“…This research revealed a medium strength (r = 0.4) correlation between fruit weight and the number of seeds per fruit. The results were consistent with those of other authors (Abbott et al, 1970;Webb, 1971Webb, , 1978 in reference to the positive correlation between fruit weight and the number of seeds. Both fruit weight and number of seeds per fruit are primarily genetically determined, cultivar specific traits and are influenced by the whole complex of various factors, including the success rate of fertilization.…”

Fruit set of blackcurrant (Ribes nigrum L.) cultivars 'Almo', ' Ats', ' Elo', and ' Karri' and four breeder's selections was investigated under open pollination, artificial, and natural self-pollination conditions in 2006-2007. The percentage of fertilized flowers, number of seeds per fruit, and fruit weight was largely genotype dependant, but it was also affected by the pollination conditions. All genotypes proved to be self-fertile, but the best fruit set occurred under open pollination conditions. There was a medium strength positive correlation between fertilization rate and fruit weight, and a below average positive correlation between the number of seeds and fruit weight.

“…This is supported by the early ripening observed in MF of 'Camarosa' which has been shown to be closely related to an increase in anthocyanin (responsible for the red colour of the fruit) linked to a decrease in auxins levels (Given et al, 1988). However, it is striking that MF of 'Medina' did not display a marked loss in size in spite of the pronounced decrease of the total number of achenes per fruit (Abbott et al, 1970;Strik & Proctor, 1988), and of the higher proportion of 'small' achenes observed in MF compared to WF. This result might be pointing out differences among cultivars in the ability of 'big' achenes to secrete auxins (Dreher & Poovaiah, 1982) and/or a stronger regulation of achenes metabolism in 'Medina' strawberry.…”

“…Genetics contribution is illustrated by the marked differences among cultivars in the percentage of MF naturally occurring under field conditions, which is consistent with previous reports (Carew et al, 2003), and by the cultivar-dependent differences among MF. However, it is striking that MF of 'Medina' did not display a marked loss in size in spite of the pronounced decrease of the total number of achenes per fruit (Abbott et al, 1970;Strik & Proctor, 1988), and of the higher proportion of 'small' achenes observed in MF compared to WF. In these cultivars, the smaller fruit size of MF is consistent with the larger amount (>41%) of 'small' achenes (<0.4 mm) in the distorted region of the fruit, which have presumably lost completely their viability (i.e.…”

Fruit misshapen in strawberry cultivars (Fragaria×ananassa) is related to achenes functionality

Fruit deformation is a phenomenon commonly observed in commercial strawberry cultivars (Fragaria × ananassa) with a negative impact on the economic benefit of crop production. To better understand this physiopathy, we evaluated fruit size and the relative amount of 'small' (<0.4 mm) and 'big' achenes (>0.6 mm) in misshapen (MF) and well-formed (WF) fruits from 'Camarosa', 'Ventana' and 'Medina' strawberry cultivars growing in the field. In 'Camarosa', size-dependent achenes functionality was assessed by analysing achenes germinability and differences in time to ripening between MF and WF. We found that the occurrence of fruit deformation was not only strongly dependent on the cultivar (i.e. genetic factor) but also was promoted by low temperatures (i.e. environmental factor). Regardless of the cultivar, MF showed higher percentage of 'small' non-functional achenes than WF, indicating a failure in achene development, which could be related to the functional integrity of reproductive structures. To test this hypothesis, we performed an experiment by pollinating strawberry flowers with pollen developed under low and mild temperatures. Low temperatures reduced pollen viability, and flowers pollinated with low quality pollen led to a higher amount of MF. However, fruit deformation was not completely explained by differences in pollen quality, neither by differences in pistil maturity and receptivity nor ovule viability, suggesting that non-functional achenes might result from a disruption in postfertilisation processes such as embryo abortion as a consequence of low temperatures.

“…Boundary line analysis has been proposed as an alternative to procedures such as linear regression for modelling biological responses. Abbot, Best & Webb ( 1970) plotted strawberry weights against achene numbers, and showed that points fell on or below a distinct upper boundary line. They proposed that this boundary line represented the maximum response of berry weight to a potentially limiting factor (the number of fertilised carpels).…”

An empirical method for describing the joint effects of environmental and other variables on crop yield

There is considerable interest in developing understanding of the spatial variation of crop yield within fields in relation to the spatial variation of environmental factors. Such understanding might allow inputs to crops to be used more efficiently by spatially variable application. The joint action of factors on crop yield (whether controlled treatments or environmental variables) may be additive, interactive or potentially limiting in the sense of von Liebig's "Law of the Minimum". The nature of the joint action of an input and environmental factors has profound implications for the possibility of improving the efficiency of use of the input by spatially variable application. Conventional methods for analysing data on such factors and yield (e.g. multiple regression) make specific assumptions compatible only with a narrow range of permissible models. A procedure is proposed and demonstrated in this paper for the exploratory analysis of data from experiments and/or crop surveys in order to describe the joint action of important factors on crop yield. The procedure could be applied to specific experiments in order to indicate whether there is any scope for optimising rates of an input with respect to one or more spatially variable factors, and for indicating whether the relationship between the local optimum rate of the input and values of these factors is simple (factors act additively or in accordance with the Law of the Minimum) or complex (factors interact).
