AI Technical Summary

Benefits of technology

This new method uses high-energy particle irradiation (HPI) that increases photosynthesis rates while reducing damage from excessive moisture on leaves caused by low temperatures during rain or snowy weather conditions. It also prevents deteriorating root systems due to poor soil quality and improves pest control measures for crops such as citrus fruits. Overall this innovative technique helps plants grow better at higher levels without being affected even when they are exposed to harsh environmental factors like heat waves.

Problems solved by technology

The present study discusses how water deficiency affects crops during their growth process. This results in decreased productivity caused by increased evaporation rates and nutrients loss. To address these issues, various strategies like irrigating with nitrogen fertilizers were developed, reducing alkaline phytolysis and increasing osmotic pressure without damaging root systems. These measures aimed at prevention against saltwater shock stresses and promoting cellular respiration. Additionally, it suggests modifying specific metabolism paths within cells called transporters to enhance drought tolerancy. Overall, the goal of studying vegetable drought defense mechanisms involves understanding factors related to changes in biology and behavior under extreme weather conditions.

Embodiment 1

[0018] Embodiment 1, natural drought treatment evaluates the effect of radiation mutation breeding on improving the drought resistance of apple

[0019] All materials were transplanted and cultured in plastic pots (basin diameter (Φ=38cm) × basin bottom diameter (Φ=23cm)×pot height (35cm)), placed in a greenhouse, and all materials were normally watered before the test began. First, 12 apple seedlings with good growth and consistent growth were selected for each strain; the next day, all the plants were watered thoroughly and began to dry naturally. The net photosynthetic rate of the plants was measured when the soil water content was 80%, 50%, and 20% of the maximum water holding capacity in the field, and the plant phenotype was observed. When the soil water content was 20% of the maximum water holding capacity in the field, the water content, relative membrane permeability, chlorophyll content and Fv / Fm of the plant leaves were measured.

Embodiment 2

[0022] Embodiment 2, long-term drought treatment evaluates the effect of radiation mutation breeding on improving the drought resistance of apples

[0023] Two lines that were more resistant to short-term drought were selected for long-term drought stress treatment. All materials were transplanted into plastic pots (basin diameter (Φ38cm) × basin bottom diameter (Φ23cm) × basin height (35cm)) and placed in a greenhouse. All materials were normally watered before the test. For each line, 80 apple seedlings with good growth and consistent growth were selected for treatment. Two kinds of water treatments were designed in the experiment: normal watering to maintain the maximum field water holding capacity of 75% to 85% of the pot soil; moderate drought treatment to maintain the maximum field water holding capacity of 45% to 55% of the pot soil, 40 plants for each treatment . Calculate the soil water content by weighing method and record the daily water loss, and replenish the lo...

Abstract

The invention discloses a method for improving the drought resistance of apples. <12>C<6+> ions with energy of 80Me V/u and LET of 33KeVmum<-1> are used for heavy carbon ion irradiation under an ion accelerator TR4 terminal in a modern physics research institution of Chinese Academy of Sciences, dosage rate is 50Gy/min, and dosage is 0.50Gy and 60Gy. By the aid of a heavy carbon ion irradiation induced mutation technology, the net photosynthetic rate of the apples under drought, the relative water content of leaves and biomasses can be remarkably increased, chlorophyll degradation is inhibited, and the steady state of cells under drought is maintained, so that the drought stress resistance of the apples is enhanced.
