摘要

农业生产质量及其通过施肥调节日益受到重视。然而，镁作为植物必需营养素的重要性已得到公认，但其在樱桃番茄上的应用尚未得到广泛的研究。本试验于2018年和2019年连续两季在室内通风条件下进行，研究不同Mg水平对滴灌条件下樱桃番茄生长、产量和果实品质的影响。在旁遮普红樱桃、旁遮普克萨樱桃和旁遮普索纳樱桃三个品种的营养阶段，在不同的时间间隔(1月、2月和3月的前两周)，以0.2、0.3和0.4%三个水平的硫酸镁进行叶面施用。测定了不同樱桃番茄品种的营养生长、产量及TSS、可滴定酸度等重要品质性状。旁遮普Kesar樱桃品种的总可溶性固形物(TSS)比旁遮普Sona樱桃高19%，比旁遮普Sona樱桃高10%，可滴定酸度分别比旁遮普红樱桃和旁遮普Sona樱桃高20%和9%。番茄果实TSS和可滴定酸度随Mg施用量的增加而增加。旁遮普索纳樱桃(6.96 kg/m2)的产量显著高于旁遮普红樱桃(5.63 kg/m2)，其次是旁遮普克萨尔樱桃(5.29 kg/m2)，叶面施用0.4%硫酸镁。

Response of cherry tomato (Lycopersicon esculentum var. cerasiforme) to different magnesium levels under naturally ventilated polyhouse

The quality of agricultural production and their modulation by fertilizer application has increasingly received attention. However, the importance of magnesium (Mg) as an essential plant nutrient is well established, but its application has not been studied extensively specially in cherry tomato. The experiment was carried out during two successive seasons of 2018 and 2019 in polyhouse under ventilated condition to evaluate the effect of different Mg levels on growth, yield and fruit quality of cherry tomato grown under drip irrigation system. Foliar application of magnesium sulphate was done at three levels (0.2, 0.3 and 0.4 %) on three cultivars viz., Punjab Red Cherry, Punjab Kesar Cherry and Punjab Sona Cherry during vegetative stage at different time interval (at the first fortnight of January, February and March). The vegetative growth, yield and important quality traits of different cherry tomato cultivars, including TSS, titratable acidity were determined. Punjab Kesar Cherry cultivar showed 19 % higher total soluble solids (TSS) than Punjab Sona Cherry and 10 % higher than Punjab Red Cherry and also showed titrable acidity 20 and 9 % higher than the cultivar Punjab Red Cherry and Punjab Sona Cherry, respectively. The TSS and titratable acidity in tomato fruits increased with Mg application rates. A significantly higher yield was recorded with Punjab Sona Cherry (6.96 kg/m2) as compared to Punjab Red Cherry (5.63 kg/m2) and followed by Punjab Kesar Cherry (5.29 kg/m2) with the foliar application of 0.4 % magnesium sulphate.
