抄録 Boron (B) is an essential micro element for plants and plays important roles in the synthesis and functions of cell wall. B deficiency has been reported as one of the causes of fruit malformation in strawberries. We investigated the effect of B deficiency on flower and fruit development of forced strawberries for two cropping seasons (2015-2017). In the second season, B was resupplied for B-deficient plants and we investigated changes in fruit development. When B-free nutrient solutions were supplied, tip burn began to occur in newly emerging leaves and calyx 2 to 3 months later, and fruit malformation including seedy or only partly developed fruits with undeveloped achenes occurred frequently. However, these deficient symptoms were quickly disappeared by supplying B containing nutrient solutions. In conclusion, B nutrition is closely related to the occurrence of fruit malformation through fertility of pollen and pistils, and also development of receptacle tissue in strawberries. It should be possible to reduce fruit malformation in strawberries by proper control of B nutrition.

抄録 The objectives of this study were to (i) determine the optimum number of whole leaves to retain on a tomato plant for effective blossom-end rot (BER) management and (ii) explore the relationship between shoot calcium (Ca) and fruit Ca in non-defoliated plants in two different sized fruit cultivars, a large-fruited cultivar ‘Momotaro fight’ and a medium-fruited cultivar ‘Cindy sweet’. Treatments involved maintaining 18, 15 and 12 leaves on a plant. All lateral shoots were removed regularly throughout the growing period except the shoot closest to the flowering truss in the 18-leaf treatment. At the length of 10cm, these shoots were sampled for real time Ca determination using a hand held Ca2+ meter. In the plants defoliated to 18 leaves, BER was higher in ‘Momotaro fight’ at 10% compared to 2% in ‘Cindy sweet’. Fruit growth rate was significantly increased by defoliation in ‘Momotaro fight’, however no significant difference was observed among treatments in ‘Cindy sweet’. Defoliating to 12 leaves increased daily Ca transport rate by 59% and 37% in ‘Momotaro fight’ and ‘Cindy sweet’, respectively. Defoliating to 12 leaves increased the water-soluble Ca concentration in the distal part of fruit by 34% and 14% in ‘Momotaro fight’ and ‘Cindy sweet’, respectively. In the plants defoliated to 18 leaves where only old yellowish leaves were removed, a significant steady decrease was observed in the concentration of water soluble Ca in the distal part of fruit with increase in truss order. There was a significant linear relationship between water-soluble Ca concentration in the distal part of the fruit and Ca concentration in the lateral shoot of plants defoliated to 18 leaves. We conclude that under moderate water stress by root zone restriction and also certain other BER inductive conditions, defoliation to 12–15 leaves on a tomato plant should be a promising approach for decreasing BER incidence in susceptible large fruit cultivars.

抄録 Cold wet treatment is frequently applied to Eustoma seeds to enhance the bolting rate of plants grown under high temperatures. Our previous study indicated that cold PEG‒primed Eustoma seeds could maintain their germination rate and bolting rate even after being re‒dried for 30days and grown under high temperatures. The present study aimed to investigate whether prolonged storage after cold PEG‒priming affect the germination, growth, and flowering of Eustoma ‘Exe Lavender’ seedling. Seeds were initially cold‒primed with water or PEG‒6000 at ‒1.5 MPa for 5 weeks at 10°C in the dark and were then subjected to re‒drying and storage for 30, 60, 90 and 360days at 10°C. After 360days of storage, cold PEG‒primed seeds germinated earlier and more effectively than cold hydro‒primed seeds. Compared to the results after 30days of storage, plants grown from 360days exhibited similar bolting rate, days to bolting, bolting node and flowering rate, cut flower length and number of flower node. These results suggest that ‘Exe Lavender’ seeds can germinate and develop well even after 360days of storage and under high temperature conditions when subjected to cold PEG‒6000 treatment.
