Ascds containing Ascospoees. differences, other than shape and size, between conidia and ascospores are: (1) that ascospores, unlike conidia, are sup- posed to be the result of sexual reproduction (sexual union), and (2) that ascospores are more resistant and remain quiescent for a longer time than conidia. Chlamydospores are particularly resistant spore bodies of nonsexual origin. They are generally extremely small and covered with a thick coat. Questions for Candidates. preliminary (1) What manures are applied in practice to ratoon canes? What do they contain, and at what rate per acre are the applications made? (2) Can Bengal beans be employed as a foodstuff^ If so, why? intermediate questions. (1) Contrast the mode of living as exemplified by the Dodder {Cuscuta sp.) and Marasmius sacckari. (2) Write a short description of Zapupe fibre. FINAL QUESTIONS. (1) r4ive a short account of the recent prices of sugar and green limes. Endeavour to explain the causes of any abnormalities. (2) Mention ten useful hints in connexion with the preparation of plantation Para Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Great Britain.
