Description

MULTI-STEM SEED POTATO TUBERS
The present invention relates to a method of increasing the number of stems on a seed potato tuber.
seed potato tubers are stored in commercial potato stores at 3.0-3.5 C in the absence of any chemical sprout suppressant. At this temperature range, the tubers break dormancy after a few months but the sprouts are unable to grow further.
Proposed Regulatory Decision Document PRDD 2001-04 relating to ethylene Eco Sprout Guard prepared by Health Canada discloses the use of ethylene for suppressing growth of potato tuber stems during storage.
In commercial scale trials conducted on Solanum tuberosum Russet Burbank cultivar over the period 1992-1995, tubers were stored in a storage building and the concentration of ethylene in the building was raised to 4 ppm once the tubers had been permitted to suberize and cool to SAC. Ethylene was observed to reduce the sprout number as well as the sprout weight and length.
Surprisingly, the inventors have found that storage of seed potato tubers at elevated ethylene concentrations (10-50 ppm) prior to planting results in an increased number of healthy stems on each tuber on planting and hence an increased number of smaller tuber-e per plant.
Summary of Invention
In a first aspect of the invention, a method for increasing the number of stems on a seed potato tuber is provided comprising the steps of: a) storing a seed potato tuber at a temperature in the range of 3-15 C under an atmosphere comprising at least 8 ppm ethylene for at least 8 weeks; and then b) removing the seed potato tuber from storage under the said ethylene atmosphere for subsequent planting. l
The storage temperature can be in the range of 5-13 C, and is ideally 10 C. The ethylene concentration can be in the range of 8-100 ppm, more preferably 8-75 ppm, more particularly in the range of 8-13 ppm and ideally 10 ppm. The seed potato tuber can be stored for at least 12 weeks.
The seed potato tuber can, optionally, be selected from one of cultivar Maris Peer or Charlotte.
In another aspect of the invention, a seed potato tuber is provided treated by the foregoing method.
Brief Description of the Figures
The invention will now be exemplified with reference to Figure which shows a planting regime for Solanum tuberosum Maris Peer and Charlotte cu ltiva rs.
Detailed Description of Invention
Maris Peer and Charlotte cultivar seed potato tubers were lifted in September/October 2001 and stored in an commercial potato store at 9 C for about 10 days in order for any wounds on the tubers to heal. This process is known as suberization and involves the impregnation of cell walls with suberin, a fatty or waxy substance present in the walls of cork cells, rendering them impermeable to water and resistant to decay. The storage temperature was then reduced to 4 C. On i4th January 2002, when the tubers first started to sprout, the storage temperature was raised to about 10 C and ethylene introduced at an atmospheric concentration range of 10-50 ppm. The tubers were then removed from the enhanced ethylene atmosphere on i7th April 2002. Before planting, the tubers were able to degas over a period of 3-4 days.
The ethylene treated seed potato tubers were then planted on 25th April 2002 in accordance with the planting regime illustrated in Figure:1.
So Figure 1 shoves 32 plots half of which are planted with the Maris Peer cultivar and half of which are planted with the Charlotte cultivar. Each plot is planted with three rows of ten tubers at 8 inch intervals. Each group of 16 plots includes four plots of untreated seed tubers (UNT), four plots of ethylene treated seed tubers (TY), four plots of seed tubers treated with 2-aminoethoxyvinyl glycine (EB) and four plots of ethylene treated seed tubers subsequently treated with 2-aminoethoxyvinyl glycine (TY + EB). The 2-aminoethoxyvinyl glycine was applied to the tubers by spray the day before planting at a concentration of 43g/hectare. 2aminoethoxyvinyl glycine is thought to inhibit endogenous ethylene production.
The soil type used in the plots was sandy loam from Nacton farm. No nematicide was applied. Fertiliser was applied at an equivalent nitrogen concentration of 140kg/hectare.
The burn off date was 12th July 2002 and the potato tubers were harvested on 5th August 2002. The process of burn off involves chopping down of the plant and treatment of the remaining stem with a gas burner or sulphuric acid. The process prevents further growth of the tuber.
The results are summarised in tables 1-3 hereinbelow. !
