Title

Use of Triploid Males for Increasing Hop Yields¹

Alfred Haunold Crop Science 1975. doi:10.2135/cropsci1975.0011183x001500060026x

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.

SOIL MOISTURE AND ROOT DISTRIBUTION IN AN APPLE ORCHARD IRRIGATED BY TRICKLERS

I. Levin; R. Assaf; B. Bravdo Acta Horticulturae 1979. doi:10.17660/actahortic.1979.89.12

Other claims from this paper (5)

Intervention effect Twice-weekly irrigation with 8 1/h tricklers gave a wider soil moisture distribution than daily or weekly irrigation with 4 1/h tricklers.
Intervention effect Twice-weekly irrigation with 8 1/h tricklers gave a wider root distribution than daily or weekly irrigation with 4 1/h tricklers.
Intervention effect Daily irrigation gave a narrower soil moisture distribution than weekly irrigation.
Intervention effect Daily and weekly irrigation gave similar root distribution patterns.
Observation Saturation under the trickler led to drainage loss estimated at 17% of applied water while irrigation continued.

Analysis of Yield-Determining Process and Its Application to Yield Prediction and Culture Improvement of Lowland Rice : XCIII. Effects of different temperature conditions and fertilizing conditions dufing a nursery period on the growth and characteristics of rice seedlings

Takafumi HOSHINO; Seizo MATSUSHIMA; Toyoo TOMITA Japanese Journal of Crop Science 1971. doi:10.1626/jcs.40.197

Other claims from this paper (10)

Association Higher water temperature advanced rice seedling leaf age.
Association Fertilizing conditions, including nitrogen amount, also influenced rice seedling age.
Intervention effect At low air and water temperatures, greater nitrogen amount and concentration increased seedling height and dry matter measures.
Intervention effect At high temperatures, large nitrogen amounts adversely affected seedling growth.
Association Seedling nitrogen content tracked nitrogen fertilizer amount and responded more to fertilization than temperature.
Association Seedling carbohydrate content was high at both extreme temperatures.
Association Seedling carbohydrate content was low with water temperature of 26°C.
Intervention effect Carbohydrate content declined with increasing nitrogen except at 36°C water temperature.
Association The seedling carbohydrate to nitrogen ratio was more influenced by fertilization than temperature.
Intervention effect The seedling C/N ratio decreased progressively as nitrogen application rose at any temperature.
