Title

Morphology of flower bud differentiation and floral organ specialization in Caucasian clover

Hui‐min Zhang; Ming‐jiu Wang; John Hampton; et al. Grass and Forage Science 2024. doi:10.1111/gfs.12658

Other claims from this paper (11)

Observation Caucasian clover flower bud differentiation has six consecutive stages.
Observation The anther has two chambers.
Observation Pollen grains have six developmental phases.
Observation The microspore tetrad is tetrahedral and mature pollen grains are bicellular.
Observation Pollen grain viability was 35%.
Observation The monocarpelate ovary contains one or two ovules covered by two layer integuments.
Observation The ovule is anatropous.
Observation Embryo sac development is polygonum type.
Observation The floral formula was reported.
Mechanism Two pollen sacs and low pollen viability may explain low natural seed setting.
Mechanism Embryo sac dysplasia and resulting ovule sterility may also explain poor seed setting.

Title

Impact of reproductive duration on yield and its component traits in lentil

Jitendra Kumar; Ekta Srivatava Legume Research - An International Journal 2015. doi:10.5958/0976-0571.2015.00077.6

Other claims from this paper (13)

Observation Reproductive duration and other agronomic traits varied significantly, except harvest index.
Observation Harvest index did not show significant variability.
Association Longer reproductive duration was associated with lower yield.
Association Long reproductive duration was associated with increased seed size.
Association Variability in reproductive duration depended on days to 50% flowering rather than days to maturity.
Association Days to 50% flowering and days to maturity had a highly significant negative correlation.
Association Biological yield per plant was positively related to grain yield.
Association Plant height had a positive impact on biological yield.
Association Pods per plant had a positive impact on biological yield.
Association Harvest index was not associated with reproductive duration.
Observation LL 864 had the maximum pods per plant, high biological yield, and high yield.
Observation IC520341 was identified for early flowering.
Recommendation The identified genotypes could be useful in breeding early maturing, high yielding lentils.

Title

The Effect of Non-Woven Fabric Floating Row Covers on the Emergence, Growth, and Bulb Yield of Direct-seeded Onions (Allium cepa L.) in a Subarctic Area

Goh Hirai The Horticulture Journal 2018. doi:10.2503/hortj.okd-172

Other claims from this paper (12)

Intervention effect Row covers raised mean daily maximum soil temperature by about 4-5C.
Intervention effect Row covers raised mean daily minimum soil temperature by about 1-3C.
Observation The effect of row covers on soil moisture varied by year.
Intervention effect Row covers advanced onion emergence by 1 to 4 days.
Intervention effect Row covers promoted early growth.
Intervention effect The growth difference between covered and uncovered onions diminished toward bulb formation and was almost nonsignificant then.
Intervention effect Row covers advanced lodging in 2015.
Intervention effect Row covers had little effect on bulb yield.
Intervention effect Row covers decreased onion survival under simultaneous heat and drought.
Intervention effect Row covers tended to reduce onion maggot feeding damage.
Mechanism The authors attributed improved emergence and early growth mainly to warmer soil under row covers.
Recommendation The authors suggested row covers to reduce emergence, growth, lodging and onion maggot damage risks.
