Intensity Of Response

The role of different temperature regimes (low, 18 °C day: 15 °C night (LTR); intermediate, 23 °C day: 18 °C night (ITR); and high, 28 °C day: 23 °C night (HTR)) in the development of tomato (Lycopersicon esculentum Mill.) flowers was studied. In general, flowers produced in LTR contained significantly greater numbers of petals, stamens, carpels, and locules than did plants grown in HTR. In ITR, the number of these organs was intermediate to plants grown in LTR and HTR, but was not significantly different from them in all cases. Gibberellic acid (GA3) also induced an increase in the number of petals, stamens, carpels, and locules; however, its effect was much greater on plants grown in ITR and HTR than on LTR, implying that LTR may produce at least part of its effect through increased levels of endogenous gibberellins. The intensity of response to different temperature regimes was variable for each of the three cultivars studied.

Number Of Seeds

Four sweet potato [Ipomoea batatas (L.) Lam.] cultivars responded differently to growth regulator application for number of flowers produced, percentage capsule set, and number of seeds produced. Gibberellic acid, 2,4-D, and BA application resulted in the highest number of flowers by `Jewel', `Shore Gold', and `Vardaman) plants, respectively. Application of GA3 to `Jewel', 2,4-D or ethephon to `Shore Gold', and BA to `Vardaman' produced the highest number of seeds. Grafting to rootstock of Z. carnea Jacq. spp. fistulosa (Mart. ex Choisy) D. Austin increased flower numbers, percentage capsule set, and number of seeds in all cultivars. The effects of growth regulators and grafting were additive for flower numbers, percentage capsule set, and number of seeds. Chemical names used: N-(phenylmethyl)-1H-purin-6-amine (BA), (2,4-dichlorophenoxy) acetic acid (2,4-D), (2-chloroethyl) phosphoric acid (ethephon), and (1α, 2β, 4a α, 4b β, 10)-2,4a,7-trihydroxy-1-methy1-8-methylenegibb-3-ene-1,10-dicarboxylic acid 1,4a-Iactone (gibberellic acid; GA3).
