Green cincau (Premna oblongifolia Merr) is a functional food plant that needs to be developed because it functions as a refreshing plant and has high chlorophyll content to increase endurance and its phytochemical content which is useful for overcoming various diseases. Green cincau (Premna oblongifolia Merr) in peat soils have not been widely cultivated due to the constraints of low soil fertility. This research is basic research aiming to determine the effect of using liquid organic fertilizers and inorganic fertilizer on the growth of green cincau in peat soil. The research was conducted in the greenhouse of the Department of Agronomy and soil analysis was carried out at the UPR Integrated Laboratory. This research used a factorial completely randomized design (CRD) consisting of 2 factors, namely factor I (Liquid Organic Fertilizer) consisting of 3 types, namely: P0 = without liquid organic fertilizer; P1 = Agrobost liquid organic fertilizer; P2 = Nasa liquid organic fertilizer; Factor II (NPK Inorganic Fertilizer) which consists of 3 levels, namely: N0 = NPK 0 g polibag-1; N1 = NPK 1 g polibag-1; N2 = NPK 2 g polibag-1. There were 9 treatment combinations, the replication was carried out 3 times so that there were 27 experimental units. Growth observation variables included a number of shoots, shoot length, number of leaves, leaf area, leaf fresh weight, number of roots, root length, and root fresh weight. Data were analyzed by analysis of variance (F test) at the 5% level, if the effect was significant, then tested it with the 5% BNJ test. The results showed that the interaction of liquid organic fertilizer and NPK inorganic fertilizer did not significantly affect all variables. The application of liquid organic fertilizer affects the number of leaves, leaf area, leaf fresh weight, number of roots and root fresh weight. Nasa organic fertilizer provides better growth than Agrobost with 13.42 leaves shoots-1, 2,623.40 cm2 leaf area polibag-1, 47.02 g polibag-1 fresh leaf weight, 12 roots number polibag-1 and 1.55 root weight g polibag-1. NPK inorganic fertilizer at a dose of 2 g polibag-1 resulted in better leaf fresh weight, namely 45.64 g polibag-1

The aim of this work was to assess growth traits during the initial developmental stages of olive seedlings, which could be correlated to time to first flowering, facilitating fast selection in olive breeding programs. The experimental material consisted of 232 olive seedlings derived from controlled crosses of 'Kalamon' with self (KA × KA), with 'Amphissis' (KA × AM), and with 'Koroneiki' (KA × KO) and from open pollination of 'Kalamon', 'Amphissis', 'Koroneiki', 'Chalkidikis', and 'Manzanillo'. Vegetative traits of the seedlings, including canopy height and diameter, length of lateral vegetation, number of leaves, mean and total leaf area per plant, leaf shape characteristics, and specific leaf area (SLA), were recorded until 15 months after sowing. The first seedlings to initiate flowers, 4 years after sowing, were also recorded. The existence of correlations between the above growth traits and time to first flowering was investigated. In single-branched seedlings 6 months after sowing, height measured at this stage was significantly correlated with the mean and total leaf area per plant, specific leaf area, and other vegetative traits measured 15 months after sowing. Seedlings with high values of these parameters were the first to initiate flowers 33 months later. Our results indicated that pre-selection of olive seedlings for earliness of first flowering is possible, based on vegetative characteristics assessed very early in their development.

Wild poinsettia (Euphorbia heterophylla L.) is a difficult-to-control weed in soybean production in Brazil that has developed resistance to herbicides, including acetolactate synthase inhibitors. We investigated the potential fitness cost associated to the Ser-653-Asn mutation that confers imazamox resistance in this weed. Plant height, leaf and stem dry weight, leaf area and seed production per plant as well as the growth indices of specific leaf area, leaf area ratio, relative growth rate and net assimilation in F2 homozygous resistant (R) and susceptible (S) wild poinsettia progenies were pairwise compared. S plants were superior in most of the traits studied. Plant heights for S and R biotypes, recorded at 95 days after planting (DAP), were 137 and 120 cm, respectively. Leaf areas were 742 and 1048 cm2 in the R and S biotypes, respectively. The dry weights of leaves and stems in the S plants were 30 and 35%, respectively, higher than in the R plants. In both biotypes, the leaves had a greater share in dry weight at early development stages, but from 50 DAP, the stem became the main contributor to the dry weight of the shoots. The R biotype produced 110 ± 4 seed plant−1, i.e., 12 ± 3% less seeds per plant than that of the S one (125 ± 7 seed plant−1). The growth indices leaf area ratio and specific leaf area were generally higher in the S biotype or similar between both biotypes; while the relative growth rate and net assimilation rate were punctually superior in the R biotype. These results demonstrate that the Ser-653-Asn mutation imposed a fitness cost in imazamox R wild poinsettia.

Leaf area per plant, total number of leaves and tillers, and total plant dry weight increased with increasing daylength over the range 8 to 24 h. The increase in the net assimilation rate and relative growth rate with increasing daily total radiation was similar to that obtained by raising the intensity of light given to plants grown under continuous illumination.During the vegetative phase of growth, the leaf area ratio decreased with increasing daylength, mostly because of an increased leaf thickness, again dependent on the level of total daily radiation. During the later stages of growth, earlier floral initiation at long daylengths caused an early decline in the leaf area ratio because of the rapid growth of the stem associated with inflorescence formation. This was a photoperiodic effect independent of the level of total daily radiation, as shown by supplementing an 8-h daylength with 8 h of low-intensity illumination.
