Spurred anoda (Anoda cristata) interference in wide row and ultra narrow row cotton

William T. Molin; Debbie Boykin; Josie A. Hugie; et al. Weed Science 2006. doi:10.1614/ws-05-072r1.1

Other claims from this paper (15)

Association Spurred anoda density and dry weight per plot were linearly related each year.
Observation At 8 m −2, spurred anoda dry weight was 507 g m −2 in 2000.
Observation At 8 m −2, spurred anoda dry weight was 322 g m −2 in 2001.
Observation At 8 m −2, spurred anoda dry weight was 777 g m −2 in 2002.
Intervention effect Spurred anoda did not interfere with seed cotton yield in 2001.
Intervention effect Yield losses exceeded 55% at spurred anoda density of 8 m −2 in both row spacings relative to controls.
Association The effect of spurred anoda density on cotton boll numbers was nearly identical in 2000 and 2002 across cultivar and row spacing.
Intervention effect Boll weights decreased with spurred anoda interference.
Intervention effect Spurred anoda interference decreased cotton branch dry weight in wide rows.
Mechanism In wide rows, yield decrease under spurred anoda interference was attributed to reduced boll retention or fruiting sites.
Mechanism In ultra narrow rows, yield decrease under spurred anoda interference was attributed to plant mortality.
Association Cotton plant density decreased by one plant for each additional spurred anoda in ultra narrow rows.
Intervention effect Yield per surviving cotton plant remained constant under spurred anoda interference in ultra narrow rows.
Intervention effect Neither row spacing conferred significant advantage in response to spurred anoda interference.
Recommendation Decreased boll weight and lack of compensatory boll number increase in ultra narrow rows may limit producer appeal.

Lidong Lin; Jianyong Wu Biotechnology and Bioengineering 2002. doi:10.1002/bit.10180

Other claims from this paper (9)

Intervention effect Low-power ultrasound exposure significantly stimulated shikonin biosynthesis in Lithospermum erythrorhizon cells.
Intervention effect Ultrasound at certain doses increased the volumetric shikonin yield by about 60%-70%.
Intervention effect Ultrasound exposure increased the shikonin excreted from the cells from 20% to 65%-70%.
Intervention effect Combined ultrasound with in situ solvent extraction or two-phase culture increased the volumetric shikonin yield more than two- to threefold.
Intervention effect Increasing the number of ultrasound exposures usually had negative effects on shikonin yield.
Intervention effect Increasing the number of ultrasound exposures slightly stimulated shikonin excretion.
Intervention effect Ultrasound stimulated phenylalanine ammonia lyase and p-hydroxybenzoic acid geranyltransferase.
Mechanism The ultrasound stimulation of secondary metabolite biosynthesis is attributed to defense responses of the cells to mechanical stress.
Mechanism Ultrasound-induced increase in cell membrane permeability partly explains the increased shikonin excretion.
