Specific implementation mode
The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention..
Embodiment 1
Petunia kind " stress ", angle violet kind " picayune " are chosen, each kind takes 400 seeds, is seeded in 200 caves
In hole tray, after germination, chooses 270 plants of more consistent seedlings of growth and be further processed and observe.
Experimental program
Duration of experiment is 4w, is divided into 3 processing, each handles 3 repetitions, each repeats 30 samples.Specifically
Processing and curing condition such as the following table 1.
1 experiment process scheme of table
Light filling processing carries out in growth cabinet, and fluorescent lamp is unique light source, and intensity of illumination mean value is 90.71 μ
mol/m2S (converts as 6712.54lux), and true leaf number, cauline leaf dry weight, the root system of each sample are measured after illumination experiment
Dry weight and root/shoot ratio, and carry out data analysis.
1) petunia
The results show that the relatively control (CK) of the true leaf number of two processing groups of petunia (S1 and S2) does not occur significant difference (figure
1)。
In terms of dry weight, 3 groups of data cases are as follows：CK is no matter on gross dry weight, cauline leaf dry weight or weight of root system
Minimum, S1 highests, S2 are placed in the middle in 3 groups of samples.This shows that the increase with photosynthetically active radiation, the dry matter of petunia seedling are total
Accumulation obtains effective enhancing, but excessive light radiation cumulant plays reaction (S1 total dry solids weights increase compared with CK
30.0%, S2 increases only 20.2%, Fig. 2A).When dry matter is divided into above and below ground two parts analysis, the cauline leaf dry weight of S1
24.8% is increased, and S2 increases only 19.7% (Fig. 2 B)；The root system dry matter weight of S1 is even more to increase considerably, and is reached
51.2%, S2 increase only 24.4% (Fig. 2 C).With the apparent weightening of root system, rising also occurs in root/shoot ratio：CK=
0.271；S1=0.327, increasing degree 20.7%；S2=0.280, increasing degree 3.3% show that the development degree of root system is promoted, especially
It is S1.
By significance difference analysis, the gross dry weight and cauline leaf dry weight of S1, S2 have reached super significance difference compared with CK
Different (P=0.001), but then without significant difference between S1 and S2；The most strikingly, S1 weight of root system is three experimental groups
In it is highest, with CK be in super significant difference, S2 instead be less than S1, with CK be in pole significant difference, and between S1 and S2 also occur
Significant difference.
This is one group very special as a result, showing for petunia, and photosynthetically active radiation is accumulative to a certain extent
When, that is, start to generate inhibition to its nutrient growth, therefore it is to improve its production efficiency to select light filling time and intensity appropriate
It is crucial.For this research, the last 1w before being out of the garden carries out the light filling of 4h/d, can significantly promote the nutrition life of petunia
Long rate, to achieve the purpose that be out of the garden in advance or reach better quality in the identical time that is out of the garden；Meanwhile this light filling system pair
The root growth of petunia constitutes superpower facilitation, thus there may be lasting promotion works to finished product production after being out of the garden
With generating breakthrough influence to seedling quality.
2) angle violet
The results show that the relatively control (CK) of the true leaf number of two processing groups of angle violet (S1 and S2) does not occur significant difference equally
(Fig. 3).
In terms of gross dry weight, the S1 of angle violet has 6.3% promotion, S2 to only have 1.9% (Fig. 4 A) compared with CK；In cauline leaf dry weight
In, S1 increases 12.5%, and S2 increases only 6.8% (Fig. 4 B)；And in weight of root system, S1 is but considerably reduced compared with CK
10.9%, S2 similarly reduce 10.9% (Fig. 4 C).These are reacted on root/shoot ratio, cause and decline to a great extent：CK=
0.364；S1=0.287, the range of decrease 21.2%；S2=0.302, the range of decrease 17.0%.This group statistics indicate that, light filling can make angle violet
Aerial part generates some distant growths, can but reduce the development degree of root system.
By significance difference analysis, without significant difference (Fig. 4 A) between the gross dry weight of 3 groups of materials；In cauline leaf dry weight, S1
Super significant difference is formd between CK, is in significant difference (Fig. 4 B) between S2 and CK；And the weight of root system of S1 and S2 is compared with CK,
Fall has also reached the level (Fig. 4 C) of pole significant difference.
The result shows that the nutrient growth of the diagonal violet of light filling not only has no to help, or even also root system is built up to cause and is extremely shown
Write horizontal negative effect.Therefore, for this research, for this crop of angle violet, light filling promotes it nutrient growth rate
Have no to help.
