Description
Technical field
The present invention relates to a kind ofly in plant leaf blade heliotropism motion, can be used to measure the plant leaf blade motion orientation angles measuring instrument that the blade movement angle changes.
Background technology
The blade of plant was not to remain on fixing position in one day always, and some plant leaf blade changes with the variation of solar motion orientation and angle, and this is called as the heliotropism motion.Heliotropism phenomenon in the blade movement extensively is present on each kind of plant, comprises the yearly plant and the herbaceous plant in arid and semi-arids such as velvetleaf, puncture vine area, and crops such as cotton, beans, clover, lupin.The heliotropism motion is divided into two types again: a kind of is the diaheliotropism motion, and blade movement always makes the leaf plane vertical with the incident ray of the sun, to catch more luminous energy; Another kind is inclined to one side heliotropism motion, and blade movement always makes the leaf plane parallel with the incident ray of the sun, catches to reduce luminous energy.Research thinks that the diaheliotropism motion of blade has improved the plant photosynthesis yield-power, helps occurring building up seedling and accomplishing the history of life fast before the unfavorable factors such as arid, heat stress at environment; The aspect that influences from light is intercepted and captured because plant leaf blade has been intercepted and captured luminous energy to the full extent, obtains the advantage of contention light resources simultaneously, the luminous environment around therefore can influencing, and the rival of shading to a greater extent obtains the struggle for existence advantage.The inclined to one side heliotropism motion of blade can be avoided the light inhibition of high light intensity to blade, reduces the rising dehydration of blade; Cause the inner light quantity of accepting of plant canopy to increase simultaneously, help lower blade and carry out photosensitizing substance production.This shows that this locomitivity of plant can influence the photosensitizing substance production of plant and grow, finally can influence the survival and development of these species.
Forefathers to the heliotropism of plant leaf blade motion carried out big quantity research, how to comprise that motion is measured to the blade heliotropism, i.e. blade translation-angle how is spatially just measured position angle, deflection and the suspension angle of blade.Said position angle is the angle between blade tip end and the box compass north arrow (north orientation).Place on the leaf plane with hand-held box compass, the adjustment box compass makes 0 ° of pointed, and blade tip end this moment reading of indication on compass is the position angle; Said deflection is to be axle with arteries and veins in the leaf, blade steering east or western angle.Hang a little perpendicular as reading index with semicircular protractor from diameter center (center of circle); Place arteries and veins vertical direction in semicircular protractor plane and the leaf; Make the diametral plane (semi circular surface) of semicircular protractor keep being close to the leaf plane, this moment, the reading of perpendicular was exactly a deflection; Said suspension angle is the angle on arteries and veins vertical movement leaving water plane in the leaf.With the parallel Ye Zhongmai that is close to of the diameter crossbeam of semicircular protractor, this moment, the reading of pedal line hung the angle exactly.
The measuring method of blade heliotropism motion mainly contains orientation angles determination method, sciagraphy, pinpoint photograph method etc.The determination of azimuth method is to use protractor, and pedal line and box compass are measured position angle, deflection and the suspension angle of blade, just can the locus of blade be positioned through these three angles, and then describes the motion state of blade; Sciagraphy is to utilize the projection of blade to describe the state of blade movement.Below blade, place a flat board, utilize the ratio of the real area of projected area and the blade of blade on this plane, obtain blade face normal and sunray angulation perpendicular to sunshine; The pinpoint photograph method is different with two kinds of above-mentioned mensurations, and it is variation of taking blade with fixed camera in every interval 1-2 hour, and catching visually, how blade carries out the method that heliotropism is moved.
Though more than three kinds of methods all can describe out plant leaf blade and how to carry out the heliotropism motion, every kind of method all exists relative merits separately in actual application.Though how the orientation angles determination method can spatially move to blade analyze, only be fit to the comparatively simple plant of blade movement mode, such as cotton; On measuring blade, seem unable to do what one wishes, such as beans to the more complicated plant of mode of motion.This method is bigger at the mensuration time error, and can't describe the light state that receives of blade.Sciagraphy can be described the light state that receives of blade, reflects that very directly what of light intensity blade accept, but this method can't analyze blade on dimensional orientation, can not reflect blade motion process spatially, and complicated operation in use.The pinpoint photograph method can reflect the state and the change procedure of blade heliotropism motion very intuitively, but mode of motion that can't the quantitative description blade and receive light state.
Assay method to the motion of blade heliotropism is improving continuously, but makes slow progress, the instrument that the blade heliotropism motion of also not commercially producing is specially at present measured.Therefore; On the basis of using for reference above-mentioned various assay method relative merits; Design the determining instrument that is specifically designed to the motion of plant leaf blade heliotropism, it is accurate and convenient and swift to accomplish to measure the result, and this is for carrying out and advancing plant leaf blade heliotropism motion study to have important and practical meanings.
