WebJA treatment delayed flower opening as well as petal abscission by more than 24h in R. bourboniana and also increased transcription of the JA pathway genes, unlike ethylene. The strong and rapid reduction of the entire JA pathway in the AZ in R. bourboniana flowers, prior to flower opening and petal abscission, suggests a negative role for JA ...

WebMar 1, 1993 · Shade reduced pod numbers and the reductions were due to both increased flower and pod abscission and fewer flowers per plant. Both the number of nodes on the main stem and flowers per node were affected by the shade. Shade during any part of the R1 to R6 period reduced pod numbers in the greenhouse. These data indicate that …
