Pre-harvest foliar application of humic acid, salicylic acid and calcium chloride to increase quantitative and qualitative traits of Lilium longiflorum cut flowers

Abstract The experiment was carried out on Papaya seedlings (2 months old) to determine the effect of humic acid (HA) and Salicylic acid (SA) on seedlings growth under local environmental conditions of in a private orchard in Diyala governorate. Humic acid (HA) sprayed at 4 concentrations (0, 1, 2 and 3%), whereas Salicylic acid (SA) was used at three concentrations (0, 200 and 400 mg.L-1). The results showed that spraying with the high concentrations of both acids gave the best results in most studied traits, in addition these treatments decreased significantly leaves proline content.

In order to amend the harmful effect of soil salinity stress in common sage plants by foliar spray with salicylic acid (SA) and humic acid (HA), two pot experiments were conducted at the Nursery of ornamental plants, Agric. Fac., Zagazig Univ., Sharkia Governorate, Egypt in lath house during the two winter consecutive seasons of 2018/2019 and 2019/2020. The aiming of this work was to investigate the effect of foliar application treatments i.e., sprayed with distilled water (control), 200 ppm salicylic acid (SA), 750 ppm humic acid (HA), 1500 ppm HA, 200 ppm SA+750 ppm HA and 200 ppm SA+1500 ppm HA under various soil salinity levels (0.0, 1000 and 2000 ppm) as well as their combinations on yield components, salt resistance index and volatile oil production as well as some chemical constituents of Salvia officinalis plants. These experiments were arranged in a split-plot design with three replicates. The main plots were occupied by different soil salinity levels and the sub plots were entitled to different salicylic acid and humic acid acids concentrations. The obtained results referred to that herb fresh and dry weights per plant as yield components, volatile oil percentage and volatile oil yield per plant as volatile oil production as well as salt resistance index (%) were recorded. Also, total carbohydrates percentage and total chlorophyll (SPAD unit) in sage leaves was determined. Results showed that using soil salinity levels (1000 and 2000 ppm) significantly decreased yield components, volatile oil yield per plant, total carbohydrates percentage and total chlorophyll content compared to control. In contrast, increasing soil salinity levels gradually increased volatile oil percentage and proline content. In addition, the maximum values of the most of all above mentioned traits were achieved by treating sage plants with 200 ppm SA+1500 ppm HA. Generally, it could conclude that 200 ppm SA+750 or 1500 ppm HA, showed a uniform influence in qualifying of common sage y

An Experiment carried out in Al-Yarmook Area in Baghdad for the growing season 2014 to study the effects of foliar application of Salicylic acid and Humic acid on Vincristine and NPK content in Catharanthus roseus. A factorial experiment was applied including two factors according to The Complete Randomized Block Design, the first factor included four levels of salicylic acid 0, 25, 50, and 100 mg.L-1 which were represented with S0, S1, S2, and S3 sequentially, the second factor included three levels of Humic acid 0, 0.75, and 1.5 ml.L-1 and were represented with O0, O1, and O2 sequentially to make up 12 factors in total that were distributed randomly upon three replicates and each experimental unit included 8 plants. The results were analyzed using Genestat and the differences were tested according to (LSD) with a level of probability 5% and the results were as follows: Vincristine levels increased in the leaves of Catharanthus roseus as a result of foliar application of Salicylic acid and Humic as well NPK levels in leaves. Vinblastine was not detected in all treatments. The interaction effect between 100 mg.L-1 Salicylic acid and 1.5 ml.L-1Humic acid had an exceeding effect for all the studied parameters. It may be concluded that Salicylic and Humic acid may be used to increase Vincristine alkaloid content in Periwinkle plants at the levels 100 ml.L-1 and 1.5 mg.L-1 subsequently.
