摘要:

Quality and storage life of kiwifruit were investigated on fruits from shaded and exposed positions of the canopy and on fruits artificially shaded and grown in absence of light. At harvest the fruits grown in high light intensity have a high quality and can be stored for a long time; after 25 weeks of cool storage they have a soluble solids concentration > 14° Brix and a flesh firmness of c. 10 N. Fruits from shaded positions of the canopy showed significantly lower mean fresh weight and chlorophyll content (‐35%); at harvest and during storage they were slightly but consistently less firm and had lower soluble solids concentration than exposed fruits. Artificial shading of individual fruit for most of the growing season significantly reduced chlorophyll content in the mesocarp (‐77%), starch and alcohol‐soluble sugars concentration, flesh firmness, soluble content and dry matter, whereas the titratable acidity was significantly increased. The storage life of artificially shaded fruits was significantly reduced in comparison with exposed fruits, with significant increase in weight loss and fruit disease.

摘要:

The in vitro micropropagation of oca (Oxalis tuberosaMol., Oxalidaceae) on a medium with 30 g/litre versus 60 g/litre sucrose had no effect on multiplication rates and general plant phenotype. The only differences noted at the higher sucrose concentration were shortened internodes and more robust stem tissue, which provided a plant growth form more appropriate for micropropagation and transplantation out of culture. Substantially increased starch concentrations were measured in leaves, stems, and roots of the oca plants cultured on the high‐sucrose medium. Oca plants cultured in vitro on a medium with 60 g/litre sucrose showed markedly improved growth in soil following transfer out of culture. This was attributed to the in vitro plants accumulating and storing more reserves when grown on the high‐sucrose medium.

摘要:

‘Karaka’ is a new potato cultivar with high resistance to all populations of potato cyst nematode(Globodera pallidaandG. rostochiensis)that occur in New Zealand. Its main market niche is as an early to early maincrop fresh market potato, and it has some potential for french fry production.
