Testing Biodegradable Seedling Containers as an Alternative for Polythene Tubes in Tropical Small-Scale Tree Nurseries

Polythene tubes are the most commonly used seedling containers and their adoption can be attributed to high water retention that enhances seedling establishment as well as the desire for low-cost readily-available containers by nursery operators. Polythene tubes have drawbacks, however, because they adversely affect seedling root growth and are an environmental hazard. This study was conducted in Meru, Eastern Kenya, to investigate whether small-scale tree nursery operators are likely to adopt biodegradable seedling containers (cellulose papers and banana sheaths). It was hypothesised that biodegradable containers are better for seedling growth and are more environmental friendly than the widely used polythene bags. The study assessed the frequency of watering and growth (height and basal diameter) of Calliandra calothyrsus seedlings produced in various biodegradable containers under three conditions with varying watering requirements, i.e. light tree shade, shade net and polythene chambers, the first being widely used by farmers. The performance of these seedlings was later monitored in the field. Seedlings produced in biodegradable containers required more frequent watering than those in polythene bags under light tree shade and shade nets but less frequent in polythene chambers. Seedlings produced in polythene tubes had higher growth rates in the nursery, but when transplanted to the field, they were overtaken by those grown in the biodegradable containers due to transplanting shock after the polythene containers were removed. Biodegradable seedling containers can therefore be adopted in areas where water is not very limiting, and evaporation rates could be reduced and water-use efficiency improved by raising seedlings in simple polythene structures.     

Growth and Terminal Bud Formation in Picea abies Seedlings Grown with Alternating Diurnal Temperature and Different Light Qualities

The root collar diameter and the height:diameter ratio are of particular importance in container-grown seedlings where a high density in the containers may produce spindly seedlings. Temperature regimes and light quality are known to affect plant growth. The aim of this study was to identify responses in Picea abies (L.) Karst. seedlings grown with light providing different red:far-red ratios and under temperature regimes with alternating day (DT) and night temperature (NT) from negative (DT < NT) to positive (DT > NT) difference (DIF) between DT and NT. Experiments were conducted in controlled environment chambers and in a daylight phytotron. Only limited thermoperiodic responses appeared in P . abies seedlings with respect to seedling height and dry weight accumulation. The formation of terminal buds, however, was clearly delayed in seedlings grown at negative DIF. The results indicate a requirement for day extension light that is high in far-red, to prevent terminal bud formation under natural short-day conditions. An extended study should be conducted to clarify the minimum level of light intensity and the optimal light quality needed to prevent terminal bud formation under natural short-day conditions.
