Spathe-Like Leaves

From: Jason Hernandez <jason.hernandez74 at yahoo.com> on 2011.03.24 at 18:47:42(21987) Lately I have been noticing something odd about the Spathiphyllum in Lowe's. The leaf nearest the inflorescence will often be partially white whilst all other leaves are the normal green. In one particularly extreme case, the plant had one completely white leaf subtended by a tiny, perfect inflorescence. Yesterday, I saw the same thing on one of those new mahogany-orange Zantedeschia cultivars: the plant had one perfect inflorescence, one inflorescence in which the spathe was open, exposing the entire spadix, and one leaf that was normal except for streaks of the spathe color. All other leaves were normal solid green. I also noticed, however, that the pink-spathed Anthuriums in the same Lowe's store do not do this; they all had normal leaves and inflorescences, with no sign of intermediates. Is this phenomenon the result of something in the commercial production techniques, that affects only certain genera?

From: "Denis" <denis at skg.com> on 2011.03.25 at 15:28:21(21990) I used to see a lot of the deformed leaves/spathes or spathes/ leaves when hormones were used to induce flowers on the spathiphyllum plants. The current hybrids are a little less seasonal in their blooming so there is less need to use hormones but the hormone are still used in springtime when there is greater need for plants in bloom. Anthurium andreanum hybrids produce flowers on each new leaf axil once the plant is mature and the growing conditions are right (light, Water, fertilizer, temperature etc.) No need to hormones induce them to flower are needed. So you should not see any funky leaves/spathes except on certain cultivars that are prone to such problems. The Anthurium Andreanum varieties will not produce pollen until the night temperatures drop consistently into the low 60’s while the flowers are in the early stages of development.

From: Susan B <honeybunny442 at yahoo.com> on 2011.03.25 at 16:45:01(21991) Dear Jason, As far as the Zantedeschia I think this is caused by the growth hormone the bulbs are dipped in. I call them "mutants" and they can be quite beautiful. They do not persist, that is, the bulb that gives the mutant leaf one year has normal growth the next. The odd inflorescence and leaves also occurs naturally, but more rarely. At least in my yard! Susan B. HTML +More East TN --0-1019547352-1301071501=:34068-- --==============`95301992477299919=
