As a mounting medium to follow aceto-carmine the following modification of Zirkle's is suggested: Venetian turpentine, 25 ml.; phenol, 50 propionic acid, 35 acetic 10 water, 20 ml. The technic can be employed with either root-tip or pollen-mother smears, and has been used quite variety plants. It especially valuable where it desired make temporary mounts permanent. method simple, reasonable care no displacement marked cells occurs.

When root tips of Trillium erectum L. are exposed to low temperatures the chromosomes contain regions reduced diameter and staining capacity. The positions these constant within species.The number "differentiated regions" per nucleus changes with duration cold treatment, at 3 °C. reaches a maximum after 96 hr.The visible differentiation produced by disappears few hours when material is returned higher temperatures.Low cause non-differential parts be more contracted than in untreated...

By suitable treatment the somatic chromosomes of a number plants may be shown to longitudinally differentiated as size and staining capacity. Certain well defined regions appear at metaphase anaphase either understained or reduced diameter both.Exposure cold has been found produce these in two varieties rye three species Trillium.The positions differential segments have highly specific for different species.During 96-hr. period exposure affected per chromosome increases T. erectum L.After...

Studies of the major, relic, and relational coils chromosome, chromatid, chromonema length changes in meiotic, microspore, root tip chromosomes Trillium erectum L.

Contraction zygotene diakinesis, anaphase, during Chromonema elongation is associated with formation major coil its transition into relic prophase accompanied by a further elongation. The...
