SUMMARYBlack polyethylene tunnels were used to subject Armore and Missionary strawberry cultivars to 21 short-day inductive cycles at either full bloom (7–28 May) or fruit swelling (1–21 June) stages. Regardless of application date, treatments induced a second bloom 8–10 weeks after treatment in both cultivars. The second crop of Armore was as large as the first, but Missionary produced only a small second crop that would not be worth commercial harvesting. Covering plants with black polyethylene reduced the vitamin C content of the first-crop fruits of Armore without affecting yield, while Missionary responded in an opposite way. Treating plants at full bloom hastened the ripening of the first crop of both cultivars by about 1 week and resulted in a larger second crop than was obtained by the later treatment.

Two consecutive experiments demonstrated that Rieger elatior begonia cultivars Schwabenland Red and Aphrodite Cherry Red flowered earlier and most abundantly when they were grown under long days (16 h) at the early part of their growing season, followed by 3 wk of short day conditions (10 h). The plants were in full bloom within 6 wk from the time the short-day treatment began.

Public and private institutions in Spain are increasing strawberry (Fragaria ×ananassa Duch.) breeding efforts to obtain new strawberry cultivars well-adapted to growing conditions in Huelva and other Spanish areas, such as Valencia on the eastern Spanish coast. The new `Medina' is a short-day cultivar that is remarkable for its high production of first quality fruits, and large fruits. `Medina' has also an appropriate harvest calendar for the economic interest of the Huelva area.

In this study the effect of storage time on some quality parameters of two strawberry cultivars fruits storage at 4?C have been evaluated. Several quality parameters were monitored during the storage period. The samples were analyzed 1, 7, 14 and 21days during storage. Fruits were analyzed about fruit weight, sugar content, chromatic parameters L*, a*, b*, fruit firmness, total titrable acidity, pH, and sensory evaluation. The Kurdistan strawberries retained their weight throughout the experiment as opposed to the Selva strawberries which lost 0.6% of their weight per day because of dehydration. The Selva cultivar was exceptionally firmer than Kurdistan strawberries. Two cultivars were rich in vitamin C and sugar but these values were more in Kurdistan cultivar. As expected, Chroma decreased and over the storage time in two cultivars. The results of this study showed that packaged Kurdistan strawberries could prove suitable for 7 days at 4?C compare with 4 days for selva strawberries.

ABSTRACT Strawberry shows genetic variability between cultivars and, environmental elements affect the physicochemical traits of fruits when assessed under different environments. So, assessment of the stability of physicochemical traits is a tool that assists the producer in the choice of the cultivar with higher acceptance in the consumer market. This study aimed to assess the stability of strawberry cultivars based on physicochemical traits of fruits on three environments using the additive main effects with multiplicative interaction (AMMI) analysis. Thirteen strawberry cultivars were assessed in Lavras-MG, Uberlândia-MG, and Guarapuava-PR. The experimental design was in blocks with treatments at random and four replications. The stability of physicochemical traits of fruits (firmness, soluble solids, titratable acidity, soluble solids to titratable acidity ratio, vitamin C, and anthocyanins) was assessed. For the stability and performance of physicochemical traits under the three environments, the cultivars Tudla and Festival stood out for fruit firmness, Albion for soluble solids, Aromas and Tudla for titratable acidity, Sweet Charlie and Palomar for soluble solids to titratable acidity ratio, and Camarosa for vitamin C and anthocyanins.
