Description
Technical Field
The invention relates to the technical field of agricultural cultivation, in particular to a method for increasing the spike of pepper by exogenous gibberellin.
Background
Pepper (pepper nigrum L.) is a perennial woody vine plant of the family piperiaceae (pepper) genus Piper (pepper), and has the reputation of "king of spices", not only being one of the most important spicy crops in the world, but also playing an important role in medicinal and industrial value. At present, Hainan has become the main base for pepper production in China, methods for improving the yield of pepper are continuously researched, and the number of spica is a key factor for influencing the yield. The pepper flower buds are mixed buds, vegetative growth and reproductive growth are carried out simultaneously, multiple flowering can be carried out in one year, the main flowering phase is 9-11 months per year, and the correlation between the pepper fruit ear number and the yield is the largest in the research on the pepper flowering phase regulation and the influence of pepper fruit characters on the yield, so that the flowering quantity of the pepper in the main flowering phase is a key factor influencing the yield.
The conventional flower regulating and yield increasing measure in the current production is fertilization, proper nitrogen application can promote the development of pepper spica, and excessive fertilizer input causes environmental pollution: the fertilizing amount of the pepper in 8-11 months in the rainy season of Hainan is 70% of the fertilizing amount of the pepper all year round, the centralized excessive fertilizing causes environmental pollution, and the continuous cropping obstacle of the perennial pepper is also aggravated, so that the yield of the pepper is reduced, and the economic life is shortened. Excessive fertilization is also contrary to the great demand of the new era in China, and green development of agriculture is realized. Therefore, a new method for regulating flowering and spike increment of pepper is urgently needed to realize quality improvement and synergy in pepper cultivation management.
The mechanism of gibberellin regulation of flower formation is different between model plants and perennial woody plants, for example, in Arabidopsis studies gibberellin was found to promote the transition from vegetative to reproductive growth of plants, but in mango and apple gibberellin inhibits flower bud differentiation. The gibberellin signal is enhanced to promote the plants to bloom in advance, but the gibberellin level is too high to inhibit the plants from flowering. In short day plants, the gibberellin pathway plays an important role and becomes essential because of the lack of regulation of the photoperiod flowering pathway. At present, no report on regulating the number of pepper ears by adopting exogenous gibberellin is found.

The invention adopts a conventional management method to fertilize, prune and shape the pepper, and compares the influences of a plurality of treatments on the number of pepper spica, the leaf morphological change and the photosynthetic capacity. The results of the study are as follows:
1.1 Effect of exogenous gibberellins of different concentrations on the number of spikes of pepper at different growth stages
The gibberellin spraying has obvious influence on the number of the flower spikes of the pepper in different growth stages. From the research on the influence of gibberellin on the number of the newly-extracted spica, the fact that the amount of the newly-extracted spica of pepper is increased by spraying the gibberellin can be found, along with the increase of the concentration of the gibberellin (20mg/L, 40mg/L, 60mg/L and 100mg/L), the number of the spica is increased by 1.7, 2.7, 3.7 and 5.5 times respectively, wherein the number of the newly-extracted spica is obviously increased under the treatment of the concentration of 100mg/L (figure 1A); in studies of the effect of gibberellin on the number of 2cm ears, it was found that as gibberellin concentration increased, the number of ears appeared to increase first and then decrease, with significant increases in ear number under T3-T5 treatment, with the greatest number of ears treated with T4, increasing by 4.9-fold relative to control (fig. 1B); for the ears at the development stage of 5cm, the number of the ears also shows a trend of increasing first and then decreasing along with the increase of the concentration of gibberellin, and under the treatment of T4, the number of the ears is the largest, and is increased by 86% compared with the control (FIG. 1C); in a study of the effect of gibberellin spray on the number of 8cm spikes, it was found that T4 treatment significantly increased the number of spikes by 2.4-fold relative to the control (fig. 1D). In conclusion, the effect of promoting the number of the panicles is the greatest when the gibberellin concentration is 60mg/L, and the gibberellin concentration is treated twice at 40 mg/L.
1.2 influence of exogenous gibberellins with different concentrations on leaf morphology of pepper spica in different stages of development
1.2.1 Effect on the form of the corresponding Pepper leaf of 2cm panicle
As can be seen from Table 1, pepper leaf length increased by 10%, 18%, 19%, 8% with increasing gibberellin concentration, respectively, as compared to the control, where T3 and T4 treatments differed from the control by significant levels; leaf width increases by 11%, 13%, 31%, 5%, with T4 treatment differing from controls by a significant level; the leaf area is increased by 20%, 31%, 58% and 11%, and the difference between the T4 treatment and the control reaches a significant level; leaf thickness increased by 10% and 14% over the control, respectively, for the T3 and T4 treatments, but the differences were not significant. Therefore, the effect of promoting the leaf length, leaf width and leaf area of the pepper leaves by spraying the gibberellin with the concentration of 60mg/L is the best, and the gibberellin with the concentration of 40mg/L is treated twice.

