The Relationship

Successive batches of tomato plants were raised throughout two years under ideal conditions in a glasshouse, and the intervals between sowing and the attainment of different stages in vegetative and reproductive growth were determined. The relationship between the season and the growing period was a simple one. There was a linear increase in the duration of the growing period between 21 September and 21 December, and a linear decrease between 21 December and 21 March. In the third season, from 21 March to 21 September, the growing period remained practically constant. The pattern of the relationship between the season and the growing period was maintained over a range of temperatures and light levels. Growth data from the literature for carnations, roses, radishes and lettuces under glass could be described in the same way. (Abstract retrieved from CAB Abstracts by CABI’s permission)

The effect of application methods with different boron levels on the growth, fruit quality and flavor of tomato (Solanum lycopersicum L., cv. ‘Jinpeng No.1’) were investigated under greenhouse conditions. Seven treatments used included two application methods (leaf and root application) with four boron levels (0, 1.9, 3.8 and 5.7 mg∙L−1 H3BO3). Experimental outcomes revealed that both application methods significantly increased net photosynthetic rate and chlorophyll content, and stabilized leaf structure of tomato. Leaf spray of 1.9 mg∙L−1 H3BO3 was more effective at improving plant growth and photosynthetic indices in tomato compared to other treatments. Additionally, root application of 3.8 mg∙L−1 H3BO3 resulted in better comprehensive attributes of fruit quality and flavor than other treatments in terms of amounts of lycopene, β-carotene, soluble protein, the sugar/acid ratio and characteristic aromatic compounds in fruit. The appropriate application of boron can effectively improve the growth and development of tomato, and change the quality and flavor of fruit, two application methods with four boron levels had different effects on tomato.

Cell and tissue interactions are a basic aspect of eukaryotic growth and development. While cell-to-cell interactions involving recognition and incompatibility have been studied extensively in animals, there is no known antigen-antibody reaction in plants and the recognition mechanisms operating in plant grafts have been virtually neglected.An ultrastructural study of the Sedum telephoides/Solanum pennellii graft was undertaken to define possible mechanisms of plant graft incompatibility. Grafts were surgically dissected from greenhouse grown plants at various times over 1-4 weeks and prepared for EM employing variations in the standard fixation and embedding procedure. Stock and scion adhere within 6 days after grafting. Following progressive cell senescence in both Sedum and Solanum, the graft interface appears as a band of 8-11 crushed cells after 2 weeks (Fig. 1, I). Trapped between the buckled cell walls are densely staining cytoplasmic remnants and residual starch grains, an initial product of wound reactions in plants.

Calcium is an important element in the growth and development of plants and one form of calcium is calcium oxalate. Calcium oxalate has been found in leaf seed, stem material plant tissue culture, fungi and lichen using one or more of the following methods—polarized light microscopy (PLM), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and x-ray diffraction.Two methods are presented here for qualitatively estimating calcium oxalate in dried or fixed tobacco (Nicotiana) leaf from different stalk positions using PLM. SEM, coupled with energy dispersive x-ray spectrometry (EDS), and powder x-ray diffraction were used to verify that the crystals observed in the dried leaf with PLM were calcium oxalate.
