摘要: 为研究鱼蛋白水解物对番茄幼苗生长及光合特性的影响,以番茄CR(Solanum lycopersicum var. cerasiforme)品种为试验材料,设置5种不同浓度的鱼蛋白水解物处理,测定番茄幼苗株高、根长、生物量、根系活力、营养指标、抗氧化酶活性、光合指标、叶绿素含量和叶绿素荧光参数,以期明确适宜番茄幼苗生长的鱼蛋白水解物浓度。结果表明,与对照相比,T1、T2、T3、T4(鱼蛋白水解物稀释2 000、1 600、1 200、800倍)处理促进了番茄幼苗生长。其中T3(稀释1 200倍)处理促进番茄幼苗生长效果最佳,其株高、茎粗、根长、地上部鲜重、地下部鲜重和根系活力显著(p<0.05)高于其他处理和对照,可溶性糖和可溶性蛋白含量也较对照显著提升。T3处理下番茄幼苗过氧化物酶(POD)、超氧化物歧化酶(SOD)活性显著提升,丙二醛(MDA)含量显著降低,抗氧化、抗逆能力增强。与对照相比,T3处理下番茄幼苗叶绿素总含量和净光合速率分别增加了22.16%和23.57%。同时,T3处理显著提高了番茄幼苗PSⅡ最大光化学效率(Fv/Fm)、PSⅡ实际光化学效率(ΦPSⅡ)、非光化学猝灭系数(NPQ)。因此,鱼蛋白水解物稀释1 200倍处理能显著促进番茄幼苗生长,增强其光合特性。本研究为番茄育苗提供了一种高效、可持续的施肥方法,具有一定的应用价值和推广前景,为鱼蛋白水解物在蔬菜育苗中的应用提供了理论依据。

Abstract:

In order to study the effects of fish protein hydrolysate on the growth and photosynthetic characteristics of tomato seedlings, CR (Solanum lycopersicum var. Cerasiforme) variety was used as experimental material, and five different concentrations of fish protein hydrolysate treatments were set up in this study. The plant height, root length, biomass, root activity, nutritional index, antioxidant enzyme activity, photosynthetic index, chlorophyll content and chlorophyll fluorescence parameters of tomato seedlings were measured to determine the appropriate concentration of fish protein hydrolysate for the growth of tomato seedlings. The results showed that compared with the control, T1, T2, T3 and T4 treatments(fish protein hydrolysate diluted 2 000, 1 600, 1 200, 800 times) promoted the growth of tomato seedlings, and T3 treatment(diluted 1 200 times) had the best effect on the growth of tomato seedlings, with its plant height, stem diameter, root length, aboveground fresh weight, underground fresh weight, and root vitality were significantly(p<0.05) higher than those in other treatment groups and control. Compared with the control, the content of soluble sugar and soluble protein also significantly increased. In the T3 treatment, the activities of POD and SOD were significantly increased, the MDA content was significantly decreased, and the ability of antioxidant and stress resistance was enhanced. Compared with the control, total chlorophyll content and photosynthetic rate of tomato seedlings in T3 treatment were increased by 22.16% and 23.57%, respectively. At the same time, it was found that T3 treatment significantly improved the PSⅡ maximum photochemical efficiency (Fv/Fm), the actual photochemical efficiency (ΦPSⅡ) and the non-photochemical quenching coefficient (NPQ) of tomato seedlings. Therefore, diluting 1 200 times the fish protein hydrolysate treatment can significantly promote the growth of tomato seedlings and enhance plant photosynthetic characteristics. This study provides an efficient and sustainable fertilization method for tomato seedling cultivation, which has application value and popularization prospect, and provides a theoretical basis for the application of fish protein hydrolysate in vegetable seedling cultivation.
