Abstract

Abstract The effects of foliar spraying of sodium nitroprusside (SNP) and putrescine (Put) on rose cv. Avalanche were investigated. This experiment was conducted in a factorial trial with two factors, including SNP at four levels of 0, 50, 100 and 200 μM and putrescine at four concentrations of 0, 1, 2, and 4 mM with three replications in hydroponic conditions in the greenhouse. Some of the recorded traits included the number of leaves plant-1, leaf area, fresh and dry leaf weight, as well as determination of soluble sugars, and total protein. Also, in the post-harvest stage, the recoded traits included malondialdehyde (MDA) content, relative fresh weight, and vase life. SNP at a concentration of 100 μM was found to improve morphological traits including fresh and dry weight of leaf (4.3 and 1.4 g, respectively) compared to the control. It also increased total protein (0.85 mg g-1 FW), decreased postharvest MDA content (0.32 µM g-1 FW), and increased vase life (23.66 days) at 100 μM level, and increased leaf area (7671 mm2) and flower relative fresh weight (27.65%) at 200 μM level. Among different rates of putrescine, 4 mM putrescine was associated with higher leaf area (8056.7 mm2), fresh and dry leaf weight (4.3 and 1.3 g, respectively), soluble sugars (4.63 mg g-1 FW), lower post-harvest MDA content (0.32 µM g-1 FW), and increased duration of vase life (26 days). In general, SNP and putrescine improved rose growth parameters and post-harvest traits.

月季花瓶寿命及生化指标研究。叶面施用硝普钠和腐胺对雪崩有影响

摘要叶面喷施硝普钠(SNP)和腐胺(Put)对月季生长的影响。雪崩调查。本试验采用两因子的析因试验，分别为0、50、100和200 μM 4个水平的SNP和0、1、2和4 mM 4个浓度的腐胺，在温室水培条件下进行3个重复。记录的一些性状包括叶片数，叶面积，鲜叶和干叶重，以及可溶性糖和总蛋白的测定。此外，在收获后阶段，重新编码的性状包括丙二醛(MDA)含量、相对鲜重和花瓶寿命。与对照相比，100 μM浓度的SNP改善了叶片的鲜重和干重(分别为4.3 g和1.4 g)。在100 μM处理下，总蛋白含量增加(0.85 mg g-1 FW)，采后MDA含量降低(0.32µM g-1 FW)，花瓶寿命延长(23.66 d)，叶面积增加(7671 mm2)，花相对鲜重增加(27.65%)。在不同腐胺浓度下，4 mM腐胺处理的叶片面积(8056.7 mm2)、鲜叶重和干叶重(分别为4.3和1.3 g)、可溶性糖(4.63 mg g-1 FW)、采后MDA含量(0.32µM g-1 FW)较低，花瓶寿命(26天)较长。总体而言，SNP和腐胺改善了月季生长参数和收获后性状。
