Exempel på boll

• As the blossoms die they are replaced by the young bolls, or pods, which contain the seeds. 

• At first cotton-picking was interesting, the fluffy bolls looking like artificial roses and the stray blossoms strangely shaped and delicately pink. 

• In the autumn you see the pod or boll which contains the cotton. 

• The bolls are placed on racks, and are sun-dried, after which the husks are removed by hand. 

• The top of the cotton stalk glimmered with a purple bloom, but down between the rows, among the dying leaves, the first bolls were opening. 

• In this investigation, quantification of fibre quality in individual bolls revealed wide variations in fibre maturity.

• One must remember, however, that the green bolls were of large size and that a large proportion of them must have been approaching maturity.

• This comparison focused on the phenological cycle of cotton plants, especially the flowering stages: fruiting onset and effective flowering time (period when bolls are initiated).

• There was no significant positionrcultivar interaction, thus, mote frequencies between bolls at different plant positions were not affected by cultivars.

• Ten bolls were harvested for each plant position.

• Source-sink relations as affected by water stress during boll development.

• A further important fact is that a diet of unopened bolls leads, in general, to a high mortality with prolongation of the stadia.

• Of the three yield components (boll number, boll weight and lint percentage), boll number was the most sensitive to shade.

• Total bolls per plant were also measured immediately prior to harvest.

• High levels of late season cotton aphid infestation can cause aphid honeydew accumulation on open bolls, resulting in sticky cotton lint.

• The decrease in lint yield for shaded cotton was mainly associated with a decrease in the number of retained bolls.

• Bolls at the middle and top parts of the plant had lower mote frequencies than bolls at the bottom of the plant.

• The fruiting site of a boll represents a unique microsite with individual combinations of temperatures, light and metabolic resource allocations.

• However, the final effect of treatment on the number of bolls per plant was not significant in either year.

• Not until the fourth instar was reached did nymphs thrive satisfactorily upon unopened bolls.
