their combinations applied as foliar spray for cabbage quality. The different levels of micronutrients were found significant on ascorbic acid and chlorophyll contents of cabbage head, maximum ascorbic acid (49.4 mg/100g fresh wt.) and chlorophyll content (0.412 mg/g fresh wt.) of cabbage head were recorded with treatment M 1 (zinc sulphate 0.5%). Among different levels of growth regulators, GA 3 @ 100 ppm recorded significantly highest ascorbic acid content (46.16 mg/100g fresh wt.), chlorophyll content (0.383 mg/g fresh wt.). While nonsignificant effect was recorded for total soluble solids on cabbage head. Among the interactions of micronutrients and growth regulators, the interaction M 1 G 2 recorded significantly the highest ascorbic acid content (57.99 mg/100g fr. wt.), chlorophyll content (0.505 mg/g fr. wt.) of cabbage head.

Effect of biofertilizers and micronutrients on growth and quality attributes of cabbage (<em>Brassica oleracea</em> var. <em>capitata</em> L.)

“…This increase in vitamin C content might be due to application of zinc and iron, both working as active carrier to enzymatic activities and enzymes catalyzing numerous biochemical reactions, including those neutralizing the effects of reactive oxygen species and various pathways of ascorbate synthesis in plants and resulted in to higher vitamin C content in cabbage head. Similar findings of increased vitamin C contents were reported by Kotecha et al (2016) [10] in cabbage and Singh et al (2018) [22] in broccoli.…”

Influence of Macro and Micronutrients on the Yield and Quality Attributes of Cauliflower (Brassica oleracea var. Botrytis L.) cv. “Pusa Sharad”

“…The obtained results were found to be inconsistent with the findings of Kumar et al [38], Mishra et al [39] in knol-khol, Yadav et al [40], Sharma and Kumar [41] in cauliflower, Roni et al [42] in broccoli, Zaki et al [31] in broccoli, and Kotecha et al [43] in cabbage. The increased ascorbic acid content appeared might be due to the application of micronutrients particularly boron which helps in carbohydrate metabolism.…”

The Implications of Growth-Regulating Substances on Growth and Yield Traits of Cauliflower

“…It was also reported that GA3 increasing plasticity of the cell wall followed by hydrolysis of starch to sugars which lowers the water potential of cell, resulting in the entry of water into cell causing elongation. These results are in accordance with other researchers viz., [7,8] in cauliflower; [9,10,11] in cabbage in cluster bean and [12] in Indian bean.…”
