The essential features of the invention can be seen in the embodiments and examples described below, which should not be construed as limiting the invention in any way.
Example 1: effect of 3-methyl-2-methylaminovaleric acid on cucumber seedling rooting
In order to study the growth promoting effect of 3-methyl-2-methylamino pentanoic acid on plant root system, a model system for studying lateral root generation, namely a cucumber seedling system without radicles, was selected. Spreading four layers of wet gauze at the bottom of the culture box, selecting cucumber seeds (variety "early summer autumn crown", Shandong Ningyang county Luming seed Co., Ltd.) with full shape and uniform size, sterilizing with 75% alcohol, washing with distilled water, spreading on the gauze, and covering with four layers of wet gauze to prevent light. After 24 hours at 25 ℃ in a dark room, the germinated cucumber seeds were taken out and buried under the soil at 1 centimeter (cm). After 3 days, a plurality of seedlings with consistent growth vigor and two completely unfolded cotyledons are taken, the roots are washed clean by distilled water, radicles are cut off along hypocotyls, the plants are fixed by sponge strips and placed in a culture box. 400 mL (mL) of 3-methyl-2-mevalonic acid in water at concentrations of 0, 10, 100 and 1000nM were added to each box. The hydroponic plants are placed in a culture room at 25 ℃, and after 6 days of illumination culture, the plants are taken out to measure and record the root length, the number of lateral roots, the fresh weight of the roots and the fresh weight of the whole plants. The results are shown in Table 1.
TABLE 1 Effect of different concentrations of 3-methyl-2-methylaminopentanoic acid on cucumber seedling rooting
As shown in Table 1, 10-1000nM 3-methyl-2-methylaminopentanoic acid was found to promote rooting of cucumber seedlings. At concentrations of 10, 100 and 1000nM, cucumber root length increased by 102%, 205% and 103%, respectively, compared to the blank control; the number of lateral roots is respectively improved by 53 percent, 69 percent and 54 percent; the fresh weight of the root is respectively increased by 67 percent, 167 percent and 33 percent; the fresh weight of the whole plant is respectively increased by 39%, 54% and 22%. Among them, 100nM of 3-methyl-2-methylaminopentanoic acid treatment gave the best results. The above results indicate that 3-methyl-2-methylamino pentanoic acid can significantly promote the generation and growth of root systems of cucumber seedlings.
Example 2: effect of 3-methyl-2-methylaminovaleric acid on cucumber seedling growth
Spreading four layers of wet gauze at the bottom of the culture box, selecting cucumber seeds (variety "early summer autumn crown", Shandong Ningyang county Luming seed Co., Ltd.) with full shape and uniform size, sterilizing with 75% alcohol, washing with distilled water, spreading on the gauze, and covering with four layers of wet gauze to prevent light. Placing in a 25 deg.C incubator in dark place for 24 hr, taking out germinated cucumber seeds, burying in plastic pots (diameter 12cm) filled with wet (saturated moisture) soil, depth 2-3cm, 5 granules per pot, and placing in a 25 deg.C incubator (light intensity 200 μmol m) -2s-1) And (4) culturing. After 3 days, 1 robust seedling with fully developed cotyledons was kept, and the other 4 seedlings were removed. Then, 3-methyl-2-formazan was slowly watered in each pot at a concentration of 0 (blank control) and 100nM along the base of the seedling stemAminopentanoic acid (50 mL) was added, and the culture was continued in a 25 ℃ incubator with light. Observing and recording the plant height and true leaf growth condition of each treated cucumber seedling on 6 th and 12 th days after treatment; on day 18, the plant height, first true leaf area, second true leaf area, third true leaf area, fresh weight of the whole plant, fresh weight of the overground part, fresh weight of the underground part and root length of each treated cucumber seedling were measured. The results are shown in Table 2.
TABLE 23 Effect of methyl-2-mevalonic acid on cucumber plant seedling growth
The results in table 2 show that 3-methyl-2-methylaminovaleric acid significantly promotes cucumber seedling growth compared to the blank control. For example, on day 12, the blank control group had not yet developed a second true leaf, whereas cucumber seedlings treated with 100nM 3-methyl-2-mevalonic acid had developed a leaf area of 9.74cm2The second true leaf of (1); on day 18, the blank control group had not yet developed a third true leaf, while cucumber seedlings treated with 100nM 3-methyl-2-mevalonic acid had developed a leaf area of 4.16cm 2The third true leaf of (1). On day 18, the plant height, first true leaf area, second true leaf area, whole plant fresh weight, aerial part fresh weight, underground part fresh weight and root length of the cucumber seedlings treated with 100nM 3-methyl-2-mevalonic acid were increased by 22%, 62%, 94%, 54%, 40%, 132% and 48%, respectively, compared to the blank control. This shows that 3-methyl-2-methylamino pentanoic acid can promote the development of seedling, root, stem and leaf and fast growth obviously.
