Other claims from this paper (17)

Intervention effect D-poly houses increased tomato marketable yield by 15% to 16% over glasshouses.
Intervention effect D-poly houses increased tomato fruit number per area by 13% to 17% over glasshouses.
Intervention effect Under supplemental lighting, acrylic houses had similarly higher yield and fruit number than glasshouses.
Intervention effect Covering materials had no significant effect on tomato photosynthesis and leaf chlorophyll.
Intervention effect Supplemental lighting increased leaf number in glasshouses in March by 15%.
Intervention effect Supplemental lighting increased tomato marketable yield in acrylic houses by 23%.
Intervention effect Supplemental lighting increased leaf specific weight in all houses by 19% to 33%.
Intervention effect Supplemental lighting increased total chlorophyll in acrylic houses by 10% to 14%.
Intervention effect Supplemental lighting increased tomato photosynthetic rate in March in glasshouses by 22%.
Intervention effect Without supplemental lighting, tomato plants in acrylic houses were taller than those in glasshouses.
Intervention effect Neither greenhouse covers nor supplemental lighting affected dry matter allocation to tomato fruit.
Recommendation The authors suggest D-poly and acrylic houses with supplemental lighting for early tomato yield in southwestern Ontario.
Observation Without supplemental lighting, photosynthesis fell 18% in acrylic houses after two months.
Observation Without supplemental lighting, photosynthesis fell 15% in D-poly houses after two months.
Observation Without supplemental lighting, photosynthesis fell 15% in glasshouses after two months.
Observation Under supplemental lighting, the decline in carbon exchange was not significant in D-poly houses.
Mechanism The authors conclude that March leaf starch accumulation did not explain the observed photosynthetic decline.

Changes in Photosynthesis and Carbohydrate Reserves of ‘Fuji’/M9 Apple trees in Response to Early Defoliation at Growing Period

Jae Hoon Jeong; Jeom Hwa Han; Suhyun Ryu; et al. Protected horticulture and Plant Factory 2017. doi:10.12791/ksbec.2017.26.4.291

Other claims from this paper (9)

Intervention effect Bud regrowth was 82.7% after 80% defoliation, significantly different from the other treatments.
Intervention effect Bud regrowth was 45.9% after 50% defoliation.
Observation Bud regrowth was 2.1% without defoliation.
Observation Sucrose and starch in remaining leaves declined nonsignificantly during 14 days in all treatments.
Observation Total soluble carbohydrates did not significantly change with no defoliation or 50% defoliation.
Intervention effect Sorbitol and total soluble carbohydrates declined in remaining leaves after 80% defoliation.
Intervention effect Net photosynthetic rate and stomatal conductance were significantly enhanced at 80% defoliation.
Mechanism Authors propose enhanced leaf osmotic potential may explain photosynthetic enhancement after partial defoliation.
Mechanism Authors attribute increased photosynthesis after partial defoliation to carbohydrate requirements for bud regrowth.
