In the last few years, spring frosts have become more of a rule than an exception. There are several prevention measures available for growers and numerous being tested; however, fruitlets often affected to some extent. One common phenomena is development frost rings. The aim our study was evaluate how occurrence rings affects sugar, organic acid, phenol content in flesh peel cv. ‘Gala’ apples....

Agroclimatic variables in different time windows were analyzed using Artificial Intelligence techniques to estimate the fruit growing season extension and harvest start date for ‘Gala’ apples (Malus domestica (Suckow) Borkh.) Meteorology phenology data collected from five orchards Central Chile, between 2004 2019. The attributes derived air temperature during first days of showed high relat...

The apple (Malus domestica Borkh.) is one of the major fruit tree crops, but it hasn’t been well-studied as a breeding object for molecular investigations. It important to develop reliable and rapid methods that allow preparation plant material future research. We introduce quick simple method isolating high-quality RNA from lipid-rich seeds (M. cv. Golden Delicious). Our does not employ highly...

Flower induction in apple (Malus domestica Borkh.) trees plays an important life cycle role, but young trees produce fewer and inferior quality flower buds. Therefore, shoot bending has become an important cultural practice, significantly promoting the capacity to develop more flower buds during the growing seasons. Additionally, microRNAs (miRNAs) play essential roles in plant growth, flower i...

Shi, Biying. M.S., Purdue University, May 2015. Growth Parameters for 'Golden Delicious' Apple Trees (Malus × domestica Borkh.). Major Professor: Peter Hirst. High yield and high quality of tree fruit result from appropriate orchard design and management practices. This requires an accurate knowledge of vegetative growth, branching, and flowering processes of fruit trees. Tree development knowl...
