Morpho-phenological and agronomic performance of strawberry cultivars with different photoperiodic flowering responses

Abstract

The adaptability of the strawberry is known; however, little is known about the morphological and agronomic performance of these runner plants when transplanted in the Southern Hemisphere. The objective of this study was to evaluate whether strawberry cultivars classified according to their flowering differ in morpho-phenology and agronomic performance. Six cultivars of strawberry were used, two of which were Short Day (SD), Camarosa and Camino Real, and four of which were Neutral Day (ND), Aromas, Albion, Monterey, and San Andreas. The cultivars were arranged in a randomized complete block design with four blocks. The research developed in two parts: one part as descriptive research (morphological performance and phenology) and the other part as explanatory research (morphology of the root system and the agronomic performance). In the descriptive research, the data about the strawberry cultivars were presented in a descriptive way. The data on morpho-agronomic performance (explanatory research) were submitted to analysis of variance and Tukey’s test at a 5% probability of error. It is inferred that there is variability among cultivars regardless of their classification in terms of flowering. In all cultivars, we observed a botanical structure called a hypsophyll that is not included in the morphological descriptors of the species.

Multivariate analysis of strawberry experiments: where are we now and where can we go?

“…The recommendation of Camarosa instead of Albion would provide undesired values for productive traits such as higher number and weight of non-commercial fruits, phenological traits such as higher period to the beginning of the harvest, and qualitative traits such as lower values of total soluble solids and esh rmness. Previous studies have also shown that the beginning of owering is similar for Camarosa and Albion, but full owering is achieved early in Albion (Castoldi da Costa et al, 2020). This results in the late beginning of harvest for Camarosa compared to Albion ( Supplementary Fig.…”

“…Considering a univariate recommendation based on fruit yield solely, Camarosa cultivar would be recommended instead Albion since, on average, it is more productive ( Supplementary Fig S16A). Previous studies also reported the high total fresh fruit mass of Camarosa compared to Albion (Castoldi da Costa et al, 2020). This is explained mainly because Camarosa can increase the emission of crowns compared to Albion, resulting in a higher number of leaves.…”

MGIDI: a powerful tool to analyze plant multivariate data

“…The recommendation of Camarosa with transplants of National origin based on FY would result in higher fruit production. Previous studies also reported a greater total fresh fruit mass of Camarosa compared to Albion [ 49 ]. This is explained mainly because Camarosa can increase the emission of crowns compared to Albion, resulting in a higher number of leaves.…”

“…1.4). Previous studies have also shown that the beginning of flowering is similar for Camarosa and Albion, but full flowering is achieved later in the Albion cultivar [ 49 ]; this characteristic may be undesired by growers.…”

Exploring genetic variability under extended photoperiod in lentil (Lens Culinaris Medik): vegetative and phenological differentiation according to genetic material’s origins

“…The extended photoperiod is one of the methods that reduce the duration of the plant cycles [ 23 , 24 ]. In many studies, it has been demonstrated that extended photoperiod have a positive benefit effect for breeding, by accelerating flowering and reducing plant life cycle in Safflower [ 25 ], Strawberry [ 26 ], Soybean [ 27 ], Barley [ 28 ], Wheat [ 29 ], Chickpea [ 30 ], Faba-Bean [ 31 ] and Lentil [ 23 , 32 , 33 ]. The extended photoperiod can be achieved with artificial light [ 34 ].…”
