) uprights were tagged in the field according to the corresponding bud width sizes studied: large (L; >1.0 mm); medium (M; 0.6–1.0 mm); and small (S; ≤0.5 mm). No large buds were found on fruiting uprights (FL), represented by the “X” symbol. Histological

Abstract

The standard method of preparing plant material by hand for histological study takes several days (1,2). A procedure is described herein which reduces processing time to 17 hours or less and provides tissues which are completely dehydrated and infiltrated. Up to 100 samples can be prepared within this time period. The method requires a minimum expenditure of time without sacrificing cytological detail.

Abstract

A successful host-parasite relationship was established in the stems of both resistant and susceptible snap beans (Phaseolus vulgaris L.) with the root-knot nematode Meloidogyne incognita. Thirty days after beans were planted in infested soil, all had stem galls containing egg-laying females. Histological studies showed giant cells developed from both vascular and cortical tissues.

Abstract

Avocado (Persea americana Mill., cv. Simmonds) flowers and fruitlets were histologically examined to characterize the development of disfiguring bumps and ridges, as well as to investigate possible causes of the disorder. The outer cell layers of the ovary are damaged by a small, surface-feeding insect during and soon after anthesis. Bumps and ridges form as a result of cell proliferation in the pericarp directly beneath the wounds. Circumstantial evidence suggests that two species of flower thrips (Frankliniella) are the possible causal agents.
