“…Fresh weight in 'Perfecta' was highest among the three varieties. Our results confirm other studies that indicated that parameters of inflorescence architecture or fresh weight depend on environmental conditions (i.e., temperature, photosynthetic photon flux, supplemental lighting), varieties, and application of plant growth substances (Davies et al, 1996;Doi et al, 1989;Hayashi et al, 1992;Hicklenton, 1986;Hicklenton et al, 1993;Shlomo et al, 1985). Figure 3 plots parameters of architecture against fresh weight grown under four densities in 'New Face'.…”

“…One crucial determinant of filler flower quality is having clusters of multiple florets. This characteristic is decided by inflorescence architecture such as the total number of florets, number of branches, and branch length, however, understanding inflorescence architecture is difficult because the numbers of florets and branches per cut flower depend on environmental conditions and varieties (Doi et al, 1989;Hayashi et al, 1992;Hicklenton, 1986;Hicklenton et al, 1993;Shlomo et al, 1985). Moreover, particular inflorescence architectures have complex relationships with each other.…”

The effect of plant density and variety on allometry in Gypsophila paniculata L. was studied. Increasing plant density significantly reduced fresh weight, total branch length (the sum of the lengths of all primary branches), number of dichasia, number of florets per dichasium, and total number of florets in cut flowers in 'New Face'. The relationships between fresh weight and the total branch length, number of dichasia, and total number of florets were negatively allometric, isometric, and positively allometric, respectively. There were allometric relationships between fresh weight and the number of dichasia, number of florets per dichasium, and total number of florets on each branch order. The allometric exponents of regression relating the number of dichasia and the total number of florets to fresh weight increased from lower-to higher-order branches. On the other hand, the allometric exponents of regression relating the number of florets per dichasium to fresh weight were similar in almost all orders. Significant differences were found in fresh weight and parameters of inflorescence architecture among varieties grown under identical plant density. Allometric exponents relating the total branch length and number of dichasia to fresh weight, varied, and those relating the total number of florets to fresh weight were stable among varieties grown under identical plant density.

Para caracterizar o crescimento de <i>Gypsophila paniculata</i> L., efetuou-se um experimento em casa de egetação, por hidropônica, com solução nutritiva recirculante, e tendo como substrato argila expandida rígida. Os tratamentos constituíram-se de seis épocas de coleta (60, 75, 90, 105, 120 e 135 dias de idade da planta). Empregou-se o delineamento perimental inteiramente casualizado, com quatro repetições e, após a colheita, dividiram-se as plantas em folhas, caules, raízes e inflorescências, para avaliação da matéria fresca e seca em cada órgão e na planta inteira. Avaliaram-se, também, a altura da planta, o comprimento do sistema radicular e o número de folhas. Transplantaram-se as mudas com 30 dias de idade, correspondendo a última coleta, realizada 105 dias após, num total de 135 dias, ao primeiro ciclo de florescimento. A iniciação floral ocorreu em torno dos 90 dias de idade da planta. A espécie apresentou bom desenvolvimento em hidropônica, com produção média de 2,6 hastes comerciais por planta. A produção de matéria fresca e seca foi crescente durante todo o ciclo, bem como a altura da planta. A maior taxa de crescimento ocorreu em torno de 98 dias de idade.

Tomato (Lycopersicon esculentum Mill.) transplants can be affected by an intermittent physiological problem manifested by loss of apical meristem function and retarded growth rates, referred to herein as apical meristem decline (AMD). Production losses associated with this condition can be substantial. Similar abnormal and arrested development of the shoot apex has been observed in a number of other species, and referred to as blindness, budlessness, toplessness, blindwood, and bud abortion. A developmental study using scanning electron microscopy was conducted in `Agriset' tomato during an occurrence of AMD to evaluate and compare normal and afflicted plants. The AMD condition was associated with cessation of leaf primordia development and lack of flower initiation. The shoot apex of plants with AMD remained vegetative compared to normal plants which at the same age had well-differentiated flower primordia. No evidence of abortion, die back, or necrosis of the shoot apex was observed. The effects of mineral nutrient additions on symptom development varied with year. In year 1, N fertilization reduced the incidence of both AMD and retarded bud growth (i.e., the percentage of normal plants increased from 29% to 97% with N applications). Preplant applications of P, alone or in conjunction with CaCO3 and trace elements, also ameliorated AMD. In year 2, AMD was observed only at very low levels, i.e., 4% or less, and mineral nutrition had no apparent effect on AMD or normal plant number.
