Effects of cane- and spur-retained node numbers on the pre-flowering vegetative growth of cane-pruned Sauvignon blanc

In established vineyards, node number retention at winter pruning is the first step to achieving and maintaining vine balance. Balanced vines exhibit timely and quasi-uniform 100 percent budburst. To understand how vine capacity and balance are expressed before flowering, mature Sauvignon blanc vines were pruned according to a 5 [total node numbers on canes: 10, 20, 30, 40, 50] x 3 [total node numbers on spurs: 1, 2, 3] factorial design in one site, and in two other sites according to a 5 [total node numbers on canes: 10, 20, 30, 40, 50] x 2 [total node numbers on spurs: 1, 2] factorial design. Two spurs of one, two or three nodes each were retained on either side of the vine. The number of canes laid down per vine was one, two, three and four canes each of 10 nodes for the 10-, 20-, 30- and 40-node treatments, and four canes averaging 12.5 nodes for the 50-node treatment. The budburst percentage was calculated on the whole vine, canes, and spurs. Blind nodes, count shoots, non-count shoots and double shoots were counted and mapped along canes and spurs. Many non-count shoots were measured on the vine head of 10-node vines (29.5 ± 3.0 shoots, p < 0.001), compared to 50-node vines (2.8 ± 1.9 shoots, p < 0.001). 50-node vines had an overall budburst of 100 %, despite having the highest number of blind nodes (7.6 ± 0.3 nodes, p < 0.001). These were mainly located at the canes’ proximal sections relative to the vine head and were likely caused by correlative inhibition and primary bud necrosis. Cane budburst provided a more accurate assessment of the vine response to node loading than vine budburst. The number of double shoots was not associated with the vine node load, as they appeared on both low-node and high-node vines. Three-node spurs developed more blind nodes than one-node and two-node spurs (p < 0.001). Based on the findings of this research, we recommend a composite metric (cane percent budburst, cane blind node count and head shoot count) to assess vine capacity and balance between budburst and flowering, and the practice of retaining one- or two-node spurs at cane pruning is also justified.

Pengaruh Mengunyah Tebu (Saccharum Officinarum L.) dan Bengkuang (Pachyrhizus Erosus) Terhadap Perubahan Indeks Debris pada Anak Umur 8-9 Tahun di SD Adabiah Kota Padang

Debris is food residued that found on the surface of the teeth. Accumulation of debris will trigger plaque formation, causing dental caries. Debris surface area evaluated by using the debris index. One way to reduce the debris index is to eat foods that contain water and fiber such as cane and yam, because it can help the self-cleansing and stimulate salivary flow in the mastication process. The objective of the study was to find out the effect of cane and yam chewing to change the debris index in children aged 8-9 years at Adabiah Elementary School Padang. This study used a quasi experiment method with two group pretest and posttest design that used purposive sampling with a sample of 44 students and consisted of two treatment groups. Group 1 was given the instruction to chew cane in the first day and group 2 to chew yam in the second day. The results of the study is average debris index before and after chewing a cane decreased by 0,522 and chewing a yam decreased by 0,497. Paired T-Test test results showed the value of p=0.001 (p<0.05) between before and after treatment in each treatment groups. The Independent T-Test showed that the value of p=0.581 (p>0.05) between treatment groups. The Conclusion showed chewing cane and yam for children aged 8-9 years at Adabiah Elementary School Padang has an effect in decresing the debris index, but there is no significant change between both of them.

Effect of Cane on the Knee and Thorax Biomechanics in the Early Postoperative Period Following Total Knee Arthroplasty

Effect of Cane on the Knee and Thorax Biomechanics in the Early Postoperative Period Following Total Knee Arthroplasty

Which type of cane is the most efficient, based on oxygen consumption and balance capacity, in chronic stroke patients?

