In order to establish the profile of productivity of the lentil plant, the yield, yield components, and aborted flowers retained to maturity at every flowering node, were evaluated on Araucana-INIA, ILL-28, and Laird genotypes. The study was conducted at the Carillanca Exp. Sta. (INIA, Temuco) during the 1983/84 season. Pods/node, seeds/pod, seed weight, and yield/node were highest at the lowest nodes of the branches, becoming progressively reduced upwards. Only in Laird, the seeds/pod component was not altered throughout the branch profile. Nades 1 to 3 on primary branches and node 1 on secondary branches were the most productive, contributing with 71.2, 91.1, and 67.6% of the yield/plant in Araucana-INIA, ILL-28 and Laird, respectively. Improductive (empty) pods averaged 22% at the lowermost and 100% at the uppermost pod-bearing nodes. Aborted flowers were observed mainly in the upper section of the branches, contributing from 52 to 100% to the reduction of pods at the uppermost reproductive nades. |
