Abstract

This study aims to enhance growth characteristics and quality parameters for tomato plants (Lycopersicon esculentum) by applying different doses of Crezacin (synthetic) and Energene (natural) as growth regulators instead of Chemical fertilization. A specific experiment has been carried out to study the effect of two types of plant growth regulators Crezacin: Active substances (475 g/L): Orth-o-cresoxyacetic acid triethanolammonium salt with applied doses (100, 200 and 300 ppm) and Energene: active substances (700 g/kg) humic acid with applied doses (250, 500 and 700 ppm) on growth and physiological characteristics of tomato plants (Kendras F1). Both Crezacin and Energene were applied three times (Soaking tomato seeds for 24 hours before sowing, spraying on plants at 35 DAP, spraying on plants at 70 DAP). Application of humic acid “Ener-700” increased plant height (78.0 cm), number of leaves/ plant (57.8), fresh weight (250.2 g), dry weight (75.1 g) of arial parts, flowers number (48.1), fruits number (35.1) and fruit weight (64.0 g). Also using “ Ener-700” improved tomato fruit’s quality by enhancing level of dry matter (7.6 %), sugar contents (5.8 oBrix), Ascorbic acid (26.9 mg 100 g-1), Maturity Index (12.61) and Taste Index (1.09), while level of nitrate rose by increasing humic acid and the maximum level (22.0 mg kg-1) obtained from Ener-700. Applying Ener-500 gave the maximum titratable acidity (0.48%) and carotenoids contents (4.89 mg 100 g-1)

百忧解和腐殖酸对番茄生长和生理特性的影响

本研究旨在通过施用不同剂量的克忧锌（合成）和Energene（天然）作为生长调节剂，而不是化学施肥，来提高番茄（Lycopersicon esculentum）的生长特性和质量参数。本试验研究了两种植物生长调节剂克扎辛：活性物质（475 g/L）：施用剂量（100、200和300 ppm）的邻甲氧基乙酸三乙醇胺盐和施用剂量（250、500和700 ppm）的Energene:活性物质（700 g/kg）腐殖酸对番茄生长和生理特性的影响（肯德拉斯F1）。Crezacin和Energene都施用了三次（播种前将番茄种子浸泡24小时，以35DAP喷洒在植物上，以70DAP喷洒到植物上）。施用腐殖酸“Ener-700”可增加株高（78.0cm）、单株叶数（57.8）、鲜重（250.2g）、干重（75.1g）、花数（48.1）、果数（35.1）和果重（64.0g）。使用Ener-700可提高番茄果实的干物质（7.6%）、含糖量（5.8oBrix）、抗坏血酸（26.9mg/100g-1）、成熟度指数（12.61）和味觉指数（1.09），从而改善番茄果实的品质。应用Ener-500可获得最大可滴定酸度（0.48%）和类胡萝卜素含量（4.89 mg 100 g-1）
