L. Strobilus In Situ Photosynthesis and Respiration Temperature Responses.

The primary metabolism and respiration of the hop strobilus has not been quantified in response to daily temperature fluctuations. The objective of this study was to assess strobilus gas exchange, specifically the response to temperature fluctuations. Hop strobilus were measured under controlled environment conditions to assess the organ's contribution to carbon assimilation and respiration during the maturation phase.

Leaf Age and Position Effects on Quantum Yield and Photosynthetic Capacity in Hemp Crowns.

We examined the aging of leaves prior to abscission and the consequences for estimating whole-crown primary production in L. (hemp). Leaves at three vertical positions in hemp crowns were examined from initial full leaf expansion until 42 days later.
