Common horticultural operations, for example, preparation of potting composts, seed sowing, pricking out of seedlings, hardening off, potting up and potting on, care of glasshouse plants, digging and other forms of cultivation, lining out, planting and wrenching, preparation of seed beds, staking and tying of plants; identification of common pests and diseases, and their control; identification, origin, and proper use of commoner trees, shrubs, and herbaceous plants, including plants indigenous to New Zealand and amenable to cultivation; identification of weeds; elementary vegetable culture. (Diary to be submitted at examination time. In marginal cases the diary may determine whether or not a candidate gains a pass.)
(10) Horticultural Botany II (Classification)
Systematic botany and taxonomy, elementary knowledge of codes of nomenclature. Identification of plants, use of simple keys. Division of the plant kingdom, e.g., bacteria, algae, fungi, mosses, liverworts, ferns, gymnosperms, monocotyledons, dicotyledons. An elementary knowledge of basic plant families. (In each case the candidate will be expected to know the general characters of the family, to have studied closely 1 or 2 examples, and to be able to refer to some of the more important genera and species cultivated in gardens. Examiners will bear in mind that the same examples may not be familiar in all districts. Candidates will not be expected to know in infinite detail all of the characters of each family, but rather those which would enable them as horticulturists to recognise certain family characters.)
In addition, students will be expected to have some knowledge of the following families:
(11) Horticultural Practice II
Elementary surveying and levelling, equipment, and methods, for determining areas, levels, and grades; various types of propagation and the conditions necessary for each type; selection and use of stocks; soil mixtures for seed sowing and potting; glasshouse management; use and types of shelter and their effect on growth and yield; weed control; foremanship and the organisation of labour.
(12) Ornamental Horticulture
Practices of pruning trees and shrubs and elementary tree surgery; planting of trees and shrubs and subsequent management; a general knowledge of those commonly used for ornament, forestry, hedge, and shelter purposes; lifting and transport of trees and shrubs from one site to another; the provision of seasonal displays; the use and cultivation of annual, biennial, and perennial plants; the preparation, planting, and maintenance of lawns; the cultivation of ornamental plants under glass.
(13) Horticultural Machinery and Structures
Choice, use, and maintenance of machines and equipment; design and construction of glasshouses, shade houses, and frames; glasshouse heating and ventilation; mist propagating units, capillary and other methods of glasshouse irrigation.
(14) Oral and Practical Examination II (1 day)—A more advanced knowledge of subject 9 is assumed.
Propagation of plants by budding, grafting, inarching, aerial layering, leaf cuttings, and the more difficult types of cuttings; also different types of stocks. Pruning and planting trees and shrubs, hedges, and shelter, and times of pruning. Lawns—preparation, sowing, turfing, and maintenance. Types of glasshouse construction and heating. Types and construction of shade houses and frames. Identification of pests and diseases and their control. Identification of plants, botanical and common names, family, origin, methods of propagation and use in horticulture. The culture of fruit crops. Identification and control of common weeds. Seasonal displays both outdoors and under glass. Simple methods of determining areas, grades, and levels. (Diary to be submitted at examination time. In marginal cases the diary may determine whether or not a candidate gains a pass.)
(15) Horticultural Botany III
More advanced physiology, plant ecology, the relationship of environment to plants, including the influence of soils, water, light, temperature, wind, the chief resultant plant formations in New Zealand and their horticultural significance; the garden as a plant community; genetics and plant breeding; photoperiodism and its effect on cropping; hormonal control of plant growth, and the principles involved in the practical application of growth substances.
(16) Plant Protection III
The control of plant pests and diseases involving a knowledge of ecology, life histories, host parasite relationships. Pest and disease forecasting. Soil borne and seed borne pests and diseases and their control. Pests and diseases of glasshouse crops and their control. Spray schedules used for the main fruit and vegetable crops and in nursery and ornamental horticulture including crops under glass.
