Abstract

An experiment was conducted at Woodhouse farm, Horticultural Research Station, Ooty, during October 2017 to March 2018 to quantify the impact of elevated ozone and ozone protectant spray on plant growth, nutrients, biochemical and yield properties of turnip crop. The experiment was laid out in a factorial completely randomized block design and was replicated thrice. Elevated ozone exposure on turnip significantly reduced the plant height, tuber size, tuber weight, chlorophyll ‘a,’ chlorophyll ‘b’ and total chlorophyll content as well as the nutrient content of plant, viz., total nitrogen, total potassium, total manganese, iron, zinc and copper, also affected. Elevated ozone exposure significantly increased the antioxidant enzyme activity like catalase and peroxidase activity in addition to increment in total phosphorus content in leaf tissues. However, ozone protectants played a major role in nullifying the tropospheric ozone effect on growth and development, physiological traits and yield of turnip while tested with panchagavya performed better followed by neem oil and ascorbic acid.

高浓度臭氧及臭氧保护剂对芜菁生长、养分、生化及产量特性的影响

本试验于2017年10月至2018年3月在乌蒂园艺研究站伍德豪斯农场进行，旨在量化臭氧浓度升高和臭氧保护剂喷洒对萝卜植株生长、养分、生化和产量特性的影响。试验采用因子完全随机区组设计，重复3次。臭氧暴露量的增加显著降低了萝卜的株高、块茎大小、块茎重量、叶绿素a、叶绿素b和总叶绿素含量，以及植株的全氮、全钾、全锰、铁、锌和铜的营养含量。高臭氧暴露显著提高了叶片过氧化氢酶、过氧化物酶等抗氧化酶活性，并显著增加了叶片组织中总磷含量。臭氧保护剂在消除对流层臭氧对萝卜生长发育、生理性状和产量的影响方面发挥了主要作用，其中以潘查加味为佳，其次是楝油和抗坏血酸。
