Training trees to develop a tall spindle canopy architecture has gained popularity in high-density orchards during the past decade. However, commercially produced nursery trees often lack feathers or are unevenly branched, making initial training decisions difficult and delaying precocious fruiting. In this project, we studied the vegetative meristem activation response to partial scoring or partial girdling of the bark cambium above the bud, with and without application of 500 ppm Promalin (gibberellin4+7 + benzyladenine), tip removal of the tree leader at the silver tip stage on April 23, 2019, Promalin spray at 500 ppm at post-bloom stage on May 7, 2019, and nitrogen (N) as UAN-32 (32% N) application at five levels (60, 80, 100, 120, or 140 g actual N/tree) on June 20, 2019, in newly planted un-feathered or unevenly branched “Aztec Fuji” trees on Budagovsky 9 (Bud 9) in southwest Idaho, USA. Grower’s Short Cut trees received a heading cut to the leader at 60 cm above the ground and resulted in the emergence of 5 - 6 strong branches near the heading cut. These trees had larger trunk cross-sectional areas than scored or girdled trees. Scoring or girdling, with or without Promalin, significantly improved branching by increasing the number of branches and bourse shoots. In many cases, the effects of partial scoring, with or without Promalin, were similar to those of bark girdling which is a more risky and time-consuming process. Branches induced by scoring and girdling had sharper crotch angles relative to the vertical leader. Spraying Promalin during the post-bloom stage at 500 ppm was not as effective as scoring or girdling to initiate branches. Additional N rates or removal of the leader tip did not significantly impact branch induction.展开更多

These factors include phytosanitary problems, deficient agronomical handling, and production alternancy. Because of this, the objective of the present study was to evaluate the effect of the application of agronomical practices such as pruning, ringing, water stress, and their interaction on the rambutan alternancy. The experiment was carried out in the “La Chinita” commercial orchard located on KM. 4.5 the Huehuetan Station, municipality of Huehuetan, Chiapas, Mexico. We used 48 rambutan trees in production with an age of 14 years. Two production cycles were evaluated. The experiment was established under a divided plot experimental design in random complete blocks with a factorial arrangement and six replicates;each tree being a replicate. The study factors were: water stress, pruning, girdling, irrigation (control), and their combinations, resulting in eight treatments. The evaluation was done during flowering, fruit set, and harvest. In flowering, the treatments with permanent irrigation in both evaluated cycles (2010-2011 and 2011-2012) manifested a production alternancy behavior, with an average 36.4% flowering in the first evaluation cycle and increased to 82.1% in the second cycle. The treatments with water stress kept a proportional flowering during the first and second cycles of 97.9% and 95.3%, respectively. The water stress influenced the bunch weight (PR) variable fruit set with bigger fruits and higher bunch weight than the irrigated treatments. In production, pruning and girdling together with water deficit had no alternancy in both production cycles.展开更多

Hystricomorph rodents possess a subplacenta, swine and equines have the placental areola, equines have the chorionic girdle, and carnivores have hemophagous organs that are equivalent to the placental hematoma in ruminants. These accessory structures are specialized tissues for specific nutrient exchanges in different species, and they are adaptive modifications exhibited by domestic and wild species to remedy the nutritional deficiencies that are related to permeability of the main placenta to important nutrients for the growth and development of the fetus during the gestation.展开更多

Hence, the aims of the present study were: 1) determine prevalence of PGP and severe PGP during pregnancy and 2) compare background and lifestyle factors in addition to total physical activity level (at work, commuting, housework and recreational exercise) in those who experienced PGP and those who did not in pregnancy. Methods: Healthy pregnant women (n = 467) were allocated to the study from Oslo University Hospital, Norway. The participants filled in a validated self-administered questionnaire, Physical-Activity-Pregnancy-Questionnaire (PAPQ) in gestation-week 32 - 36. The questionnaire contained 53 questions with nine specific questions addressing PGP. The key question on PGP was asked cross-sectionally and also posed retrospectively for pre-pregnancy, 1st and 2nd trimester (During this pregnancy, did you experience any PGP?) (“Yes versus No”). Results: More than half of the women (57.5%) reported to suffer from PGP, with 18.4% reporting severe PGP. Compared the no-PGP group, women with PGP were significantly more likely to be sick-listed, multiparous, they perceived their job to be physically demanding, as well as had physically demanding household chores, including childcare. In addition, they were more prone to have experienced PGP in previous pregnancies and suffered from urinary incontinence (UI) in the current pregnancy. Most women with severe PGP reported to be sedentary in the 3rd trimester;however they performed more strengthening exercises at home than the women without PGP. Severe PGP also showed an association with standing/walking ≥50% at work. Conclusion: Women who exercised regularly in the 3rd trimester were less likely to report PGP, while job strain was associated with higher prevalence of PGP. There is a need for a prospective study with larger sample size to further evaluate if exercise has any causal association with PGP.展开更多