Canes are widely prescribed as walking aids, but little is known about the effects of canes on the physiological cost of walking. The purpose of this study was to investigate the differences in oxygen consumption associated with the gaits of hemiplegic patients in terms of balance capacity according to the type of cane used. Twenty-nine patients with chronic stroke were divided into poor-balance (n=15) and relatively-better-balance groups (n=14) based on a cutoff score of 49 on the Berg balance scale (BBS). Each patient completed three consecutive days of walking with a randomly assigned singlepoint cane, quad cane, or hemi-walker. We measured the oxygen expenditure and oxygen cost using a portable gas analyzer and heart rate during a 6-min walk test (6MWT) and a 10-m walk test (10MWT). The oxygen expenditure, gait endurance, and gait velocity were higher with the single-point cane (p<0.01) than with any of the other cane types, and the oxygen costs were lower (p<0.01) with the single-point cane among the patients with relatively better balance. The oxygen cost for the quad cane was lower (p<0.01) than that found for any the other cane types among the patients with relatively poor balance. Our study revealed that single-point canes require less oxygen use at a given speed and permits greater speed at the same oxygen consumption for hemiplegic patients with good balance. Walking aids with a greater base support may be more suitable than those with a smaller base support for patients with relatively poor balance. However, our conclusions are only preliminary because of the small sample size (KCT0001076).

Immediate Effects of Cane Use on Gait Symmetry in Individuals with Subacute Stroke

In stroke rehabilitation, there is a lack of consensus regarding the effects of cane use on gait symmetry. This study aimed to evaluate the immediate effects on gait symmetry of ambulating with a standard cane and a quad cane among individuals with subacute stroke. A within-subject experimental design was used to evaluate symmetry in in-patients with subacute stroke during ambulation on a pressure-sensitive walkway for three task conditions: with no cane, with standard single-point cane, and with quad cane. Fourteen patients were classified as symmetric (n = 5) or asymmetric (n = 9) based on their gait symmetry while walking without an aid. Overall, use of a standard cane during ambulation significantly improved symmetry in asymmetric patients (p = 0.028). In contrast, the use of a quad cane did not improve symmetry (p = 0.36). There was no effect on symmetry in symmetric patients with use of either a standard cane (p = 0.88) or a quad cane (p = 0.32). These results indicate that the immediate effect of a standard cane is to improve symmetry in patients with subacute stroke who have asymmetric gait. Future studies are required to determine the long-term effects of canes on gait symmetry in this population.

Effect of top borer(scirpophaga exerptalis wlk.) infestation on quality of jaggery

A study was undertaken to investigate the effect of cane infested with top borer (Scirpophaga exerptalis Wlk.) on gur quality during 1999 to 2001 at Sugarcane Research Institute, Shahjahanpur (U.P.). The gur samples obtained from healthy and infested canes (3rd, 4th and Sth broods) of an early maturing and high sugar variety CoS 95255 were subjected to qualitative analysis. The results revealed significant maximal losses in terms of brix pol %, purity, colour and invert sugar in the canes infested with 3rd brood followed by 4th and 5th broods of top borer in comparison to healthy canes. The minimal brix of gur (85.88) and pol % (45.56) were recorded in samples obtained from cane infested with 3rd brood as compared to those obtained from healthy canes (i.e. brix 94.18 and pol % gur 80.85). The highest invert sugar (17.10) was recorded in gur from 3rd brood infested canes as compared to those of healthy canes (6.55).

The effect of cane orientation on flower production in kiwifruit (Actinidia deliciosa)

SummaryThe effects of training replacement canes of kiwifruit either downwards (45° below horizontal) on a T-bar support, or upwards on a 60° sloping trellis were studied during one season. Training canes upwards reduced the percentage bud burst by 19% and the number of flowers per cane by 20%. There was no significant effect on the growth rate of the apical shoot, or on the number of flowers per flowering shoot. The timing of bud burst and flowering were not affected by cane orientation. The implications of these results for vine management techniques are discussed.
