Embodiment 1

[0015] Example 1 Effects of antistaling agents on the opening time of single flowers of German Iris 'Black Knight' and 'Gemengd' and the vase life of flower branches

[0016] Select 'Black Knight', 'Gemengd' and strong flower branches with all the dew color of the top flowers, the length and thickness of the flower stems are relatively uniform, and contain 3 flower buds. The flower branches are about 40cm long, and the base is obliquely cut and inserted in the container. In a vase with 200 mL of preservative solution, the mouth of the bottle is sealed with plastic wrap, and the preservative solution is changed once a day. Taking iris as a control, iris belongs to the perennial iris beardless. Keep the indoor temperature at 20-25°C, relative humidity at 60-80%, light time at 14-16h / d, and light intensity at 800-1200 lx. The dehydration, wilting and curling of the iris's vertical petals are used as the symbol of the end of single flower opening, and the end of the last flower o...

Embodiment 2

[0024] Example 2 The effect of preservatives on the growth and flowering of German iris 'party dress' flower buds

[0025] Select a 'party dress' robust flower branch with all the top flowers, the length and thickness of the flower stem is relatively uniform, and contains 3 flower buds. The flower branch is about 40cm long, cut the base obliquely, and insert it into a container filled with 200 mL of preservative solution. In the vase, the mouth of the bottle is sealed with plastic wrap, and the fresh-keeping solution is changed once a day. Take calamus as a control. Keep the indoor temperature at 20-25°C, relative humidity at 60-80%, light time at 14-16 h / d, and light intensity at 800-1200 lx. The flower buds are recorded as the first, second and third flower buds from top to bottom, and the length change from the date of vase insertion to the flower bud blooming (or withering) is measured, and the ratio of the difference in the length change of flower buds to the initial len...

Embodiment 3

[0031] Example 3 The effect of preservatives on the fading of German iris 'Queen', 'Party dress' petals

[0032] Select 'Queen' and 'Party dress' strong flower branches with all the dew color of the top flowers, the length and thickness of the flower stems are relatively uniform, and contain 4 flower buds. The flower branches are about 40cm long, and the base is obliquely cut, and inserted in a container of 200 cm. mL of preservative solution, the mouth of the bottle is sealed with plastic wrap, and the preservative solution is changed once a day. Keep the indoor temperature at 20-25°C, relative humidity at 60-80%, light time at 14-16 h / d, and light intensity at 800-1200 lx. Take calamus as a comparison. Since the flower color is mainly determined by the anthocyanin content in the petals, according to the determination method of the anthocyanin content, randomly remove the pendant petals of the fully open flowers and cut them into pieces, then take 0.2g, grind and soak them w...

Abstract

The invention discloses a German iris cut-flower preservative with sodium nitroprusside as a major constituent. The German iris cut-flower preservative is prepared by dissolving and mixing the sodium nitroprusside, 8-hydroxyquinoline, citric acid and cane sugar with water, wherein the concentration of each constituent in the German iris cut-flower preservative is as follows: 80-120mu mol / L (0.02384-0.03576g) the sodium nitroprusside, 250-350mg / L 8-hydroxyquinoline, 150-250mg / L citric acid and 30-70g / L cane sugar. The preservative disclosed by the invention can obviously prolong the blossoming time of a single German iris cut-flower and the entire vase life of a flowering branch, promote the growth and blossom of a flower bud and prevent the color fading of petals.

Description

technical field [0001] The invention belongs to the technical field of cut flower preservation, and in particular relates to a German iris fresh cut flower preservative with sodium nitroprusside as the main component. Background technique [0002] German irises are mainly Iris rufica ( I. variegata ) and vetiver iris ( I. pallida ) hybrids, is a nearly sterile hybrid population. German iris is a famous perennial flower in the world. It is rich in varieties and special in color, including blue, purple, deep red (near black), yellow, multi-color, etc. Generally, there are 3-5 flowers on a scape. The opening time of a single flower in open field cultivation is 3-4 days. Many German iris varieties are widely used in North America, Western Europe and other countries as high-grade cut flowers. In my country, research on post-harvest preservation of cut iris germania has not been reported. Therefore, it is very important to study the aging physiology of cut iris germanium and ...
