The Research On The Effect Of Plant Inhibitors On The Physiology And Growth Of The Commelina Benahalensis

The Tradescantia fiumiensis(Commelina benahalensis L.)has a match head,Bam boo dish round leaf Dayflower etc.Belonging to the order of the first leaf plant,Trad escantia fiumiensis,herbaceos perennial.Tradescantia fiumiensis habit strong,leaves thi ck,purple flower is lovely,summer and fall flowering,there's some resistance to it,It can be introduced domestication has become an excellent indoor ornamental plant.But in less light easy to moderate growth.Therefore,this paper studies the Tradescantia fi umiensis,sing different pygmy and different ways of handling it,The hormone and th e use of the best dwarfing effect of the white flower purple dew grass are to be scre ened.It provides a basis for their application in garden green space.Different plant gr owth inhibitors(dazole,cystotin)were used for the experimental seedling and spraying of a consistent white flowering purple dew plant.The total content of chlorophyll in each treatment group was measured regularly(Ch1),Malondialdehyde(MDA)?solub le sugar(SS)?conductivity?peroxidase(POD)?soluble protein(Sp)?chlorophyll fl uorescence parameters?The change of external morphological characteristics and other indicators.The results are as follows:(1)Effect of multieffect azole onTradescantia fiumiensis.? Water group The dwarfing effect of water multi-effect azole on white flower purple dew is obvious.as the concentration increases,The apparent degree of the dw arfing effect was increased and then decreased.The treatment group of 20mg/L was t he most obvious,Performance in shortening the interodes,The new leaf and the flowe r pavilion are the most obvious.Enhanced the photosynthesis of the white flower purp le dew,And as the concentration increases,The promotion effect of cooperation will decrease.As the processing time increases,the MDA content and conductivity of the plant increased,the cell membrane is destroyed,But with the soluble sugar in the body,the increase in soluble protein and POD content,the resistance of the plant is enhan ced.But it's not related to the concentration.Well,the generalization,Watering 20mg/L is best for dwarfing.? Spraying group The spray pattern has a low effect on morphological charact eristics.And there's not much difference between the concentrations,however,the result s of the fluorescence parameters indicate that,the spraying method significantly reduce s the photosynthesis of white flower purple dew,and as the concentration increases,the decrease becomes more obvious.As the lengthen of time,as you can see from the v arious physiological indicators of resistance,between groups of resistance does not incr ease,the concentration of 200 mg/L processing group of the strongest resistance,there fore,the wandering Jew spraying multi-effect azole optimal concentration of 200 mg/L.? By the above two results,you can see that water and spraying multi-effect az ole all have obvious effect of dwarf,but spraying multi-effect azole physiological dam age of wandering Jew,and wandering Jew is yellow powder,spraying on the leaf has a yellow stains,affect the landscape effect.Therefore,it is most appropriate to water the white flower purple dew grass with the use of multi-effect azole.(2)The effect of the short and strong element on the white tradescantia fiumiensis? Water group Watering cycocel of wandering Jew dwarf effect is obvious,wit h the increase of concentration,dwarf degree,the more obvious,can be seen from the morphological characteristics and physiological indexes,when the concentration of 50 mg/L,100 mg/L has little influence to wandering Jew,irrigate cycocel optimal conce ntration of 400 mg/L.? Spraying group Experimental results show that the spraying cycocel dwarf eff ect of wandering Jew also clear,and with the increase of the concentration of the spr aying,dwarfed the effect is more apparent,but when the concentration of 4000 mg/L,8000 mg/L per liter,plants showed obvious adr,serious influence plant landscape eff ect.and their bodies chlorophyll content decreased,harmful material increase,destructi on.of plant cells,and adjust the material increase in small,therefore,the optimal conc entration for spraying cycocel 2000 mg/L.?Watering and spraying the short and strong element can make the white flower violet grass produce the low effect.Spraying concentration is too high can bring cert ain phytotoxicity to wandering Jew,affect the landscape effect,when the concentration of 2000 mg/L,best effect,and watering cycocel dwarfed effect is best,with the incr ease of the concentration in the experiment,this paper when the concentration of 400 mg/L shape characteristic performance than spraying the effect of the concentration of 2000 mg/L,therefore,the best way to use cycocel for spraying concentration of 2000 mg/L.(3)Experiment,this paper multi-effect azole and cycocel dwarf effect of wandering Jew from the data,taken together,these results are two plants inhibitor combined wit h use the dwarfing effect after strength sorting result is as follows:multi-effect azole watering(multi-effect azole spraying(CCC spraying(CCC watering.Therefore,from t he results of this experiment,the method of the short effect is the water concentration of 20mg/L.
