The authors judge that replacing diploid by triploid males in presently seeded hop yards will probably decrease yields slightly, offset by the premium for a seedless crop.

Title

Other claims from this paper (14)

Intervention effect Hand pollination of six diploid hop cultivars increased cone size by 7 to 24%, regardless of the ploidy of the pollen parent.
Intervention effect In 1973, pollination from diploid males increased hop cone weights by an average of 46%.
Intervention effect In 1973, pollination from triploid males increased hop cone weights by an average of 17%.
Intervention effect Bracts plus bracteoles increased by an average of 23% over the untreated control after diploid pollination.
Intervention effect Bracts plus bracteoles increased by an average of 11% after triploid pollination.
Intervention effect Pollination had the most striking effect on strig length and strig weight.
Intervention effect Pollination had little effect on the number of nodes per strig.
Intervention effect Seeds from triploid pollination averaged less than half the weight of the open-pollinated control.
Intervention effect Seeds from triploid pollination contained 60 to 83% aborted embryos.
Intervention effect Seeds from diploid pollination contained only 18% aborted embryos.
Observation Well-filled seeds were purple and usually weighed three to four times as much as tan seeds.
Intervention effect Seeds from triploid pollination had about 25% less crude fat than seeds of the control.
Observation Cones from triploid pollination look like seeded cones but contain only about one-fourth as many seeds as those pollinated by comparable diploid males.
Recommendation The authors judge that hop yields in seedless production areas probably can be increased significantly by using pollen from triploid males to stimulate cone size and weight.

DECREASING SHOOT LENGTH IN 'FUJI SUPREMA' APPLE TREES WITH TRINEXAPAC-ETHYL IN SOUTHERN BRAZIL

G. de A. Meyer; M.E. Bueno; A.R. Luz; et al. Acta Horticulturae 2014. doi:10.17660/actahortic.2014.1042.38

Other claims from this paper (12)

Intervention effect Tri-E reduced shoot length more than 50% in 2011/2012.
Intervention effect Pro-Ca reduced shoot length more than 50% in 2011/2012.
Intervention effect PBZ reduced shoot length 36% relative to control.
Intervention effect Almost all Tri-E doses reduced shoot length about 20% in 2012/2013.
Intervention effect Pro-Ca reduced shoot length about 20% in 2012/2013.
Intervention effect No yield differences were observed among treatments and control.
Intervention effect Tri-E reduced productivity relative to control in 2012/2013.
Intervention effect Tri-E at 200, 250 and 400 mg/L increased fruit set more than 60% over control.
Intervention effect Tri-E at 200 and 250 mg/L reduced vegetative growth of Fuji Suprema.
Intervention effect Tri-E at 200 and 250 mg/L produced firmer fruit.
Intervention effect Tri-E at 200 and 250 mg/L raised soluble solids.
Intervention effect Tri-E at 200 and 250 mg/L had no residual effect on post harvest fruit quality.

Crop Coefficient-based Deficit Irrigation and Planting Density for Onion: Growth, Yield, and Bulb Quality

Daniel I. Leskovar; Shinsuke Agehara; Kilsun Yoo; et al. HortScience 2012. doi:10.21273/hortsci.47.1.31

Other claims from this paper (10)

Intervention effect Planting density did not significantly affect leaf fresh weight.
Intervention effect Deficit irrigation at 50% ETc reduced leaf fresh weight.
Intervention effect Higher planting density reduced average bulb size by 12%.
Intervention effect Higher planting density increased marketable bulb number by 21% to 33%.
Intervention effect Higher planting density increased marketable yield by 7% to 14%.
Intervention effect Deficit irrigation tended to reduce bulb number and bulb size.
Intervention effect At 75% ETc, yield fell by 8% to 13%.
Intervention effect At 50% ETc, yield fell by 19% to 27%.
Intervention effect Planting density and deficit irrigation had no significant effect on soluble solids, pungency or quercetin.
Recommendation Growers could adjust planting densities to target high-value bulb sizes.
