Add  Long-term ethephon stimulation 1. Effects of continuous ethephon stimulation with half-spiral alternate daily tapping.
Authors: Sivakumaran, S. | Pakianathan, S.W. | Gomez, J.B.
Date: 20030923 | 20050822 | | 1981 | | | | | | |
Subject: PRRIM
Type: Article
Identifier: vital1:24626
Description: The analysis of results from long-term ethephon treated trees shows that high peak responses to stimulation were only obtained during the first three to four stimulations on the panel, and this was ne… More

Subject: PRRIM | Exploitation: stimulation and yield
Type: Article
Identifier: vital1:24576
Description: Cumulative yields obtained on d/2 frequency of tapping were generally better than those on the low frequency systems after seven to nine years of stimulation. However in three clones, Tjir 1, RRIM 623… More
