The purpose of this study was to investigate differences in stomatal index among backcross progeny ofSolanum commersonii (freezing tolerant) andSolanum cardiophyllum (freezing sensitive) to assess the feasibility of using this trait as a marker for screeningSolanum populations for freezing tolerance. Measurements were taken on three terminal fully-expanded leaflets per genotype by completing microscopic examination of epidermal impressions made in partially dissolved cellophane tape.

Variation in Leaf Anatomy of Pecan Cultivars from Three Ecogeographic Locations
The study suggests that differences in stomatal density and epidermal cell density in pecans are cultivar specific rather than being determined by environmental factors. Expand
Variation in Anatomical Characteristics in Leaves of Pecan Seedstocks from Mexico and the United States
Although isotopic carbon discrimination did not vary greatly in Mexican seedstocks, the reduction in stomatal density in pecan trees from areas with reduced annual precipitation suggest the presence of an anatomical feature to reduce water losses. Expand
Comparing Methods of Ploidy Estimation in Potato (Solanum) Species
Three predictors of ploidy were tested, particularly seeking the quickest, simplest, and most reliable: Chloroplast number per guard cell (C#), guard cell length (GC), and pollen diameter (P), with a total of seven variations in methods of preparation. Expand
Ectopic AtCBF1 over-expression enhances freezing tolerance and induces cold acclimation-associated physiological modifications in potato.
The results suggest an endogenous CBFpathway is involved in many of the structural, biochemical and physiological alterations associated with cold acclimation in these Solanum species. Expand
Variation in ecogeographical traits of pecan cultivars and provenances
The stability of certain leaf anatomical characteristics, such as stomatal density, for pecan cultivars grown at different locations confirms that these traits can be used for screening provenances with desirable Leaf anatomical characteristics for breeding and cultivar development. Expand
Assessment of the Diversity of Leaf Epidermal Traits of Dipcadi Filamentosum Medik Among Different Co-Geographical Regions in Nigeria
The variables observed among the 4 eco-geographical populations of D. filamentosum showed that effects of environmental factors are partial on the leaf epidermal traits of the plant. Expand


Inheritance of freezing resistance in tuber-bearing Solanum species: evidence for independent genetic control of nonacclimated freezing tolerance and cold acclimation capacity.
The results show that it should be possible to incorporate the two main traits associated with frost or winter survival from wild germ plasm into cultivated crop plants by independent selection, and demonstrates relative simplicity of the inheritance of cold acclimation. Expand
Growth and development temperature influences level of tolerance to high light stress.
Acclimation of S. tuberosum to lower temperature growth conditions with a constant light environment results in the increased capacity of photosynthetic tissue to tolerate high light stress at chilling temperature and following growth and development at relatively high temperatures S. commersonii, a frost- and heat-tolerant wild species, has a much greater tolerance to the high light Stress at chilling temperatures.

The Anatomy of the Leaf of Potato, Solanum tuberosum L. 'Russet Burbank'
In the compound leaf of potato, Solanum tuberosum `Russet Burbank,' phloem anastomoses occur throughout the petiole-rachis-midrib axis and are common in both the adaxial and abaxial phloem. XylemExpand

A comparison study of photosynthetic activity in Lemna-GIBBA and its relation to light and temperature shows clear patterns of alternation between the former and the latter. Expand
