Forced Flowering in Mandarin Trees Under Phytotron Conditions
2019
[EN] Phytotron has been widely used to assess the effect of numerous parameters on the development of many species. However, less information is available on how to achieve fast profuse flowering in young fruit trees with this plant growth chamber. This study aimed to outline the design and performance of a fast clear methodology to force flowering in young mandarin trees (cv. Nova and cv. Clemenules) and to analyze the influence of induction intensity on inflorescence type. The combination of a short water stress period with simulated spring conditions (day 13 h, 22 °C, night 11 h, 12 °C) in the phytotron allowed flowers to be obtained only after 68-72 days from the time the experiment beg…
Estimation of chilling and heat requirements of six sweet cherry (Prunus avium L.) cultivars
2022
Warmer winters without sufficient chilling due to climate change in Mediterranean regions represent a threat for deciduous fruit tree species such as sweet cherry (Prunus avium L.) with high chilling requirement, since it will affect fruit tree phenology leading to dramatic yield reduction and fruit industry income loss. Quantifying chilling requirements to overcome winter dormancy is crucial for identifying suitable cultivars for a given site, for predicting the necessity and timing applications of rest-breaking chemicals and the possible consequences of climate change. The aim of the following study was to determine the chilling and heat requirements of six sweet cherry cultivars grown in…
