Abstract/Contents:"The plant species Leptinella maniototo (used on bowling greens in New Zealand) changes its leaf shape with different seasons, with the summer leaf form of the species being preferred from a management and playing quality perspective. Change from winter to summer leaf form is thought to be governed principally by day length. A trial was conducted to assess the potential for using conventional artificial light to manipulate the period of summer leaf formation. L. maniototo plugs were collected in early autumn 1998 whilst still in summer leaf form and placed in trays under conventional, natural light conditions. Each week over a 36-week period, selected plugs were transferred to a 24-h natural and artificial light environment where they remained for the remainder of the 36-week period. Automatic sensors were used to activate artificial light when natural daylight intensity fell below acceptable levels. Leaf form of individual plants in each group of transferred plugs (plus those remaining under conventional light conditions) was scored weekly. Results showed that under 24-hour light, plants that never experienced short day length days remained in full summer leaf form throughout the winter, but quality of foliage was poor. However, plants that had changed into full winter leaf form under natural light condions could be induced into early summer leaf form using artificial lihgt from mid-winter onwards with a reasonable quality of foliage. It was concluded that simple artificial light can be used to manipulate L. maniototo leaf form, but further field trials are required on operational bowling greens to study the effects of extended summer leaf retention on plant quality and reproductive ability of the species."
