Influence of gibberellin treatment on flowering and fruiting patterns in mango

CGN Turnbull; KL Anderson; EC Winston Australian Journal of Experimental Agriculture 1996. doi:10.1071/ea9960603

Other claims from this paper (11)

Intervention effect Winter GA3 spray delayed mango flowering by up to four weeks in coastal subtropical Queensland.
Intervention effect Winter GA4 spray delayed mango flowering by up to four weeks in coastal subtropical Queensland.
Intervention effect GA treatments generally reduced panicle number, especially at higher concentration.
Intervention effect GA3 did not affect timing of flowering in Kensington Pride and Keitt in tropical North Queensland.
Intervention effect GA3 did not affect extent of flowering in Kensington Pride and Keitt in tropical North Queensland.
Association Fruit yield was highly correlated with the proportion of flowering terminal buds.
Intervention effect GA treatments significantly reduced yield in Kensington Pride, especially at 200 mg/L when only 23% of terminal buds flowered.
Association Fruit size was inversely related to yield.
Association Delayed flowering led to fruit maturation up to two weeks later.
Observation Late-flowering Early Gold panicles retained three times more fruit than early-flowering panicles.
Recommendation The authors recommend careful GA concentration and timing to delay flowering without reducing flowering and yield.
