CRECIMIENTO DE FRUTOS Y RAMAS DE MANZANO ‘ANNA’ (Malus domestica

Abstract

<span style="font-size: small; font-family: TimesNewRomanPSMT;"><span style="font-size: small; font-family: TimesNewRomanPSMT;"><p align="left">Growth curves of fruits and shoots in relation to time after</p><p align="left">full bloom of “Anna” apple trees growth at 2470 m altitude</p><p align="left">were determined in Paipa (Colombia). The evaluated</p><p align="left">parameters in fruits every four days were: fresh weight,</p><p align="left">dry weight, length /diameter ratio of fruits. Shoot growth</p><p align="left">was meassured at the same periodicity that by fruits. The</p><p align="left">regression ecuations for evaluated parameters are reported</p><p align="left">in this paper. The fresh weight increase of fruits was</p><p align="left">slow until 46 days after full bloom (dafb), then it was</p><p align="left">quickly until 62 dafb; among 62 and 74 dafb appeared a</p><p align="left">slow growth phase again; and finally, the growth intensity</p><p align="left">increased until the ripening time. The dry weight increase</p><p align="left">of fruits was slow until 58 dafb; and then it was quickly</p><p align="left">until 94 dafb und finally decresased from 94 dafb. The</p><p align="left">length /diameter ratio decreased until 90 dafb and then it</p><p align="left">stabilished. Shoots grew quickly until 70 dafb, and then</p><p align="left">their growth intensity decreased among 70 and 94 dafb;</p><p align="left">and finally, their growth delayed from 94 dafb. With this</p><p align="left">information it is possible to make a more rationale plan for</p><p align="left">some culture activities at this apple variety cultured in the</p><p align="left">Colombian highlands, that present similar agroecological</p><p>conditions to those in which this study was done.</p></span></span>
