Stomatal characteristics during micropropagation of Wrightia tomentosa
Open accessAbstract
A deviation from usually found characteristics of stomata in Wrightia tomentosa was noted during in vitro propagation. Increase in stomatal frequency in leaves of plants grown in vitro was observed with 29.4 % malformed stomata. The stomata were spherical, wide open, did not close in detached leaves even after 3 h. The leaves exhibited 93.4 % total water loss during 3-h period. Stomatal frequency, percentage of malformed stomata and rate of water loss declined in subsequent rooting phase. Nevertheless, for high survival rate plantlets were hardened under gradually decreasing air humidity either in partially opened glass bottles containing Soilrite™ moistened with 1/4 Murashige and Skoog nutrients or in pots covered with polyethylene bags. The stomatal characteristics of hardened plants were comparable to seedlings. Survival rate was more than 95 %.

Water loss rate of tissue culture plants is significantly higher than that of adapted and greenhouse plants.
“On the other hand, their water loss rate is significantly higher than that of adapted and greenhouse plants (Joshi et al., 2006; Bertolino et al., 2019).”

Table 2 reports much greater water loss from leaves in the multiplication phase (93.44% over three hours) than from hardened plants (39.39%) or in vivo seedlings (15.23%). But rooting-phase leaves lost about as much water as hardened leaves, and the paper does not establish a statistically significant difference or identify a greenhouse-plant comparison.

Experimental — accuracy not yet measuredTissue culture plants have round and open stomata with higher stomatal density and index compared to adapted greenhouse plants.
“Tissue culture plants have round and open stomata with higher stomatal density and index compared to adapted greenhouse plants.”
From Growth, photosynthetic function, and stomatal characteristics of Persian walnut explants in vitro under different light spectra (2023) · cites this paper as Joshi et al., 2006
The paper’s results (indexed under Abstract; page unavailable) describe round, wide-open stomata in in vitro Wrightia tomentosa plants and higher stomatal frequency than in vivo plants; it also identifies greenhouse-raised seedlings among its controls. It does not report a higher stomatal index: the methods list frequency, closure, and malformation, but not index. The round shape is described specifically for multiplication-phase cultures, not all tissue-culture plants. (LLM, conf=0.88)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
