example

Potato seeds were stained with various concentrations of BF-51 containing solutions of the water-soluble concentrate described in Example 3, and after 8 days, the tubers were used. The untreated control tubers were seeded at the same time or one month earlier (early sowing). Then, the yield amount was evaluated. The results are given in Table IV.

From the results it can be stated that the controls treated with BF-51 can be seeded one week later without leaving these later sown plants in their development. This is especially important in areas where earlier sowing can be endangered by adverse, chilly spring weather. .

Example 13

10 vines of 10 buds each were soaked in a water-soluble WSC concentrate containing 10, 100 or 500 ppm of BF-51 for 24 hours, then grown under greenhouse conditions in plastic pots on a humus sandy soil.

After three months of breeding, the length of the sprouts developing on the blind vines and the weight of the sprouts and the root were determined after separation from the vines. The data were averaged for each treatment and the development of the sprouts and root was compared to the control. The results are given in Table V.

The sprout development of the grapevine was accelerated by a concentration of 10 and 100 ppm of the BF-51 90 WSC. Root development was accelerated by a concentration of 10, 100 and 500 ppm of the same WSC.

Example 14

Equal amounts of perlite impregnated with a Hvagiand nutrient solution were placed in 4 plastic culture pots of 214 cm ² opening area each. Various doses of the BF-51-50 G granules described in Example 7 were uniformly scattered on the surface of the perlite, and 10 cereal grains were sown in each pot. After the onset of soak, the course of soak for each treatment was evaluated on an ongoing basis until the percentages of onset of control reached 90% (Table VI). Furthermore, the germination, the shoot length, the green weight and the root amount in the four-leaved phase of the control plants were scored. The results are given in Table VII.

From the results it can be seen that "

a) the course of the plants' absorption has been accelerated by the treatments; and

b) both the plant height and the green weight of the plants were significantly increased compared to the control.

Example 15

After sowing (post-emergent) maize seeded in breeding pots (5 plants / pot) was sprayed with a BF-51 or gibberellic acid or 3-indolylacetic acid solution of 250 or 500 ppm concentration. In the four-leaf phase of the untreated control plants, the plant length, the green weight and the root quantity were measured (Table VIII), and the chlorophyll was determined in the top of the second leaf of each plant (Table IX).

The total chlorophyll content of the whole green weight = Ch (a + b) χ Average value of the green weight of a plant From the results it can be seen that all three active ingredients significantly accelerate the development of the plants compared to the untreated control.

The quotient of plant height and green weight, however, indicates that BF-51 exerts a more favorable effect than the comparison substances. It follows that the habit of maize is not adversely affected by BF-51, while when working with gibberelic acid disproportionately haggard plants develop with an unfavorable habit.

The values of the chlorophyll determinations indicate that BF-51 has the most favorable effect on the amount of chlorophyll formed in 1 g or in the whole green plant.

Example 16.

The root zone of tomato seedlings was watered after planting with 0.1 liter of BF-51 90 WSC solution with a concentration of 250 ppm. The development was evaluated after 6 weeks. The results are given in Table X.

Start of storage: 15.10.1984

The results of the measurements indicate that the maturation processes of the BF-51-treated apple are slowed down, thereby allowing a later-picked apple to enter the store in an optimal reading or storage ripening phase, which is a precondition for a cheap shelf life is.

The data in Table XII show that the shelf life of a BF-51-treated apple is favorable despite late harvesting and storage.