Note: the different lower case letters after each column indicate significant differences between treatments (P <0.05), the values being the average of the different treatments, the same below.
1.2.2 Effect on the form of the leaf of the corresponding Pepper source of the 5cm spica
As shown in table 2, leaf length of pepper leaves corresponding to 5cm spica increases by 13%, 24% and 11% respectively under T2-T4 treatment compared with control, wherein T3 treatment is different from control by a significant level; under the treatment of T2-T4, the width of pepper leaves is respectively and obviously increased by 19 percent, 24 percent and 26 percent; the leaf areas were significantly increased by 43%, 67%, 41% under the treatment of T2-T4, respectively. Compared with the control, the high-concentration T5 treatment reduces the leaf length, leaf width and leaf area of the pepper-source leaves by 6%, 8% and 4% respectively, but the difference is not significant. Therefore, the effect of promoting the leaf length, the leaf width and the leaf area of the corresponding pepper source leaves of the 5cm spica is best by spraying 40mg/L gibberellin, and the effect is the second time of 60mg/L treatment.
TABLE 2 Effect of gibberellins of different exogenous concentrations on the morphology of pepper-derived leaves corresponding to 5cm spica
| Treatment of | Leaf length (mm) | Leaf width (mm) | Leaf area (mm)2) | Leaf thickness (mm) |
| T1 | 102.45bc | 44.26b | 2759.95b | 0.53a |
| T2 | 115.28ab | 52.84a | 4001.51a | 0.50a |

| T5 | 96.43c | 40.74b | 2672.77b | 0.51a |
1.2.3 Effect on the form of the corresponding Pepper leaf of 8cm panicle
The influence of exogenous gibberellin on the form of the corresponding pepper source leaves of the 8cm spica is researched, and the results show that compared with a control, the leaf length, the leaf width and the leaf area of the corresponding reverse two leaves of the 8cm spica are increased under the treatment of T2-T4, but the leaf length, the leaf width and the leaf area are not obvious, and the three indexes are reduced by the treatment of T5, but the leaf length, the leaf width and the leaf area are not obvious; there was no significant difference in leaf thickness between treatments. In general, the 60mg/L treatment was most effective in promoting the morphological index of pepper leaves (Table 3).
TABLE 3 influence of gibberellins of different exogenous concentrations on the morphology of pepper-derived leaves corresponding to 8cm spica
1.3 Effect of exogenous gibberellins of different concentrations on photosynthesis of pepper leaves
The influence of exogenous gibberellin on the photosynthetic capacity of the pepper-derived leaves is researched, and the result shows that the treatment with different concentrations has no significant influence on the photosynthetic rate (Pn), the stomatal conductance (Cond) and the intercellular carbon dioxide concentration (Ci) of the pepper-derived leaves at the period; compared with the control, the transpiration rate (Tr) of the period under the treatment of T2-T4 is obviously increased by 5-38%, so that the spraying of gibberellin can promote the absorption and transportation of soil nutrients by pepper. (FIG. 2).
1.4 Effect of exogenous gibberellins of different concentrations on SPAD value of pepper leaves
The chlorophyll content of the leaves is closely related to the photosynthetic capacity of plants, and generally, the chlorophyll content is increased, and the photosynthetic capacity is enhanced along with the increase. As can be seen from FIG. 3, spraying gibberellin 60mg/L can increase the chlorophyll content of pepper leaves relative to the control, which is also a possible reason for increasing the number of pepper spikes.
Compared with the fresh water treatment, the method has the advantages that the number of the spica is increased by spraying exogenous gibberellin with a certain concentration on the premise of not influencing the growth vigor of the pepper, the number of the newly-extracted spica is increased by 1.7-5.5 times along with the increase of the concentration of the gibberellin, the number of the spica of 2cm and 5cm is increased along with the increase of the gibberellin, the increase of the treatment of 20mg/L is not obvious, and the treatment effect of the exogenous gibberellin is most obvious in the range of 40-60 mg/L.
The invention takes the young pepper as a test material, researches the influence of exogenous gibberellin on the completely developed leaf shape index, photosynthesis, chlorophyll content and the number of spica of the main flowering phase of the pepper by adopting a field gibberellin spraying technology, researches the influence of exogenous gibberellin on the number of the spica of the pepper by regulating and controlling the leaf shape and the photosynthesis physiology, and results show that the spraying of gibberellin has a remarkable improvement effect on the leaf shape index, which is a key regulating and controlling factor for promoting the increase of the number of the spica of the pepper, wherein, the spraying of gibberellin of 40-60mg/L obviously increases the leaf area and leaf thickness of pepper source leaves corresponding to the spica of 2cm, 5cm and 8cm, the total amount of the photosynthetic products is effectively increased, and in addition, the leaf transpiration and the chlorophyll value improvement under the gibberellin treatment condition also have promotion effects on the photosynthetic capacity, and the leaf transpiration and the chlorophyll value improvement are all regulating and controlling factors for increasing the number of pepper spikes. Therefore, the research on the exogenous gibberellin regulation and control of the source leaf morphology and the photosynthetic physiology provides practical theoretical guidance for increasing the spike number, improving the pepper yield and promoting the green development of the industry by adopting proper technical measures in the production.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
